The ueficiency conc 2rns General Electric's failure to provide seismicall'. and envircr.antall) qualifted instruments fcr use in nuclear safe: systems in the Calance of Plant (30P) Power Generation Centrol Cemplex (PCCC).

Currently, General Ele.:ric is evaluating the instrumen:ation in question to determine the corrective actions necessary to meet design requirements for safety related POCC mounted instrunents. These actions include the qualification of already purchased equi l.nent or the pro-curencnt of replace =ent instrumentation that meets qualification specifications. The evaluation of safety i=plicatiens associated with this deficiency will not be conpleted until all corrective actions are identified. The reportability of this ceficiency will be determined at tha; tit'2.
