Dear Mr. Crutchfield:

An RG&E letter dated August 3, 1983 provided the Company's schedule for installation and operation of the Safety Assessment System (SAS).

The current vendor schedule for delivery of the Ginna Station SAS and the required plant process computer system is mid March 1985, which coincides approximately with the beginning of the 1985 refueling shutdown.

However-, after review-ing the vendor progress in system software development, RG&E has concluded that the actual delivery schedule will slip from three to six months.

This delivery schedule will preclude system installation during the 1985 refueling outage as previously planned.

Although every effort will be made to compress the current schedule to effect a

1985 installation, a realistic review of the rate at which tasks are being completed leads RG&E to now project system installation during the 1986 refueling outage with full operational status one year thereafter.

It should be noted that the system is expected to be functional when installed.

A complete test of the system hardware and software will be performed at the vendor's plant prior to shipment.

However, a system this complex may require ten to twelve months of operation on site before full capability is achieved.

Since the delay of one year in installation will allow more extensive testing and operator training at the vendor's facilities prior to delivery, the "shakedown" period may be reduced.

However, it is impossible to quantify this potential reduction.

The slippage in schedule has resulted from four factors, the vendor's underestimate of the extent of system operating software to be developed, the incorporation of this software into a standard "product line", a shortage of personnel familiar with th

hardware operating

systems, and the vendor's underestimate of applications software requirements.

RGaE has closely monitored the vendor's technical activities and has brought about changes in project management intended to accelerate the schedule.

RGGE management has also formally notified the vendor of the serious consequences of the additional slippage now anticipated.

RG&E has also evaluated alternatives to continuing the project with the current vendor.

However, the results of this study indicate that changing vendors would involve longer delays and greater costs than those anticipated with the current vendor.

In view of the facts outlined above, RG&E requests that the SAS implementation dates for Ginna Station be modified to show installation complete by June 1986 and operational status by June 1987.

e y truly yours, er W. Kober
