MEMORAliDUM FOR:
Darrell G. Eisenhut, Director, Division of Licensing FROM:
Stephen H.. Hanauer, Director, Division of Humn Factors Safety
SUBJECT:
STAFFING OF FIRE BRIGADE My memorandum dated April 9,1981, stated that DHFS does not consider that the Shift Technical' Advisor should be used on the fire brigade.
Since the earlier memorandum, the question has arisen as to who on the plant staff may be assigned fira brigade duties.
-7 l
Appendix R to 10 CFR Part 50 states that the fire brigade leader and at least two brigade members shall,have sufficient training in or knowledge of plant 1
safety-related systems to~ un'derstdid the effects of fire and fire suppressants
'on safe shutdown capability. Use of the Shift Suparvisor on the fire brigade is expressiy forbidden, although the Appendix notes that possession of an operator's license or equivalent knowledge of plant safety-related systems would be sufficient to assure thdt the brigade leader is competent to assess the potential safety consequences of a fire.
It is apparent from the wording in the Appendix that licensees are encouraged to dr.signate licensed personnel as fire brigade leaders. Use of licensed personnel on the fire brigade, however, results in decreased coverage of the control room at precisely the time when control room actions may be required to mitigate the effects of the fire.
Some balancing of resources is necessary.
The resource prob'em is most critical on single-unit sites where the total number of personnel on shift is limited, so we shall discuss the staffing for a singic two reactor operators (RO), two auxiliary operators (non-licensed)per unit. We assume a normal minimum staffing pattern of one Shift Su, and one Shift Technical Advisor for a single unit station.
The Shift Supervisor is properly forbidden to be assigned to the fire brigade since he is in overall charge of the site on a back shift and must be available to supervise site ~ operations. As-noted in my earlier memorandum, the Shift Technical Advisor is required on site so'that teclinical expertise can be readily available tc the control room during an emergency. Thus, the STA should not be assigned fire brigade duties. It is cbvious that the control room operator (operator at the controls) cannot be designated a fire brigade member since he must stay at the control board at all times.
Finally, at least one auxiliary operator should be available to respond to directions from the contrni room in the event his services are needed. In view of the existing minimum staffing p>.t' erns at most operating plants, this t
leaves only the second licensed reactor operator and one of the two auxiliary
- operators available to perform fire brigade duties.

.: rrtil G. Eisenhut Mi 3I" On July 1,1982, in accordance with tiUREG-0737, licensees will be required to
.have a second senior reactor operator on each operating shift, stationed in the control room. On balance, we feel that this 9dividual also could be designated a fire brigade member, since his control room duties could be temporarily assumed by the Shift Supervisor.
-Also by July 1,1982, in accordance with t1UREG-0E54, each shift must have,-in addition to the four licensed and two unlicensed coerators and the STA, a com-municator (who may also provide adainistrative assistance to_ the Shift Supervisor),
one health physics technician and one radiation / chemistry technician, for a total minimum shift complement of ten people exclusive of the plant security force.-
In our view, any of these ten individuals, except for the four mentioned earlier, i.e., Shift Supervisor, Shift Technical Advisor, Control Room Operator, and Auxiliary Operator, are available to serve as members of the fire brigade.
