Caution Is Needed in Operating and Managing the Waste of New Pebble-Bed Nuclear Reactors

“…26 Five canisters are to be stacked on top of each other, in rows of eight, with expected storage time of 50 years. 27 With the openair ventilation cooling scheme proposed, 28,29 chloride-induced stresscorrosion cracking of the canister body can become a problem, exacerbated by salt mists from the coast; fire hazards need to be mitigated in such a dense storage site; and the 2-cm-thick canister wall, made from 304L stainless steel, can be penetrated by rifle bullets. These canisters do not provide adequate protection against credible hazards.…”
