I just received my annual TCP-1 letter from LLNS and a summary of the LLNS Pension Plan. Looked in pretty good shape in 2013. About 35% overfunded (funding target attainment percentage = 134.92%). This was a decrease from 2012 where it was 51% overfunded (funding target attainment percentage = 151.59%). They did note that the 2012 change in the law on how liabilities are calculated using interest rates improved the plan's position. Without the change the funding target attainment percentages would have been 118% (2012) and 105% (2013). 2013 assets = $2,057,866,902 2013 liabilities = $1,525,162,784 vs 2012 assets = $1,844,924,947 2012 liabilities = $1,217,043,150 It was also noted that a slightly different calculation method ("fair market value") designed to show a clearer picture of the plan' status as December 31, 2013 had; Assets = $2,403,098,433 Liabilities = $2,068,984,256 Funding ratio = 116.15% Its a closed plan with 3,781 participants. Of that number, 3,151 wer...

I agree it could be in the past the levels were arbitrarily set, but any new levels chosen should incorporate what is now known.
The cataract consideration is not the only case of this, as there could be other cases of non-stochastic harm, where cancer is not the only consideration.
Also some individuals are "radiosensitive" in that they lack the the normal genes which protect for cancer, provide hormesis, or lack healthy immune systems. This means certain subpopulations of the overall population may have individually greater risk that could be identifiable by genetic testing, meaning they could have stronger grounds to win a court case that their particular cancer is radiation induced.
Certain individual blood cancers are also more easily induced by radiation, even at low doses, than cancer in general so it also would be the case that any hormesis effects would not prevent a higher rate of those occuring.
Finally the levels in question may be simply too high for hormesis to occur or for radiation to provide a net population benefit, even if it is true in some way.

There are some concerns that a much more modern and presumably safer reactor of a somewhat similar type (both use sodium with no containment structures, but the newer one is a fast reactor with HALEU) which is being constructed in Wyoming may also exhibit problematic failure modes, since approvals have been rushed through:

This brings up how the narrative about safety obscures the other historical reasons these technologies have not been pursued.
