Yeah, that's the original document; sorry I didn't provide a proper link before.I'm not sure what "Saturn Ia" could refer to; my guess would be a Saturn I with a Centaur (S-V) stage on top...
Somewhere buried on my hard drive is the JIMO final report. If I find it (it was on an obscure JPL website), I will post it here. Buried deep in the report is the price tag, which was over $20 billion.
My guess:I: Saturn A-1 (S-I + Titan I 1st stage + Centaur)Ia: Block II Saturn I (S-I + S-IV + Centaur)II: Saturn C-2III: An eight-F-1 Nova
1-What they should have done was have some overlap with manned space flight and use the exploration program to fund the reactor development.2-In this case the actual cost of the mission ends up much lower then 20 Billion as most of the R&D costs are amortized elsewhere.3-But CxP was poorly executed and the HSF and unmanned parts of NASA were put at odds with each other which should not have been the case.
Here is the Prometheus Final Report.Notice that buried on page 178 is the fun stuff:Total $16.317 BILLIONLaunch System $5.161 BILLION
Do I read pg.179 correctly that NASA spent almost a $half-billion before cancellation? $464 million / 775 FTE-man-years is $600 thousand per FTE-man-year. How does that make sense if almost all the work was (presumably) analysis, hence only salaries + benefits, not metal-bending?
The half billion in development is correct. A lot of that was spent on developing rad-hardened components.
Did any usable hardware come out of the 0.5 B or was it all R&D?

A lot of that was spent on developing rad-hardened components.Which are still needed for JIMO's spiritual successor, JEO, as the real hard radiation is from the Jovian magnetosphere, not any reactor. Indeed, the cost of the super-rad-hard components is part of the reason why the JEO project is looking to be at death's door (in addition to using nearly all the Plutonium on the planet and having an obscenely long approval-to-science timeline).
