SUBJECT:
Reply to a Notice of Deviation J. M. Farley Nuclear Plant NRC Inspection of December 11, 1988 - January 10, 1989 RE:
Report Numbers 50-348/88-32-01 50-364/88-32-01
Dear Sir:
This letter revises Alabama Power Company's February 21, 1989 response which-refers to the deviation cited in the subject inspection reports which state:
"The following deviation was identified during a Nuclear Regulatory Commission (NRC) inspection conducted on December 11, 1988 - January 10, 1989..
.FSAR Sections 9.4.1.2 and 9.4.1.3 state process radiation monitors are provided at the control room normal fresh air intake for the control room air conditioning and filtration system. Receipt of a high radiation signal by a monitor will cause an alarm to sound in the control room and closure of isolation valves in all ducts penetrating the control room boundary, thereby isolating the control room.
Contrary to the above, on December 23, 1988, during a routine control room ventilation isolation surveillance test, the NRC inspectors identified that receipt of a high radiation signal by the process radiation monitors closed the control room isolation valves (dampers) but would not sound an audible alarm within the control room. However, lights on the balance of plant panel and on the main control board indicated that the valves (dampers) changed from the open to the closed position."
Reasons for Deviation This deviation was caused by personnel error in that (1) the FSAR system description did not reflect the approved design, and (2) the startup test engineer failed to note the' discrepancy when developing the system test procedure.

U. S. Nuclear Regulatory Commission April 28,1989 Page 2 Evaluation on a high radiation signal from either control room air intake radiation monitor, ventilation automatically isolates without operator action.
Therefore not having the alarm is not a safety concern. The FJP architect / engineer evaluated this condition and concurred that the requirement for an audible alarm may be removed from the FSAR. However, based on further management review, an audible alarm would be a desirable enhancement. Hence, an audible alarm has been installed.
Corrective Action Taken and Results Achieved An audible alarm was installed.
l Corrective Steps To Be Taken To Avoid Further Deviations Design change controls have been upgraded so that a more detailed review is performed for these changes and their associated FSAR changes.
Date of Full Compliance l
