Hi, sorry to say, but that's actually a myth. The US never did and never seriously planned to make weapons from commercial reactors. We make weapons with special graphite or heavy water moderated weapons production reactors. The MSRE was shut down because: * The existing major industrial and utility commitments to the LWR, HTGR, and LMFBR. * The lack of incentive for industrial investment in supplying fuel cycle services, such as those required for solid fuel * The overwhelming manufacturing and operating experience with solid fuel reactors in contrast with the very limited involvement with fluid fueled reactors. * The less advanced state of MSBR technology and the lack of demonstrated solutions to the major technical problems associated with the MSBR concept. ref: WASH-1222 https://doi.org/10.2172/4372873 https://doi.org/10.2172/4372873
