Control Room Design Review (CRDR)
Control Switch Relocation R.E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Stahle:
On July 14, 1987 Rochester Gas and. Electric submitted to you a Supplemental Report of our Control Room Design Review (CRDR) effort at the Ginna Nuclear Power Plant.
That report, among other things, described our response to a number of HEDs that involved relocation of circuit breaker control switches on the main control board.
- Further, the report declared that the control switch relocation work would be completed by the end of the 1988 refueling outage.
Concurrently, LER 87-001 further committed RG&E to a long term plan to reconfigure the station offsite power supply system.
This power system reconfiguration is presently in the design stage and will be installed in 1989.
The new design requires additional circuit breaker control switches to be added to the main control board in the area intended to be modified to satisfy the require-ments of the CRDR.
In consideration of operator training, it is better to modify the control board once and retrain the operators only one time rather than to introduce two modifications at different times and potentially create confusion with the operators.
It is our intent then, to delay the modification for the CRDR until such time as the station offsite power supply system design is installed.
The controls for the reconfigured offsite power supply will receive human factors review to assure that no human engineering deficiencies are introduced by the modification when integrated with the control modifications of the CRDR.
The modifications which address both the existing CRDR commitments and the offsite power reconfiguration will be completed during the 1989 refueling
-outage.
