ZIMMER NUCLEAR PCWER STATION -
UNIT 1 - APPEAL FRCM STAFF FIRE BRIGADE MANPCWER REOCIREMENT
Dear Mr. Denton:
We have reached an impasse with certain members of the NRC Staff regarding the size of the plant fire brigade.
It is our position that a four man fire brigade is sufficient in size for the reasons given belcw.
We are, therefore, appealing to you for relief from the rigid staff position.
An extensive fire hazards analysis report (" Fire
( ) Protection Evaluation Report") was prepared for the Zimmer Plant and submitted to the NRC.
This report included a logical review of each plant area, the combustibles located in the area, fire resistant barriers around the area, and protection systems in the area.
Several conservative assumptions were made in the analysis with respect to fire loading and fire potential.
In this report, it was shcwn that areas of the plant having a significant quantity of combustibles, the potential for ccm-bustibles, or, areas that contain safety related equipment are prctected by automatic fire protection systems.
Added assurance that inadvertent accumulation of combustibles or hazardcus materials does not occur and that appropriate centrol of ignition sources is maintained, will be provided by approved administrative documents.
The autcmatic fire prctection systems represent the current state-of-the-art in providing detection of fires in their incipient stages and, in the case of extinguishing systems, also provide suppressicn functicns to control or extinguish fires before the fires can reach a size which would affect station safety.
Fire r cords show that these systems, in con unction with an effective fire prctection equipment maintenance program, have a high degree of reliability.

Mr. Harold Denton, Director December 1, 1978 Re:
Wm.
H. Zimmer Nuclear Power Station -
Page 42 Unit 1 - Appeal From Staff Fire Brigade Manpower Requirement Station (FSAR Section 17.2) assures that the fire protection system will be properly maintained throughout the service life of the station.
Primary dependence is placed upon these systems to achieve fire control in the early stages of a fire so that fire brigade response is supplementary, rather than primary, in these areas of the station.
Other areas of the station which do not contain a significant quantity of combustibles or do not contain safety related equipment are protected by manually operated fire protection equipment.
The nature of these areas is such that a fire potential does not require more than a four man fire brigade.
Fire brigades will be established consisting of appropriately trained station personnel from each major work group.
This training will be an integral part of the overall station training program, and will include classroom instruction fighting equip-jf4andpracticeintheactualuseofstationfire Periodic fire drills and retraining presentations will ment.
be conducted to ensure that a high level of expertise is main-tained in the fire brigades.
Assignment of personnel to fire brigades will consider the need for total shift coverage.
During the normal working day (day shift) when the majority of activities are scheduled which have the potential for causing fire hazards, a minimum of three (3) four man fire-fighting teams will be available.
The fire brigade team leaders during the day chift period will be appropriately trained first line supervisors such as maintenance foreman, I&C foreman, Rad-Chem foreman, or extra shift supervisors.
A total of twenty-five to thirty station employees will be trained to serve as fire brigade members.
Additionally, selected security guards will receive fire brigade training, bringing the total complement of qualified fire brigade personnel to about forty-five.
During back shift operations, a four (4) man fire brigade team will consist of two (2) security guards, cne (1) plant operator and the shift Rad-Chem technician, or two (2) security guards and two (2) plant operators.
A plant operator will be the brigade team leader during these pericds.

Zimmer Nuclear Power Station -
Page d3 Unit 1 - Appeal From Staff Fire Brigade Manpower Requirement Details pertaining to organizations, procedures, training, etc., are provided in Section 10.0 of the Fire Protection Evaluation Report.
In the event that manual fire suppression is necessary, it is generally recogni:ed that two persons in protective equip-ment are adequate to capably operate a one and one-half inch fire hose.
This would permit the two additional fire brigace members to assist hose operators with related activities such as securing spare breathing apparatus and related equipment, communication / coordination, control of local ventilaticn systems, etc.
In addition, these men would be available to relieve the initial hose operators should that become necessary.
In contrast to an industrial plant or residential areas, a power generating station has a Central Control Room which is continuously manned, and features a high level of monitoring and surveillance of fire protection circuits.
For example, the fire detectors which are-arranged in channels and
()are powered from separate Class IE bases, provide overlapping monitoring of areas which can potentially contain combustible material.
Continuous monitoring of these circuits takes place in the Central Control Room.
Additionally, fire protection valves are electrically supervised in the Central Control Room, including status display, or if not, the valves are locked in the open position.
This centralized monitoring and control minimizes response time to fire detection.
Also there are dual and diverse sources of pumped water to the fire protection lines, i.e.,
a motor-driven fire pump, and a diesel-driven fire pump.
Both are monitored in the Central Control Room.
Extensive communications available in the Central Control Room enable the fire brigade to be promptly coordinated and dispatched to areas where needed.
Features include alarms to all areas, party line circuits to aid in the response to the alarm and diverse and redundant means of communicating.
These include fixed-location telephones (dual system) and actile radios.
In conclusion, we would like to point out that some municipal fire departments respond with only three members.
Fires in the Zimmer Plant should be much smaller than most fires that municipal fire departments are called upon to fight.
Fires in the Zimmer Plant will also be detected very quickly and can be responded to promptly by a brigade which is already on site and v-

Zimmer Nuclear Pcwer Station -
Page
=4 Unit 1 - Appeal From Staff Fire Brigade Manpower Requirement knowledgeable of the plant layout.
Our fire protection program has been developed to minimite fire hazards, detect fires in the incipient stage, and promptly extinguish fires that may start.
Fire barriers separate areas to contain potential fires.
In certain plant areas, automatic systems are actuated to extinguish fires that are detected.
In other areas, reliance is placed upon the use of manually actuated systems.
Therefore, due to plant design, extensive fire detection and suppression equipment, extensive personnel training, fast response time of the brigade, a fire brigade of no more than four people is sufficient to control a fire emergency at the Zimmer Plant.
