Calvert Cliffs Nuclear Power Plant Unit Nos.1 & 2; Docket Nos. 50-317 & 50-318 Safety Parameter Disolav System Ouarterly Report
REFERENCE:
(a) Letter from Mr. F. J. Miraglia (NRC), to Mr. J. A. Tiernan (!!G&E),
dated September 30, 1986, Extension of Parameter Display System Operational Deadlines Gentlemen:
In granting our request for an extension to the operational deadlines for the Safety Parameter Display System (SPDS), Reference (a), you required us to provide quarterly progress reports beginning January 1,1987.
Attached is a report covering the progress of the SPDS project for the fourth quarter of 1987. As you requested in Reference (a), we are providing:
1
- our progress in establishing the fully operational SPDS for each unit, l
- our status of the SPDS software development and testing, and
- the identification and status of the critical path item.
Should you have any questions regarding this matter, we will be pleased to discuss them with you.
Very t,ruly yours, W

ATTACilMENT SAFETY PARAMETER DISPLAY SYSTEM PROGRESS REPORT 4TIIQUARTER 1987 A.
SPDS Pronress 1.
Integration of the plant computer with the data acquisition system resulted in design changes that will be incorporated in the months ahead. The changes are primarily associated with the state of contacts.
2.
The power supply to the computer room air conditioning system was investigated. An alternate diesel-backed power supply will be provided.
Preliminary engineering is underway.
3.
An SPDS Alarm manual was completed and distributed for comment.
4.
A process for controlling future design modifications was established. The process will involve input from Operations, Nuclear Training, Computer Maintenance, and Design Engineering.
5.
SPDS Operator training is continuing. SPDS training sessions are scheduled for the 1988 requalification training program. Training has already been conducted during the two previous requalification sessions.
6.
A documentation package supporting our ongoing verification and validation program is being prepared. A key element - the regulatory requirements matrix - was completed.
II.
Slatus of Software Development and Testina 1.
Real-time video trending and x-y plot capability were successfully tested prior to shipment of the Unit One plant computer. These functions were installed in the Unit Two computer.
2.
Unit One plant computer was configured to operate in parallel with the Unit Two plant computer. This allowed Unit One's computer to receive real-time i
data from Unit Two's data acquisition system facilitating Unit One's site acceptance testing.
3.
Operations has judged SPDS response times acceptable. More work will be done concerning trending, I
C.
Critical Path item Software changes based on the results of on-site testing continues to be the critical path. We are progressing on schedule to meet our operational deadline of July 1, 1988, for both units.
