Steve Aftergood has the unclassed exec.summary of the JASON RRW study. As far as I know, the Post’s Walter Pincus was the first to report on it. Jon Fox from GSN also has a good article on the report.

Bottom line seems to be that the idea of “certifying a new warhead w/o testing” is still in the “not gonna happen” category, at least for now.

It is worth noting that former NNSA head Linton Brooks said at the CEIP conference a few months back that the RRW

will put the final nail in the coffin of nuclear testing because in the next term when we take a serious look at the Comprehensive Test Ban Treaty, the technical argument against ratification will be taken away by a concept that drives any question of the need to test for future problems out.

Just saying.
