TESTIMONY 0F BRIAN R. McCAFFREY FOn THE LONG 16 LAND LIGn11NG COMPANY ON SDFFOLh COUt41Y CONTENTION 17 -- FIRE PROTECTION Purpose This testimony establishes that LILCO nas ocalt adequately witn che risk of toxic gas in the Shoreham control room, ano that there is no neea to install manual pull boxes in ene Shoreham machine shop.
LILCO has minimized the potential for toxic gas (1) by j
installing most control room cables in a room separate from the control room, (2) by using fire-resistent cables to minimize the possibility of fire, and (3) by installing fire-oetection and tire-extinguishment systems in the cable-spreading ano con-trol rooms.
LILCC will also install a toxic gas cetector in the Shoreham controi room as anotner line of cerense against fire hazards.
the machine shop, located adjacent to tne control room, i
has an automatic fire-dctection system ano an automatic sprink-1er system.
Three Gai-tronic pnones are installeo in the machtne shop; these phones can be useo to report a fire when ene macnine shop is occupieo.
rianual pull boxes are unnecessary.

I 1.
G.
Please state your name anc business aoaress.
A.
My name is Brian h.
McCatftey; my business acotess is Long Islana Lignting Company, 175 East Clo Country Road, Hicksville, New York.
2.
C.
'.ih a t is your position with L1LCO?
A.
I am 11egulatory Superviscr for LILCL, responsible ror managing tne Nuclear Regulation Division or tne.
Nuclear Operations Support Lepart.nent.
In adoition, I am responsible Ior managin3 ano cooroinating tne Company's efrorts in the A6LB licensing proceeolngs.
2.
G.
Please state your protessionci qualificatione.
A.
Ine attacheu resume summarizes my professional quall-fications.
hy familiarity with tne tire protection l
. _,_.. _. _,.. _ ~ _,
. issue stems from my involvement in botn licensing ano engineering matters concerning tne shoreham planc.
Immeciately preceuing my current assignment, I was Managet of Project Engineering tor che snorenam Station; as such I was responsible tor engineering ano licensing of Shocaham.
I have been involvea in tne Shoreham project for nine years.
4.
G.
Are you tamiliar with Suffolk County Contention 17t A.
Yes.
5.
C.
What issues are presentea in tnat contention?
A.
The County wants LILCG to install a toxic gas cetec-ticn anc warning system in the control room and manual fire alarm boxes in the machine snop area at elevation fifteen feet.
6.
C.
Iaking the issue of a toxic gas detector rirst, what woulo cause toxic gas in the control room?
J A.
Tne primary potential source of toxic gas in tile con-trol room is burning cables in the event or a tire in that area.
If toxic gas enters the control room, operators maj be affectec, impecing tuelt acility to operate the plant from the control room.
7.
C.
What steps nas LILCG taken to prevent toxic gas from entering the control room?
A.
LILCU has ilmiteu the potential tor toxic gas in three ways.
(1) by minimizing cables in the control room, (2) cy using cire-resistent materials, anu (3) by installing f i r e-oe tec tion equip.nen t.
. 8.
G.
As to the first methoo you mentioned, how has L1LCO limite6 cables in the control room?
A.
Cables are locateo in the cobie spreacing/ relay room directly uncerneath the control room; tne control room itself has no exposed cables.
Cables enter the con-trol room through tloor penetrations ano come up i
directly into the control room panels.
'the ricor een-etrations are sealed.
Should a fire occur in ene cable-spreaoing room, any toxic gas that might rorm would not seep into the control room oue to these pen-etration seals.
9.
G.
hhat fire-resistant materials are usec at Shorenam?
A.
The 300 V and bu0 V control ano instrument cable insu-lation is mace or non-corrosive, clame-rctaroant crosslinked polyethlene, with a flame-retardant neoprene overall jacket.
The coaxial ano triaxial cable insulation is made of polygnerylene or polyolefin, with an overall jacket or polyolerin.
A11 cables cor 6horeham are tire retardant ano testeo in accordance with applicable IEEE ano AdTh stunodrcs.
In acoition, ventilation duct insulation is mouc of a fire-retaroant riberglass, in compliance witn I;FEa 90A, incluaing such components as the adhesive and tapes.
Tnese rice-retardant materiais ailnimize the possibilities of tires at Snorenam.
. 1 j
10.
C.
As to the thiro method you mentioneu, what fire-detection systems have been installeo in tne control room?
A.
all control room panels have ionization detectors tnat i
alarm on the security panel ano alert the operators to s
a developing fire within a cabinet betore there is any extensive damage or release of toxic vapors.
There are also ionization smoke detectors mounteo in tne control room ventilaticn recirculation air ouct work i-as well as on the intake auc t work.
They will alarm on the security panel, providing the operators witn an
)
l early warning signal or any tire in the control rooni that might not be physically observeo at an early stage.
11.
O.
What fire-oetection methoos have been installed in the cable spreading room?
A.
The cable spreading room is equipped witi: an early 1
wsrning ionization staoke uetection syscem that w111 alert the plant operators during tne early stoyes or a j
fire.
ihis room's inventory of materials is limited to cabling and cabinets.
Plant proceuures pronibit the storage or any combustible materials in tnis room, l
precluding tires involving transient ma te r ials.
The room also nas a heat-actuateo autometic total-flooding CO system that will isolate the room by 2
t a
5
-s-closini all doors anc shutting co.n the ventilation system, thereby allowing the CC, to extinguish any fires at an early stage, ano preventing toxic gas from forming.
i I must say that given the Integrity of the floor seats due to the separation of the control and cable spreao-ing rooms, the flanie-retardant cabling, tne ionization smoke and heet detectors, ano the automatic total-flooding Co. system, it is unlikely endt toxic fumes would enter the control room to make it uninnabitable.
12.
C.
In the event that the control room became uninnabit-able cue to toxic fumes, how would operators continue to run the plant?
A.
In the unlikely event that control room operators were forcao to leave the control room, Shorena.a also has installeo a remote shutdown panel as requireu by GLC 15, located in the reactor builoing seconoary contain-ment, from which sufficient controis and instru-mentation exist to snut the plant cown safely.
13.
C.
Given tne safety features you have outlinea above, does L1LCO have any plans to Install a toxic gas detector in the control room?
A.
To provide an additional safeguarG against fire hazards, LILCG is proceecing to evaluate ano purchase l
a portable toxic gas detector for the Shorenam control room.
'Inis unit will be locateo in the control room
e
! i i
I ana have the capacity to sense CO ano other hazarcous 2
products of combustion, including those trom cable insulation, ano alert operators to their presence.
i 14.
Q.
Let's turn to the second part or the tire protection e
i i
issue -- manual fire boxea in the machine shop.
t Where is the machine shop at elevation 15 f eet loca-teo?
1 A.
Tne machine shop is an area adjacent to the controi bullaing, used ror repair operations.
j 15.
C.
Are any flammable materials stored thera?
A.
Present plans for this machine chop oo not call for any permanent storage of large quantities of flammable, toxic or hazardous materials.
Some small quantitiea may be located in the arca for use in on-1 going work activities, but these quantities are lim-ited by Station Procedures.
The Cil Storage Room,' Welding Shop, Electrical Repair Snog ana Tool Room adjoin tne machine shop.
ine gen-eral storage areas north of the machine snog house any i
large quantities or llammable materials.
These mate-rials are storea in a UL-approveo storage cabinet in the north end of the warehouse area -- away trom the control room.
See the drawing at page 9 or my testi-mony.
16.
G.
Is there an automatic fire extinguishment system in i
l the machine shop?
i 1
A.
Yes.
The warehouse, machine snop, oil storage room anc weloing areas are protecteo by automatic s rinKler e
systems.
Actuation ot any sprinkler will alarm in ene main control room ano indicate the location of the fire.
During normal worn hours, the machine shop is occupied and fires would be reported to the control room via one of the three Gai-Tronic phones located in the machine shop, as shown on the crawing at page 10 of my testimony.
The control room personnel would then sound the station alarm.
There are also portable CO extinguishing units strategically placea througn-2 out the machine snop area.
17.
Q.
Would a fire in the machine shop pose any safecy threat to the control room or any satety-related areas?
A.
Even if there were a sustained fire in the macnine snop, there would be no etfect on cafety.
The raacnine shop area is separated from both the control bulloing and turbine building by 3-hour rated tire walls.
All doors through these walls are also ratec 3-nour anc have the required UL stamp.
Inererore, there is ace-quate protection of sarety-related equiement enrough l
the use of barriers, procedures, phones ano automatic spctnklers.
The use of ionization cetectors in the control room air supply would indicate any smoke con-dition trom the outside ano the operator coulo reaolly l
~
- l
_g-switch to the alternate intaxe on ene east sloe or the plcnc if necessary.
18.
C.
Why hasn't LILCO installeo manual pull boxes in ene machine shop?
A.
Eecause man'ual boxes are unnecessary.
An automatic 4
l fire detection and sprinkler system has been provioed i
anu there are three Gal-cronic_ phones available in the macnine snop for use in reporting fires if tne machine shop is occupied.
i 19.
Q.
Kould manual pull boxes afforo any better chance or notirication of a fire than the phone system't A.
None at all.
If a fire is cetecteo by personnel in l
the machine shop area, the Gai-tronics phone system is as ettective as a pull box.
The aovantage of a pnone is to provide more descriptive inrormation on the i
l nature or the fire to the station fire brigace.
20.
C.
Please summarize your testimony.
A.
Through the use of tire retaroant materials, tire detection and extinguishment systems, penetration seals and the commitment tor a portable toxic gas detector, LlLCG has acequately adoressed the concern over potential toxic gases in tne control room.
In aaoition, manual pull boxes for the reporting or pos-tulateo fires in the machine shop ere not necessary to maintain sate conditions.
The sprinkle system ano tne Gai-tronics phone system provide a superior level or protection to the machine shop.
