U.S. Regulators Find No Need to Hasten Spent Nuclear Fuel Transfers

U.S. reg­u­lat­ors have op­ted against or­der­ing the ex­ped­ited trans­fer of spent atom­ic fuel from above-ground pools to dry casks, the As­so­ci­ated Press re­ports.

The Nuc­le­ar Reg­u­lat­ory Com­mis­sion de­cided to abide by an in­tern­al ad­vise­ment to cease ex­plor­ing the idea of re­quir­ing atom­ic en­ergy plants to speed up the re­mov­al of used fuel from stor­age pools to met­al and con­crete con­tain­ers, ac­cord­ing to a Fri­day com­mis­sion memo.

“The com­mis­sion has ap­proved the staff’s re­com­mend­a­tion that this … activ­ity be closed and that no fur­ther gen­er­ic as­sess­ments be pur­sued re­lated to pos­sible reg­u­lat­ory ac­tions to re­quire the ex­ped­ited trans­fer of spent fuel to dry cask stor­age,” states the memo by Rochelle Ba­vol, act­ing com­mis­sion sec­ret­ary.

A num­ber of U.S. law­makers and act­iv­ists have cri­ti­cized the nuc­le­ar en­ergy in­dustry’s long­stand­ing prac­tice of keep­ing large quant­it­ies of highly ra­dio­act­ive atom­ic ma­ter­i­al in lightly pro­tec­ted stor­age pools. Their con­cern is that wa­ter sur­round­ing the used fuel could es­cape its con­tain­er and lead to the dis­pers­al of harm­ful ra­di­ation in­to the en­vir­on­ment in the event of an earth­quake, flood or ter­ror­ist at­tack.

Last year, com­mis­sion staff con­cluded that mov­ing spent fuel to dry cask stor­age would not res­ult in safety im­prove­ments great enough to war­rant the ex­tra fin­an­cial cost that would come with im­ple­ment­ing the meas­ure.

Bill Dean, Nuc­le­ar Reg­u­lat­ory Com­mis­sion north­east re­gion­al ad­min­is­trat­or, in an in­ter­view said the reg­u­lat­or had de­term­ined that both dry casks and pools were “ad­equate stor­age pro­cesses for spent fuel, and there is not a sig­ni­fic­ant safety be­ne­fit to re­quir­ing full trans­fer to dry cask stor­age.”

U.S. Sen­at­or Bernie Sanders (I-Vt.) was one of five sen­at­ors to write to the com­mis­sion’s head in re­cent weeks to warn against eas­ing safety and se­cur­ity reg­u­la­tions for moth­balled ci­vil­ian re­act­ors.

“We are one nat­ur­al dis­aster, mech­an­ic­al fail­ure or ter­ror­ist at­tack away from a dis­aster,” Sanders said in a Tues­day state­ment. “If the NRC will not change the rules, I will con­tin­ue to work with my col­leagues to change the rules through le­gis­la­tion.”

Cla­ri­fic­a­tion: This art­icle was mod­i­fied after pub­lic­a­tion to cla­ri­fy the po­ten­tial for ra­di­ation leaks.

Donald Trump "nearly quintupled the monthly rent his presidential campaign pays for its headquarters at Trump Tower to $169,758 in July, when he was raising funds from donors, compared with March, when he was self-funding his campaign." A campaign spokesman "said the increased office space was needed to accommodate an anticipated increase in employees," but the campaign's paid staff has actually dipped by about 25 since March. The campaign has also paid his golf courses and restaurants about $260,000 since mid-May.
