The best solution for the siting of a spent nuclear fuel and high-level waste encapsulation plant in Switzerland would be to construct it either at a planned deep geological repository or at the Zwilag interim waste management facility at Würenlingen, north of Zurich, national radioactive waste disposal cooperative Nagra said.

Nagra said it compared the advantages and disadvantages of sites for the encapsulation plant and its resulting report will serve as a basis for discussion with the regions.

“From Nagra’s point of view, the best solution would be to realise the encapsulation plant at the deep geological repository or at the [Zwilag] interim storage facility,” Nagra said.
