Tritium Removal Facility
WHY TRF IN ROMANIA ?




Rising the tritium level in heavy
water from CERNAVODA NPP (>32
Ci/kg in 2005)
Environment and human
contamination risk
New requirements in 2007 after
Romania join EU
Tritium application for fusion
technologies – Romania can offer
tritium for fusion reactor
