P.02 Citizens Urging Responsible Energy ".

J September 16, 1994 Ivan Selin, Chairsian US Nuclear Regulatory Commission Washington, D.C. 20$55 via Fax: (301) 504-1672 Esar Chairman Selin As you are avare, the Pilgrim Nuclear Power Station automatically shutdown on August 29, 1994. This is the fourth unplanned shutdown this year. While various malfunctions associated vith the shutdown remain under investigation, it is now apparent that the plant's main generator ves seriously damaged. Boston Bdison originally said there was "no damage to any of the equipment."

However, at a press conference last Monday, the company confirmed that Pilgrim will remain off line for up to four months to complete up to $6 million in repairs.

Our purpose in writing is to inform you that two anonymous sources have stated that Boston Edison is aware Have you been l

l that the core shroud at Pilgrim is cracked.

noticed of such findings, or has past NRC inspection activity identified any core shroud crack indications at Pilgrim 7 Clearly the NRC views the subject of core shroud cracking  !

with great concern since you have issued Generic Letter 94-03, "Intergranular stress corros,on cracking (IGasc) of core shrouds in Boiling water Reacto rs " on July 25, 1994  !

gg notice g onnortunity Igg nubile commenIni *because fact, of j e urgent nature of the actions requested.=

Federal Register, Volume 59, No. 155/ Triday, August 12, 1994 says, "The NRC determined that the need for licensees to tuplement the reauested actions quickly made it necessary  :

1 to :,ssue this generic letter immediately."

In view of Pilgrim's unexpected lengthy outage and the ,

emergent nature of this issue, we feel it vould be prudent for the NRC to novo up the schedule for Pilgrim's core shroud inspection. Have you considered this action?
