.chment to GQL 0276 oruar7 17> 19I5 The
owing information is provided in order to:
1.
.lete our response to the NRC's Fire Protection Syste7 ew " Request for Additional Information", Question 6, 2.
Jde a partial response to the NRC's Fire Protection Systes tew Position 26, and 3.
.eisfy TMI-2 Operation License Condition 2.C.(3)l.2.
As indicated previously, the diesel generators are the only ';afety related components which are presently protected by a sprinkler system.
Inadvertent operation of the sprinkler heads located above each Diesel Generator could spray water on the equip =ent and incapacitate the generator, however, this will not preclude achievement of a safe shutdown.
9' 119 L0 1 I -
In addition, as required by the NRC's Fire Protection System review Position 8 and the TMI-2 Operatir.g License Condition 2.C.(3) 1.1, an automatic water suppression system is being designed for each diesel generator roc:. basement to pea ec.: cables.
Inadvertent or intentional operation of this new system will not adversely affect safe shutdown equipment.
An analysis has been performed postulating a rupture of the fire service piping.
The results are as follows:
1.
All fire service piping in Nuclear Safet) Related Areas ice supported to Seismic I criteria.
2.
Pipe whio need not be postulated due to low temperature (less than 200 F) and low pressure (less than 275 pcig) in the3e line s (per Branch Technical Position APCSB 3-1, Appendix, Page 3 6.1-13).
3.
Per Standard Review Plan 3.4.2, Page 3.5.2-7, for a non-liashing liquid service, as is the fire water service, no diffusion angle is allowed in the water discharge. The water will remain in a thin stream, approxiaately 6 inches wide by 3/16 of an inch deep.
The maximum potential range of this stream, under ideal discharge conditions, is 15 feet along the floor in a horizontal alstance from and perpendicular to the centerline of the piping.
Equipment within this range has been examined and it has been determined that the nature of the stream emitted from a through wali leakage crack is such that it will not affect both divisions of redundant safe shutdown equipment. Therefore, no additional water spray protection is required to protect against pipe rupture.
g Water spray protection measures that may have to be taken to protect redundant divisions of safe shutdown equipment due to the applicatien of manual firewater can only be determined af ter co=pletion of the fire hazards re-analysis which will determine what equipment is required for safe shutdown in the event of a fire in various areas.
That analysis is scheduled to be completed by May '. 1978, and, as indicated in our response to NRC Position 26, we expect to be able to propose any hose spray protection measures required at that time.
