If all of the countries now planning to go nuclear also handle their own fuel cycles, the proliferation risk could skyrocket.

Newcomers to nuclear power could be reluctant to put their fuel cycles in international hands if existing nuclear powers, such as the us, Russia and the UK, continue to control their own.

GNPS begins to implement the 18-month fuel cycles from the initial annual reload at cycle 9, thus the initial core thermal hydraulic design is not valid any more.
