I suspect that this project would not get funding in 2016-2025 Federal Space Program because Russian Space exploration strategy choose Moon first approach
Quote from: fregate on 07/05/2015 05:38 amI suspect that this project would not get funding in 2016-2025 Federal Space Program because Russian Space exploration strategy choose Moon first approach I was wrong - it survived sequester, but sill unclear what exactly would be delivered in 2025. Stand by for tenders. The good news - it still a joined project by ROSKOSMOS and ROSATOM
May be the interagency project helps saving it? May be Rosatom is funding the bulk of the project?Sent from my Classic using Tapatalk

Roscosmos announced a next tender of R&D program TEM (Joint project of Roscomos and Rosatom)Link https://rns.online/military/Roskosmos-zakazal-razrabotku-yadernoi-energoustanovki-dlya-zvezdoletov-za-38-mlrd-rublei-2016-06-24/ (in Russian)PRICE TAG RUB 3,811,142,400For Comparison price of producing and supplying of 3 LV Soyuz 2.1A RUB 3,325,110,690i.e. cost of this stage (2016-2018) is approximately equal to the cost of three and half launchers Soyuz 2.1A
The article says RUB 38B. Aren't you missing an OoM in your price tag?
Thanks Fregate. Launch is in 2020 on an Angara-A5. Mass is 20,290 kg with deployed dimensions of 53.4x21.6x21.6 m.
I hope this comes to fruition. It holds the most promise of anything currently in the Russian space industry of making a contribution to global space exploration. Nothing against continuing programs like Soyuz -- it's still valuable to continue capabilities, but they're not new contributions.
What would be the delta-v of this stage with no payload?

I didn't say this nuclear propulsion program was the only thing that might contribute something new, I said it "holds the most promise".As such, I was making a fundamentally subjective judgement. In my opinion, the nuclear propulsion program holds more promise of making a substantive contribution than the PTK NP.

Quote from: gosnold on 06/26/2016 10:19 amWhat would be the delta-v of this stage with no payload?It is quite difficult even to guess/estimate without knowing values of Specific Impulse, thrust (to estimate gravity losses) and mass of propellant
I don't read Russian but I see in the pictures something about "70 km/s" which I think is the Isp and a mass of 20290kg. So it seems all that's missing is the mass of propellant, and maybe it's in the picture. If you can make sense of them, could you post a translation?

Abstract: The design-ballistic analysis of the effect of parameters of elliptical basing orbits of the reusable interorbital tug based on the nuclear power plant and electrorocket propulsion system of megawatt-class safety and efficiency of its use in the program which provides heavy cargo traic to geostationary and near-Moon orbits has been made. It is shown that in comparison with the option of traditionally considered circular radiation safe orbit of altitude Hcir = 800 km the use of high elliptical basing orbits allows to reduce by approximately two orders the duration of staying in the single light of the tug itself and the launched payload in the area of intensive contamination with anthropogenic space debris. In this case the total weight of the payload to be delivered by the tug to target orbit can be signiicantly increased during its life cycle, as well as the xenon consumption per unit of weight of the payload to be delivered can be reducedseveral times.Key words: reusable interorbital tug, nuclear power plant, electrorocket propulsion system,basing orbit.

Ekipazh, on the other hand, is a top-secret military project assigned to KB Arsenal by the Ministry of Defense in 2014. It uses a much more modest thermionic nuclear reactor and may have something to do with space-based electronic warfare. There does not seem to be a connection between the two projects.Anyway, thanks for posting that link. The pictures are definitely interesting because even the 1-megawatt reactor has become shrouded in secrecy in recent years. I wonder where the they come from. No source is given by the person who posted them.
1. What will launch the thing ( Angara A5 ?) .2.Also why they even develop this thing without specific mission for it i.e a JIMO type mission or a manned/cargo mars mission ( but 1 MWe would not be enough ) here is a recent NASA presentation on the subject http://fiso.spiritastro.net/telecon/Mason_8-19-20/ .3. Do you have any information on the reactor itself ( like cooling system , mass , ALPHA and electric conversion system ) .
Court documents also reveal that KB Arsenal signed a contract (called TEM-Arsenal) with the Khrunichev Center on July 1, 2015, for work on an orbital demonstrator identified as 327AN30-TEM-1 to be launched by the Angara-A5 rocket. According to the documentation, KB Arsenal initially studied a 140-kilowatt version of the demonstrator, but in May 2016 was ordered to upgrade this capacity to 500 kilowatts, one resulting problem being that it exceeded the launch capacity of the Angara-A5 by about 1.5 tons.[11] Roscosmos chief Dmitri Rogozin recently said that it has not yet been decided if it is necessary to build a 500-kilowatt interim version before moving on to the one-megwatt version.[12]The one-megawatt TEM project appears to have been affected by the significant budget cuts that hit Russia’s Federal Space Program for 2016–2025, approved in March 2016. At that point, Roscosmos ordered a series of studies that would have resulted in the launch of a demonstrator satellite no sooner than 2025.[13] KB Arsenal was assigned to one of those studies (called “Yadro” or “Core”) in November 2017. This was aimed at defining possible missions for TEM by November 2018 and would have to result in determining technical specifications for actual flight vehicles (with a reactor capacity ranging from 100 kilowatts to one megawatt) to be developed under a follow-on effort called Nuklon.[14] An indication that the full-scale one-megawatt TEM may not fly for at least another decade came in a recently released Roscosmos tender, which calls for completing ground-based infrastructure for TEM at the Vostochny Cosmodrome no earlier than 2030, a staggering 20 years after the project was initiated.[15]
Electronic warfare is also one of the missions studied by KB Arsenal for the one-megawatt TEM project under the previously mentioned Yadro research program in 2017–2018. As is known from the tender documentation released for Yadro, Roscosmos ordered participants in the tender to look at EW payloads capable of interfering with “control, intelligence, communications and navigation systems.” KB Arsenal proposed an EW payload with a maximum mass of five tons and a power source generating between 100 and 1,000 kilowatts. The dimensions of the EW antenna were given as 10 x 2.5 x 0.4 meters in “transport mode.” The only other missions in Roscosmos’ specifications for Yadro were remote sensing, directed energy transfer using lasers, communications, and interorbital transport of payloads.[33] The solar system missions widely advertised for the one-megawatt TEM in the early years of the project were notably absent from the objectives.All this, along with the fact that the one-megawatt TEM project has become increasingly cloaked in secrecy in recent years, is a possible sign that it is being at least partially militarized. It is worth noting in this respect that training sessions on handling hazardous radioactive materials that were organized last year for both Roscosmos and KB Arsenal specialists were described as being related to the use of “nuclear energy for defense purposes.”[34]
The demonstrator reactor will 1 MW electric or thermal ?
The fact that the images posted on the NK forum were made in a section of the Army 2020 exhibition that was off limits to the general public would tend to confirm the latter speculation.
There is a thread devoted to the 1 megawatt TEM here:https://forum.nasaspaceflight.com/index.php?topic=37957.0Perhaps it's better to continue this discussion there.Again, Ekipazh is a different project.[zubenelgenubi: I split/merged these posts from here to there.]
Don't get me wrong, it would be incredible if they can actually produce and launch it, but what would you even do with 1MWe on an outer planets probe?
The power is mainly for the electric propulsion .Probably no more than few 10's of KWe are available for the science payload and communication (which is still a LOT ) .The proposed NUKLON is basically JIMO on steroids .

Those are in the hundreds of kW range. Got to be interesting applications for that such as finding smaller moons, characterizing ring particles, etc.Quote from: RON_P on 09/17/2020 03:05 pmThe power is mainly for the electric propulsion .Probably no more than few 10's of KWe are available for the science payload and communication (which is still a LOT ) .The proposed NUKLON is basically JIMO on steroids .Once the probe is in orbit that frees up a lot of power.
As i said JIMO on steroids ( JIMO 200-250 KWe vs NUKLON 1 MWe) .
They can't use more than 200 KW with only four ion thrusters.
but they can
A space tug implies it would push something. This looks like it would have to push something with the reactor end, as the ion thrusters are at the opposite end. Weird.
Wait this is new so Nuklon was downsized from 1 MWe to 500 KWe ?
I heard that first prototype will be 200 KWe. I also heard that metal is already being bent for it as we speak.
My understanding is that all the hardware present at Arsenal at that time had been produced on the basis of a government contract signed between Roscosmos and the Keldysh Center on November 18, 2016. KB Arsenal acted as a subcontractor to the Keldysh Center under that contract.
I presume the 200 kW version you're referring to is the one recently proposed by the Keldysh Center and discussed here in Reply 53.
MOSCOW, May 22. /TASS/. The first mission of Russia’s nuclear-powered transport and energy module, Zeus, will last 50 months, Roscosmos Executive Director for Long-Term Programs and Science Alexander Bloshenko told reporters on Saturday."The combined duration of the mission is 50 months," he said during the New Knowledge forum.He went on to say that the first flight has been scheduled for 2030."Together with the Russian Academy of Sciences, were are now making calculations about this flight’s ballistics and payload," he said.According to Bloshenko, the space tug will first approach the Moon, where a spacecraft will separate from it. After that, it will head to Venus to perform a gravity assist maneuver and deliver another spacecraft. Then, it will depart towards Jupiter and one of its satellites.Last December, Russia’s space corporation Roscosmos and design bureau Arsenal signed a contract for developing a preliminary project of a nuclear-powered space tug Nuklon, to be used in deep space missions. The contract signed on December 10 is estimated at more than 4.17 billion rubles. The delivery date is July 28, 2024.

...And the latest visuals of #Russia nuclear-electric space dreadnought emerge at a military trade show... but its mission described as delivering scientific instruments to the Moon and planets. MORE PICS, CONTEXT: http://www.russianspaceweb.com/tem.html#2021_07
So looks like missions to the Moon, Mars, Jupiter and "other bodies" are proposed.
Borisov said that Russia will use a nuclear tug in a joint project with ChinaMOSCOW, 26 April. /TASS/. The nuclear tug "Zeus" will be involved in a joint project with China of the international scientific lunar station. This was announced on Wednesday by Director General of Roscosmos Yuri Borisov at the educational marathon "Knowledge. First".“We have a nuclear tug called Zeus. We are going to put it into practice by 2030. This is one of the products that will help in the expansion of the moon, we are going to use it in a joint project with China,” Borisov said.According to the head of Roskosmos, the tug will allow large objects to be delivered from near-Earth to near-lunar orbit.According to Borisov, China is interested in Russian rocket engines.“We have an agreement with China on the creation of an international scientific lunar station, we are actively working. They are interested in our competencies in engines, they really want to get them and figure out how they are made in order to repeat them,” Borisov said.According to the head of the state corporation, the Russian Federation has such relations with India, Roscosmos helps in organizing the first flight of a manned spacecraft into orbit.At the end of 2022, Roscosmos announced the signing of a program for the development of cooperation in space activities for 2023-2027 with the Chinese National Space Administration (CNSA). In addition, the governments of Russia and China signed a cooperation agreement on the creation of an international scientific lunar station, the roadmap of which was presented in June 2021. According to the information provided, the construction of the station should be fully completed by 2035.The federal educational marathon "Knowledge. First" is held from 24 to 26 April at the Central Arena in Moscow, as well as at venues in Yekaterinburg, Arkhangelsk, Pyatigorsk and Lugansk.

Was expecting this. China is working on a 1MW nuclear reactor for space purposes. This is one area where they can profit a lot from cooperating with Russia, speeding things up considerably.For Russia, I guess this means Zevs can fly after all.
