The United States decided to create a rocket on low enriched uranium as part of the lunar program

US Defense Research Agency DARPA Reveals Funding for a Space Program. This is primarily a program that is associated with the creation of a rocket capable of delivering cargo to the lunar orbit.

So, in the budget for 2021, $158 million is allocated to the DARPA program. Part of these funds should go to the creation of a rocket with a nuclear power plant. In addition, the funds will be spent on the creation of new space robots, which will serve objects in outer space.

The United States notes that it is necessary to hurry with a nuclear fuel rocket, as “US competitors may be the first to create a rocket that can be used to fly to the Moon and its orbit.

The project is currently designated as DRACO-21 (Demonstrator of a rocket for near-moon operations). The basis for the operation of its engine should be low-enriched uranium (from 5 to 20 percent). It's about uranium U-235.

It is noteworthy that the customer for the creation of the spacecraft are the US Air Force. This automatically means that the United States is about to turn the lunar orbit into a sphere of its military interests.

Even the American portal Breaking Defense writes that this program is actually a cover for the Pentagon’s military ambitions.

Well, HOW did they fly to the moon once right now they can’t ??

This is our USSR lunar tractor!

[hydrox]

It’s ours, it’s ours, and it’s clear that they’re not going to make its replica, but here’s where they are going to take the low-enriched U-235, if they themselves can’t produce it, they bought it from us earlier (for space power supplies of high-current equipment (according to mine for this, and the bill went to kilograms)).
So for the engine you need a lot more - where will they get ???

[asv363]

Uranium-235 in the United States is supplied by many countries. The leader in deliveries to the world market over the past 5 years has been Kazakhstan.

[Chigi]

Kazakhstan is a leader in the supply of uranium ore, the enrichment process in Kazakhstan is not carried out.

There was not uranium, but plutonium. Some were produced by ourselves, some were bought in the Russian Federation, now they are produced

It was only mined there in Soviet times, in the Dzhezkazgan region, but it wasn’t enriched, now I don’t know.

[asv363]

Natural uranium is mined in Kazakhstan, it is cheapest to enrich it here in Russia, for example, at UEKhK. For a long time Kazakhstan, represented by NAC Kazatomprom, owned 25% of UEHK shares, but recently sold them back to TVEL JSC, keeping one "golden" share.

In addition, uranium enrichment plants in the United States were built by Europeans, in particular the URENCO company (Great Britain, the Netherlands and the Federal Republic of Germany in equal shares). Here is a link to their "candle factory" in New Mexico:

[maratkoRuEkb]

it is impossible to restore such an industry in a short time, which means that when the moment of that "vital" comes, they will have nothing. If they have not financed their production and R&D since the 90s, then the gap is 20-30 years. They can't catch up.

First of all, you do not know that with production, it is most likely frozen, the machines are in stock. If part of the machines is lost - hello cnc machines, you just create the lost in a short time, they, unlike us, do not need Simenovsky turbines, they produce almost everything themselves, and what they do not produce, because the allies are clearly bigger than Belarus with Syria and Serbia. The technology is lost when the atomic bomb fell on you, all the plants with the blueprints burned down, the employees died, and only you had the same technology, or when your country fell apart and the critical production went not to you, but to the countries that were in your composition, but now they are your enemies. And when you just turned production it is not lost. When you take the pump out of the barrel and put it in the shed, this does not mean that you have lost the watering technology for cucumbers, it means that winter has come and you do not need it, when it comes to the news, you put it back in the barrel, read the instructions for mb. And you don’t have to catch up with anyone, plutonium will not become better with the new technology, if you learned how to mine it, then it will not be difficult to repeat, and they are not so dumb to deprive yourself of nuclear weapons

[maratkoRuEkb]

you just don’t know what happened to them, many years have passed and that equipment is already scrap. Hi, CNC machines ... and what will they produce on them? Centrifuges 20 years ago? Do you think it's so easy to find components 20 years ago? all supply chains of suppliers have already been lost, who will supply them with what they need? yes no one. Replace part of the components with a modern element base? this is a lot of time, consider it a full-fledged R&D.
And you are mistaken in saying that they produce almost everything themselves, you wanted to say they transferred almost all production to China! And as for the employees, do you apparently think that they have a bunch of engineers in their free time sitting and studying books on nuclear equipment? They do not have competent people for such work, it’s not for you to look at the YouTube video and voila you are an engineer.
Your words "And you don't need to catch up with anyone" say everything about you - I see here, I don't see here because I don't hachu, bububu. And your unwillingness to see the obvious will not change reality ... they lagged behind us and their whole branch of production was destroyed, because it is uncompetitive, the market has decided, capitalism is so ...

They developed an atomic bomb in 3 years from 0. They spent all research on the design of the uranium enrichment bomb and on the construction of reactors to produce plutonium and on the construction of plants for the separation of this plutonium from irradiated uranium blocks in 3 years. And now, when everything is ready, they will do it instantly. That you in a fit of patriotism cheers do not notice the obvious things. They lagged behind in the production of fuel moxs, in the processing of spent assemblies and nuclear weapons, in the construction of reactors, but not in the production and enrichment of uranium and plutonium

So I’m trying to find out what kind of miracle technology the Miricans are going to hang on our ears !?

[astepanov]

... What kind of rocket? How does it compare with the megawatt class nuclear electric propulsion system we are developing? Our development is designed to work in space and cannot independently take off from the ground - but it has a specific impulse many times greater than that of a nuclear rocket engine. Tests of the mock-up of the engine in space are scheduled but this year, and full-scale tests, as always, are impossible due to the lack of infrastructure on Vostochny and, probably, the lack of a suitable launch vehicle. Are the Americans really going to build a rocket in the manner of those tested in the seventies, or do they want to follow the same path as us? I think it's more likely the second: the launch of a reactor-powered rocket is too dangerous, and does not give noticeable advantages.

Today's blog guest: Sergei Kud-Sverchkov (che3000), a test cosmonaut-test cosmonaut of the Roscosmos. He maintains his blog, in which he talks about the daily life of Russian cosmonauts, and how he is preparing for his first flight. Among other things, he told how he visited the Lunar Samples Laboratory, the place where the lunar soil mined during the Apollo program, is stored on a business trip to the USA. The topic of lunar soil often pops up in discussions of the lunar program. Some have a misconceptionthat all the soil has disappeared or that all samples are classified and are not shown to anyone. Sergey’s photo report demonstrates that this is precisely a fallacy.

Lunar Samples Laboratory

Today we, Oleg Skrypochka and me, had an amazing opportunity to get into the lunar soil storage, located on the territory of the Space Center named after Johnson.

MOSCOW, December 11 - RIA Novosti. Samples of lunar soil, which the Americans delivered to Earth during the Apollo manned space flight program in 1961-1972, cannot be faked, director of the Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences Yuri Kostitsyn told RIA Novosti.
The USA in 1961 adopted the Apollo manned space flight program for the first manned landing on the Moon. As part of the program, seven missions were sent to the moon from 1961 to 1972, one of which was unsuccessful. The program ended in 1975, the Americans delivered 300 kilograms of lunar soil to Earth.

The RAS talked about the unique features of the lunar soil
"It is impossible to fake the lunar soil. The Americans brought about 300 kilograms of soil to the Earth during seven lunar missions, mainly basalt. It was studied in laboratories by scientists from different countries - Germany, France, the USSR. There are also basalts on Earth, but in terms of chemical composition, properties, structure, they differ significantly from the lunar. There are no rocks older than 3,7 billion years on Earth, and the Americans brought a substance that is more than four billion years old, which is very close to the age of the solar system, "said Kostitsyn.
He noted that the Americans brought to Earth including regolith, which is not on our planet.

A radioisotope Ru-106 (half-life of 368,2 days) was detected in samples of radioactive aerosols from observation points Argayash and Novogorny. The concentration of Ru-106 on these aerosol samples was - n * 10-2 Bq / m3

On September 26-27, the decay products of Ru-106 were recorded in the Republic of Tatarstan.

On September 27-28, high pollution of aerosol samples and precipitation was recorded in Volgograd and Rostov-on-Don.

This is a lie, low enriched uranium, one that is prone to a nuclear reaction, it is uranium 235 that assimilates delayed neutrons for fission, in order to slow down these neutrons it is necessary to add a moderator, on satellites there will be plutonium 239, working from what is, without a moderator. So that the moderator does not interfere with the cooling of the reactor, you need a large radiator, this is not for space. Although I repent, they can use another reactor, very heavy. This is a subjective opinion.

There are different ways. There, objects either receive radiation and heat up, or radiate themselves and cool.
In order to cool properly, you need to interact with something that will take heat - the vacuum is not suitable for this because there is no horseradish in it.
Therefore, objects in a vacuum heat up well and cool poorly.

[Errr]

... objects in a vacuum heat up well and cool poorly.

Even in near-earth orbit (not in deep space), objects are much more likely to cool off than to heat up. If this topic is really interesting to you, you can familiarize yourself with it in more detail using the example of the thermal control system of the Soviet orbital station "Salyut-6" at https://engineering-ru.livejournal.com/310096.html.

Depending on which objects, the working fuel assembly of the FIGS cools down because it generates more heat than it emits, one has to be smart with cooling.
Brick, on the contrary, does not produce any heat, and it has no choice but to cool down. (unless of course the sun warms up to plus one hundred and sixty).

[Errr]

Salute-6 really had to be heated, it did not have enough heat from the sun.
And about the fact that the stove is hot so far in the firebox and the stove, all rural schoolchildren in the course have not burned out.

that the stove is hot while all the rural schoolchildren in the course burned out in the firebox and the stove did not burn out.

If the stove is in vacuum, then it will cool longer than if it were immersed in a substance with a temperature of -270 ° C, although it seems that the temperature is close to absolute zero both, but there are no molecules in the vacuum with which the stove will interact transferring them its thermal energy.

In the article that you cited, we are talking about temperature-sensitive devices located on the shadow side, their sun did not warm.

... however, in a vacuum there are no molecules with which the stove will interact transferring its thermal energy to them.

You are trying to consider convection, which in the absence of gravity simply does not exist. If you carefully read the article we are considering about the Salyut-6 temperature control system, it is easy to notice that:

Excess heat is transferred in the liquid-liquid heat exchanger to the external circuit and is "dumped" into space from the radiation surface.

Those. in the absence of convection, even almost in a vacuum, it is possible to discharge excess heat using elementary radiation from a radiator in the infrared range.
Next you write:

I don’t know where in this article you found this, but I didn’t mean this at all, but that:

When there is no crew at the station and its equipment produces little heat, the air temperature in the pressurized compartment decreases. In order for it not to fall below the permissible limit, an electric heater is provided as part of the thermal control system

Do you think this electric heater would be needed if there was enough external heating from the Sun? Personally, I think that it would be possible to dispense with the elementary transfer of heat from the overheated side to the supercooled elementary circulation of the coolant in the temperature control system. This is just mentioned in the text of the article:

The heat carrier of the heating circuit also circulates along the walls of the station (9), heating the cooled and cooled parts of them, or, in other words, equalizing their temperatures.

Well, since the station is not always on the sunny side, there is no external heating in the shadow.

[Errr]

That's right. I'm exactly the same. With a period of his (Salute-6) circulation of less than 90 minutes in the shade, he periodically was no more than 45 minutes. The case of the working (main) compartment of this station (as well as its entire transition compartment, together with the equipment installed on its surface) was closed by screen-vacuum thermal insulation, and the zone of its larger diameter was also covered with a fiberglass casing. Therefore, to maintain the normal operating temperature of the station, a high-power heater was not required.

So that the moderator does not interfere with the cooling of the reactor, you need a large radiator, this is not for space.

If the reactor heats the liquefied gas, then this gas cools it.

... US competitors may be the first to create a rocket that can be used to fly to the moon and its orbit.

Woblin! "Who's first" is that important? As for me, it is really important to create and use it seamlessly for the benefit of your country. Some kind of childishness: "I am the first, no, I am the first!"

[Proton]

A vigorous engine, it’s good of course, and it will start from the Earth as it will on a trampoline or again on our RD-180

[Blackmokona]

On Falcons for example

or again on our rd-180

Ah, in another Atlas-5 verticalize with the engine number 102T

[Dargavs]

Quote: Gray Brother

The rocket does not heat the incoming air, but the working fluid.

That is why this statement is "blizzard".

[fk7777777]

Yes, I also don’t understand where the air comes from in a complete vacuum? ...

[Prjanik]

And anything heard about the cooling system for our nuclear power plants?

[Russian_man]

Conventional engines they have are bad - they do not pull, break, burn - they fly on our RD-180, but the American space program, according to the version of the world's shit media, is much cooler than the Russian one. Now they suddenly started to make nuclear engines, and everything was so cool there that they were already going to Mars) ...
... One thing is clear for sure - either again they will crap too soon from the strain or .... our "patriotic" Putinists finally decided to resell advanced research and test results in the field of ... flights to Mars at a higher price) ...

[ultra]

there is no Russian yet, it’s Soviet.

[Lord of the Sith]

Apart from the appearance, there is almost nothing Soviet there.
Although, on the other hand, what's wrong with the Soviet backlog? For ten years the Yankees themselves have not flown, but this does not prevent them from pompously believing that they have the best space program in the world.

[Lekz]

It seems that the Yankees poured out another bullet for us. Or twist with the appointment. The design of the carrier with nuclear power plants was carried out in our country back in the 60s. So far, prospects for the use of nuclear power plants are not visible.

[iouris]

Trump: "This is a sooooo fast and sooooo environmentally friendly rocket: five, seven times and even faster and more environmentally friendly. The Russians were the first to create such missiles because they learned about Obama's plans. Obama told them himself."

[Chigi]

Guys, I can’t read most of the posts without laughing.
Today is not Friday, why so much misinformation?
Nuclear power plants are my specialty. And I know what I'm talking about

ours has everything except money

money by the way, Ros (Gozin) has space. so it’s not in them but in those who saw them

[Klingon]

hey minusers, you want to say that there is no monstrous dough cut in Roscosmosp? you at least do not lie to yourself how much what Roscosmos launched Not Soviet hurt ??
maybe they can build a skyscraper in the form of a rocket and rename a nonexistent ship

[slipped]

Quote: Klingon

how much is Roskosmos запустил Not a Soviet hurt ??

Many things. Let's take, for example, last year:

1. Into orbit running and successfully launched a new ERS space platform, manufactured by RSC Energia - the EgyptSat-A satellite. The satellite was launched into the MTR 668 km high.
2. Into orbit to the standing point L2 beyond the orbit of the moon running new astrophysical observatory "Spectrum-RG". The observatory is scanning the celestial sphere. As a platform for telescopes, the new Navigator platform is used, developed at NPO Lavochkin.
3. Into geostationary orbit is running and successfully launched the newest Russian communications satellite of the heavy class "Blagovest" - No. 14L, thus completing the deployment of a military communications group of 4 spacecraft. The satellite is built on the Russian non-pressurized Express-2000 platform with a 15-year lifetime.
4. Into orbit is running and successfully launched a new geodesic satellite, Geo-IK-2 No. 3, for topographic survey of the earth's surface.
5. Into geostationary orbit is running and a new hydrometeorological satellite "Electro-L" No. 3 was successfully launched. The satellite was created on the Navigator space platform with a 10-year active life.

Space platforms "MisrSat A", "Navigator" and "Express-2000" have been developed and built at the enterprises of Roskosmos. In principle, the USSR did not have such a thing. Clear?

* into orbit, into orbit ... * and beyond the orbit, nothing can fly away. Where are the promised Venus-D, where is the lunar rover, where is the lunar station of 2024? phobos-soil and he screwed up. conclusion AMS can no longer build. NASA, Samurai and ESA purged this industry

Where do you get all these probiotic ?!

Any spacecraft moves in space IN ORBIT. Here the cross indicates the position of the Spektr-RG spacecraft at the current moment. He's been there for the third month in parking orbit and is working great.

Quote: Klingon

Where are the promised Venus-D,

Venera-D is absent from the current federal space program until 2025. Today there is only a joint group of scientists from different countries who are working on this project. Its implementation is possible only by the end of the current decade.

Quote: Klingon

where is the lunar rover, where is the lunar station of 2024?

The lunar rover is planned for the Luna-29 spacecraft in the next FKP, while the current one has two lunar landing stations - Luna-25 and Luna-27 with a drilling rig.

[Klingon]

I am aware of Newtonian mechanics
so leave pictures for five-claws. Parking or what but this is the orbit of the earth, not Mars and not Saturn. say Gop when you jump over, but for the time being one conversation is planned.
I'm sorry. there is no trust in Rogozinsky Roskosmos, no trust in Chubais Rosnos. The problem is those who are at the helm and these people are not in their places, one is just a journalist, he would write articles about space, the second is just a huckster

Duc, just for you, five-graders and drawn. But apparently does not reach.

Quote: Klingon

Parking lot or what but this is the orbit of the earth,

Just confirm that before astronomy you still have to grow and grow

The Lagrange point is a libration point - a region of outer space in a system of two massive bodies, in which a third body with negligible mass, in this case "Spektr-RG" spacecraft, does not experience any other forces, except for gravitational forces, from the first two bodies , can remain motionless relative to these bodies. This is not "Earth's orbit", this is deep space. Clear? The spacecraft is moving around this point, which is marked with a cross.

those. they knew that we can and have a nuclear fuel engine !!! ps I'm talking about intelligence
