-.n Sinca this plant modification has caused spurious reactor trips, _ , _ _':: ~
wa egr:e that it is prudent not to require the modification to """ ~ be op; roble until this problem is resolved and oppropriate h" .._.. c fractive' action is taken. In the interim, to avoid spurious scrcms, while resolving the problem, the licensee has stated ""~ in a July 31,1984 letter that it intends to simply jumper out the low pressure scrom logic, thus isolating this installed modifi. """ cotion from the plants reactor protection system. We find this occcpt:ble. The NRC willinspect these jumpers to assure that : == thry h:ve been properly installed. _ The Ccmmission has determined that a timely application for the proposed change was mode and that exigent circum- . . . _ . _
~~
stancss do exist and were not the result of any fault of the li. c:nssa. The exigent circumstances result from the fact that the tims is needed to confirm the cause of the problem and to establish on adequate basis for any proposed changes in the """ scram sstpoint. By requesting on exigent review, the licensee L. is avoiding a possible emergency amendment request in the E. evsnt that Unit 2 were to incur o shutdown in the immediate 2. . .m . . futura and this new scram capability would not allow the unit to rsstsrt due to odditional spurious scroms. Following on initial review of this 'opplication, the NRC staff hos m:da o proposed (preliminary) determination that the re-qusstsd amendment involves no significant hozords consider-otion. Under NRC regulations, this means that the proposed omandment does not involve a significant increase in the prob bility or consequences of an occident, would not create . tha psssibility of a new or different kind of on occident, or in- gg:u. .. A* volve o significant reduction in a sofety margin. The Commission h'as determined that due to exigent circum- <.=- stancss there is not sufficient time to publish notice in the F,.e; "= " deral Regn.tgr for public comment before issuance of the pro. possd cetion.
- If tha proposed determination that the requested license omendmant involves no significant hozords consideration be- m "'
1 cemis final, the stoff will issue the amendment without first ==x-.. offsring en opportunity for o public hearing. An opportunity for o hearing will be published in the Federal Register of a lo-t r dots and any hearing request will not delay the effective , :. data of the amendment. '

If the staff decides in its final determination that the amend. e = ment doss involve o significant hozords consideration, o no- p. tice of opportunity for a prior hearing will be published in the L. Federal Register and, if a hearing is granted, it will be held 4"
