PALO VERDE FIRE PROTECTION INSPECTION
Dear Nr. Wade:
This report summarizes the work performed under your P.O.
5919005 related to the NRC fire protect1on review and inspection of the APS Palo Verde Nuclear Power Plant, Unit l.
Two s1te vis1ts were made to Palo Verde on October 22-26, 1984 and November 14-16, 1984.
In con)unction with the site vis1ts, a var1ety of documents were reviewed for f1re protect1on related comm1tments and procedures.
This document rev1ew, which took place both on site and 1n our off1ces, included:
The f1re protect1on SER.
The fire protect1on port1ons of the FSAR.
Those port1ons of the plant Technical Spec1ficat1ons related to f1re protection systems and equipment.
Various plant procedures developed to 1mplement the Technical Spec1f1cations and other f1re protection commitments.
Documentat1on related to f1re protecti on tra1n1ng comm1 tments for fire brigade, security personnel, and general plant employees.

Mr. W. December 17, 1984 Page two Dur1ng the site vis1ts, my primary role was to prov1de techn1cal support to Mr.
Ph1111p squalls, the NRC Region V F1re Protection Inspector.
Var1ous fire protection related items were rev1ewed and discussed with NRC and APS personnel, most of which were sat1sfactor1ly resolved dur1ng the course of the 1nspection.
I partic1pated in an exit meeting held at the conclusion of each of the two s1te v1sits.
The following summarizes the sign1f1cant 1tems requiring addit1onal fol1 owup; with each 1tem I
have al so indicated my understand1ng of 1ts status as of the exit meetings.
1.
Fire Loo Modificat1on:
SER Sect1on 9.5.1.2 conta1ns a comnitment to mod1fy the f1re ma1n such that e1ther pr1mary or secondary water will be available should a single interior 11ne break occur.
At present, in one portion of the Aux111ary Bu1ld1ng, a s1ngle break could cause the loss of both pr1mary and secondary f1re suppress1on water.
Status:
APS personnel bel1eve this cossaltment was resolved on the basis that adequate protect1on can be prov1ded by lay1ng hose 11nes 1nto the affected area from ad)acent areas.
No documentat1on was ava1lable to substant1ate that this was accepted by NRR; therefore APS was to pursue and document resolution.
2.
Missle Doors as F1re Doors:
SER Section 9.5.1.3 conta1ns a coranitment to provide UL labeled fire doors; however, unlabeled m1ssle doors have been 1nstalled 1n the fire barr1ers at the entrance to the cable spreading rooms.
Status:
APS will pursue and document resolut1on to have the mlssle doors accepted by NRR as prov1d1ng adequate f1re resistance for the fire load1ngs present.
3.
Cable S readin Room F1re Su ress1on:
SER Sect1on 9.5.1.5 1nd1cates that the cable spreading room will be protected by a water spray system.
However, the protection 1nstalled 1n th1s area is a
preact1on spr1nkler system.
Status:
Conversation with the NRR rev1ewer lndlcates that a preact1on system 1s acceptable.
The SER will be revised accord1ngly on the bas1s of a letter from APS documenting the change.
4.
Fire Detector Covera e:
SER 3/l/84 Supplement conta1ns a
comnitment that fire detectorfs will be 1nstalled 1n the
"spray chemical accumulator room".
However, such a
room or equ1pment does not now ex1st.
It appears the area was misnamed and 1t is probably now provided with f1re detectors under another des1gnation.
, Status:
APS will resolve the confus1on with NRR and document.
Hr. W. December 17, 1984 Page three 5.
FlamIable Gas Stora e:
SER 3/l/84 Supplement contains a comm1tment to prov1de venti 1ati on 1n an aux111ary bu11 d1ng f1 amnabl e gas storage room in accordance with NFPA Standard No. 51.
However, the ventilation system as 1nstalled w111 not meet NFPA requ1rements.
6.
Status:
APS w1ll revise vent1lat1on system and document changes.
Preaction S stem Actuation:
FSAR Section 9.5.1.2.2.G ind1cates that preaction sprinklers are actuated by a
cross-zoned smoke detection system.
However, these sprinklers are now actuated by e1ther a
smoke detector or a line-type heat detector.
Status:
A Licensing Inqu1ry Request has been written to rev1se the FSAR.
7.
8.
Add1tional Fire Ext1n u1shers:
FSAR Section 9.5.1.2.1.1 indicates that portable f1re ext1nguishers will be prov1ded utiliz1ng NFPA guidelines.
It appears that travel distances to portable f1re extingu1shers in Fire Zones 37C and 37D are excess1ve.
Status:'PS to evaluate and prov1de add1tlonal extlngu1shers as requ1red.
General Em lo ee Train1n:
FSAR Sect1on 13.2.1.5 contains a
commitment to provide certa1n f1re protect1on-.tra1ning to station personnel.
The present tra1n1ng program will not adequately reflect the plant situation after fuel loading in the areas of f1re alarm sounds, evacuat1on plan posting, f1re report1ng, and ignition source control.
Status:
APS w111 rev1ew with 1ntent to update tra1nlng nater1als prior to fuel loading.
9.
Securit Personnel F1re Trainin:
FSAR Sect1on 13.2.1. 5 conta1ns a
commitment to provide certa1n fire protect1on train1ng for security personnel.
The present tra1ning material s and procedures do not adequately cover the handling of off-site f1re department personnel (e.g.,
no indication that phone authorizat1on 1s required pr1or to entry, and no clear 1nstruct1ons on escorting 1ndividual firemen).
Status:
APS will rev1ew and revise as necessary.

Mr. M. 0.
Made December 17, 1984 Page four 10. Main Steam Isolat1on Valves:
An open1ng at the top of the barr1er between the ma1n steam isolat1on valves would result in a fire in one valve enclosure opening spr1nkl ers over the other val ve.
The potential that such an 1nc1dent could result 1n loss of both valves due to fire and/or water damage should be evaluated.
Status:
APS w111 document their englneer1ng conclusions that the electrical system and p1p1ng on the valve not involved 1n a f1re would not be damaged by spr1nkler water d1scharge.
Thermal Shock on RCP 011 Collect1on S stem:
The tanks for the reactor coolant pump oil leak collect1on system contain s1ght glasses wh1ch could potentially break due to the thermal shock of hot oil entering the tank.
The resulting o11 sp111, 1f ign1ted, could damage systems ins1de conta1nment.
12.
Status:
APS w111 document the1r englneer1ng conclus1on that the sight glass will not break due to thermal shock, and that 1f 1t should, excess flow valves
.and floor dra1ns would limit f1re damage to acceptable levels.
Fire Effects on Main Feedwater Isolat1on Valves:
An unprotected electrical
)unct1on box 1s connected to a
f1re wrapped cable (1EZCl EARX06)
at the ma1n feedwater 1sol ati on val ve.
There 1 s concern that f1re could damage the safe shutdown electr1cal circu1ts 1nside the box.
13.
Status:
APS w111 document that the1r current safe shutdown analys1s 1nd1cates the electr1cal clrcu1ts 1nvolved do not requ1re f1re wrapping in this area.
HVAC Shaft 0 en1n:
An open1ng covered w1th plywood was observed in an HVAC shaft 1n the west end of the Auxiliary Building, elevation 120.
Status:
A f1re damper 1s to be 1nstalled 1n th1s opening; the 1tem has been punch 11sted.
14. Containment Charcoal charcoal filters 1n supply the spr1nkler Filters:
A special f1tting 1s required on the containment in order to attach a f1re hose to system 1ns1de the f1lter enclosure.
Status:
The requ1red fittings are on order and will be 1nstalled when rece1ved.

Control of Contractor Activities: During the. f1rst site v1sit, there were many examples of noncompl1ance w1 th plant f1re control procedures on the part of contractor personnel.
These included fire doors bl ocked open, wel d1ng without foilow1ng permit procedures, combust1ble wood scaf folding in safety related areas, and lack of smoking control.
status:
During the second site vis1t, a great deal of 1mprovement was noted in respect to the problems prev1ously observed.
APS 1nd1cates that the changeover from the A/E to 11censee control 1s proceeding in an orderly manner and is expected to be fully 1mplemented by fuel load1ng.
F1re Bri ade Assi nments:
Of the five required f1re br1gade personnel on sh1ft, three are assigned by the sh1ft supervisor from operat1ons, and one 1s ass1gned by the chemistry supervisor and one by the radiat1on protect1on super v1sor from their respective groups.
However, formal supervisory responsib111ty has not been establ1shed to require that at least one member of the chemistry and rad1at1on protect1on groups on duty at any given t1me meet current fire br1gade training requ1rements.
Such respons1bili t1es should be documented.
Status:
There was no spec1f1c coassitment made by APS to comply with this recomsendat1on, although oral assurances were prov1ded that at least f1ve properly tra1ned f1re brigade personnel would be ava1lable, at the site at all t1mes.
17. Contractor Enclosures:
Metal enclosures have
.been prov1ded for contractors in areas containing safe shutdown systems.
Da1ly inspecti ons should be made to be certain that there are no combust1bles stored in these enclosures wh1le they remain 1n use.
Status:
Plant procedures are to be revised to comply with this recommendation.
18.
Tech S ec Procedure Com let1on:
Many of the procedures requ1red to implement Tech Spec requirements were still undergoing rev1s1on.
Of part1cular concern were two procedures relative to the fire detect1on and signaling system:
36ST-9QK01 and 36ST-9QK02, which had extensive rev1sions in process.
Status:
APS aware of needs and expects to have procedures ready to implement when required.
