In accordance with Beaver Valley Unit 2 License Condition 2.F, Beaver Valley's Nuclear Group isdministrative Manual (NGAM) 5.1,
" Report Requirements", NGAM 3.5,
" Fire Protection" and NRC Generic Letter 86-10, the following Special Report is submitted.
The Nuclear Group Administrative Manual requires a Special Report if Fire Protection Instrumentation is inoperable for greater than 14 days.
This report is being issued due to an event where a fire detection instrumentation surveillance was not performed within its required frequency.
In the fall of 1989, a change in the NFPA code was made that allowed smoke detectors to be tested on a twelve month frequency instead of the former six month frequency.
In 1991, Beaver Valley updated its smoke detector testing procedure to reflect this change in the code.
However, due to inadequate review, station ptrsonnel failed to realize that the moke detector surveillance procedure also tests eight ultra-violet flame detector tests were performed on 2/4/91 and 10/25/91.
- his resulted in a failure to test the ultra-violet flame detectors via separate procedures with different frequencies.

- There are no safety implications due to this event.
.The ultra-violet flame detectors are-used to provide an early warning indication function only.
A separate system of Heat
- Actuated _ Devices (HAD) is installed.in the same areas as the flame detectors.-
-These HADs provide both control room indication of a -- fire and an automatic actuation signal' to the
' installed CO2 fire suppression system.
Very truly yours,.
