i-NRW Panar.zM AT 0Y5733 muur Q.Ab George Ritter ca.lled me today to inform me of the identification of a new problem with the reactor vessel internals at Oysser C:eek.

During recent inspection of the core shroud support ring

• a defect was found.

The defect was removed and examined metallurgically.

The initial results of this examination indicate evidence of stress corrosion.

Jersey Central and General Electria: nre reviewing the significance of this finding and its possible impli-cations.

A schedeled briefing on the vessel problems (to have been held on May 24th) has been postponed for at least a month; a scheduled ACRS review of these i.

problems will be postponed similarly.
