Commonwealth Edison has identified that literal compliance to Technical Specification 3.7.0.1 cannot be achieved due to a plant modification which was performed during the Unit 1 Refueling Outage. Durir,g the Unit 1 outage, the Head Spray line and valves were removed as part of the IGSCC mitiga-tion program. . Commonwealth Edison notified the NRC of the intent to perform the modification in the Unit 1 IGSCC Inspection Plan submitted on Junc 9, 1989, 1 however, failed to submit the associated Technical SpecificcMon to allow for NRC issuance of the amendment prior to startep., This was identified during a review of Technical Specification amendments to be incorporated in the Quad Cities' Technical Specification Improvement Program. Commowealth Edison is performing an investigation on the root cause of the event. Appropriate corrective actions will be implemented based on the investigation results.

Current Technical Specification 3.7,0.1 requires that all isoletion valves listed on Table 3.7-1 be operable during power operation. Head Spray Valves H0-1001-60 and 1001-63 w1re included in the listing of isolation valves.

Due to the removal of these valves, literal compliance cannot be achieved.

Technical Specification 3.7.0.2 states that in the event an isolation valve becomes inoperable, reactor power operation may continue, provided at least one valve in each line is in the mode corresponding to the isolated condition. The remaining piping on the head spray system (reactor side) is fitted with a blind flange,.thereby the intent (not the letter) of Specification 3.7.D.2 is met.

The current configuration is thereby consistent with the philosophy of providing the isolation of the reactor pressure boundary to prevent a unisolable release pathway 1n the event of an accident. The modification was tested to ensure integrity of the installation. Commonwealth Edison therefore request that a temporary waiver of compilance be granted to allow the restart of Unit 1. Unit

.startup 1s currently scheduled for Saturday, November 18.
