shut down affected reactors, whether the cracking is' longitudinal' or circumferential.
The petitioner. also requests that-the NRC staff re-license reactors which must be. closed -' due.. to cracking-t based on the assertion that the repair or mitigation' program for-such cracks may negatively affect the configuration and:
ef fectiveness of ' safety systems. The petitioner seeks relief based' on allegations that (1) some VHPs in PWRs-in France, Belgium,-
l 1
' Switzerland, and Sweden are cracking; (2) testing. in France revealed incipient circumferential. cracking of -some VHPs, which' l
could lead to a through-wall break in.the primary pressure boundary Without fulfillment of the leak-before-break' criterion;'and'(3) 9307290170 930607 PDR ORG NRRB PDR

~I this phenomenon could cause the ejection of the control rod drive mes.hanism,- with resulting loss control of the reactor.
The petitioner describes the bases for its request in more detail"~in.
