EDIT: Regarding the moon mission profile: I do not have time to thoroughly evaluate the options right now. But anyone else doing so, please keep in mind: We rolled low. Last time we got a 3-option subvote on a space mission with a roll this low (outer-planets), one of the options was an overambitious trap option. Consider this carefully.
The Lunar Upper Stack Program did roll on the fairly lowish side, with a 17 yeah. Not the sub-10 terrible... but not great at all.
Of the three options:
RLA-3 Minimal Stack: At first glance it seems doable at least. Two potential issues though, for one the current nuclear reactor is only described as kind of stable... which isn't really what I like hearing on a manned vehicle. Secondly one is basically deliberately throwing nuclear reactors on crash courses with the Moon. Sure, the moon isn't inhabitable, but if the reactor core were breached due to impact it would still will leave radioactive areas you won't be able to visit in future, which is not the greatest. Also one would presume that on the political front, parts of the international community might dislike this kind of perceived careless radioactive littering on a place they can see in the sky and might want to visit in future, also it might remind just a little to much of how an ICBM strike would go. So one should probably expect this will be grabbed on by certain parties (like the USA or France) for negative PR against the USSR for a long time to come, considering those places realistically won't be something that can be cleaned up.
Heavy Direct Lander: It would work as such, though obviously developing a super heavy launcher in just a few years is a bit of a rush project. So this will presumably be expensive and there are risks on if the timetable can really be met. Basically the 50 rpy doesn't represent the entire program here, it's that plus the super heavy launcher that is required to be locked in as well then.
Separated Lander: High on technical risk in using orbital rendezvous to the max, but minimal in actual new things that need to be made. Basically this gambles everything on that one can do orbital rendezvous rapidly enough and well enough to assemble a craft to the Moon. Basically if it works one has proven orbital rendezvous as a valid approach going forward for larger assembled projects to various places. Beyond that it will grant no further technical benefit and it has no prospect long term for Moon missions as it's mostly just a flag raising mission. If it works as hoped this is probably the most sure way to get it done quickly as the rockets already exist, you only need to develop the upper stack. For longer term Moon missions the orbital nuclear tug approach already seems like it will work out, so that would basically then effectively be the immediate follow up to this. Where a nuclear propulsion unit can move you between various orbits and it occasionally refuels from where ever it can get fuel, for now this would be only low earth orbit.
As such the first option seems like it might be a bit risky with a reactor design that might not be fully mature by the time it will be used in the mission. Which is perhaps not really what one wants for a high profile manned mission, it would be pretty bad if the nuclear drive developed a major problem or became inoperative during a mission. And seems like it will give one a PR hit for potentially 'kind of' dangerous radioactive littering of an exploration target.
The second option seems like you'd have to really rush through the super heavy launcher development considering the upper stage would already be done in 1982 which is just 3 to 4 short years. Designing a super heavy that quickly would at the least I'd think constrain what kind of designs are possible, anything to innovative is not doable, and it would not be surprising if potential dangerous corners were cut to try and complete it in such a tight time frame. This could lead to spectacular failure problems like seen with our worlds USSR moon mission, where several test launches of their moon rocket all exploded.
The third option gambles that we can master orbital rendezvous, but otherwise only needs to make the lunar landing system as new hardware, launch is fully covered by existing RLA-3 launchers. It's a minimal flag waving system, but hardware wise it's the easiest to complete quickly I'd expect. You would have to develop a follow on lunar system for long term missions, though presumably the orbital tug system would be involved in this which would presumably make things substantially easier. This should then give one more time to develop a heavy launcher for any kind of later missions and more time for the nuclear engine tech to mature for the orbital tug concept before you start moving people around with it.
Putting that all together, you'd think that after docking with space stations for years now, that one could manage some kind of orbital rendezvous at this point. So I'd cautiously suggest that option 3,
Separated Lander might be one of the safest option to proceed with. It doesn't involve experimental technology being pushed in to manned service quickly, and it doesn't need one to rush a super heavy launcher out the door and hope it doesn't have so many problems that your program is delayed for potentially years or explode with a manned capsule on top. Even if something did go wrong with docking in space for the one or other reason, one can safely back out to Earth still and try again later. And even if it never worked one would presumably still be working on the long term Lunar exploration plan, and so one could get to the Moon still at least, even if likely beaten by the USA. But while being beaten by the Americans would be embarrassing and give one some political setback, that could still be recovered if one had a better long term program then the USA did.
If my interpretation is wrong somewhere though, please let me know. To an extent I have to guess a bit on what will happen along each of these paths after all.
PS, the USA using solid rockets for their first stage manned super heavy launcher is kind of scary. This is because if they explode the options for safe excape by the manned capsule will be greatly reduced. Getting clear of the burning chunks of solid rocket fuel would be a lot more challenging and if those hit the parachute of the capsure once it deploys it would obviously be a very bad thing. Also solids are known for causing some rather excessive vibrations compared to liquid rockets, so it might be a bit of a rough ride for astronauts unless they add more things in to dampen the vibrations. So their system is perhaps quick to slap together and it might make a relatively cheap first stage, but it certainly adds further risks to a manned mission.
