t"iAY-84-1995 15: 46 AEPSC NGD 1 614 223 2884 P.87M3 R soons~ to Question 16o: Me feel that IPPA 'p2D is an extremely poor guide to be used for nuclear power plants s'nce ~t is much too general in nature.

However, we ecog~"'ze tha.t it is, at this time, the only guidance available.

Me also note that this question has apparently expanded in scope to include waterflow and va3.ve supervision, whereas Append3.x A to B.T... APCS'3 g.y-only referr d to N.""PA '72D in 3:tern E.l.(a) for fire d.;-. ction. 3n responding to Appendix A to 3.T.P. APCSB 9.0-1 we co""area the requi."ements of.;riA '72D to the fire detection/suppressio.. system cor trol at the Cook Nuclear Plant. As stated, 'therein >re are in agreement with all the appli.able portions of HFPA p2D except for the testing frequency. R s ons to Question 6c: The detector system circuitry is described. below for the two types of fire detection in use at the Cook Nuclear Plant. (1) 0 i t n b oduct of co 0'st'I 9 i~ i ptpct on,-. The ionization detector utilizes the principle wherein air .is made electrically conductive (ionized) by exposure to a minute source of alpha radiation emitting material, Mericium 243.. The ionizing ma.erial is locatea ir. the outer or detecting chamber of the detector ;.hica is open to tne atmosphere, ar.d in an inner or compensat ng cha"ber OI the aetec-.or vaich, except for a.small vent to co=.pensate for temperature ara pressure

changes, is essentially clos d to preIent entrance 0

combustion products. The outer.~"" '. -.er c'bers a e con.".ected in pa"a with the.anode a."a ca=hode of a spec"'"-l gas d'scha ge (cold cathode) ~be. The ]unction between the outer and iiower chambers iq connected to a starter elec rode of the cold cathode tube ~' voltage is applied across the outer and, inner ionization chambers causing a minute e3,ectriea3. cu=rent flo..'. 'rthen products of comoustioh enter the exposed outer

chamber, the resistance to current flow increases and the voltage between the cold. cathode tube starter electrode and the cathode increases and, fires the tube.

The current which then passes between the anode and, cathoae of the tube is sufficient to energize a zone relay and a corresponding alarm relay in the main ionization contro3. unit. The zone re3.ay is a special 3-position relay incorporated in the detector circuit to give an alarm in case of fire and. to supervise the system against defective detector heads, broken wires, or a sim'lar failure that would make the system inopera-tive. Such a failure vill de-energize the relays and c3.ose NAY-84-1995 15:46 PSC NGD 1 614 223 2884 P.88i23 You.,state that an ionization fire protection system alarming at. the fire system contxol panel is installed below tne control room suspended. ceiling in the area behind the control panels. Appendix A to Branch Technical Position 9.5-1 requires that detectors be placed in each control room cabinet. Explain. how the operator will know the location of the fire if detectors are not placed. in each cabinet.

Response

to Question 5P:

The control room cabinets at the Cook Nuclear Plant, con-sists of open and closed cabinets., Should.

a fire occure in any of.

, the open cabinets in the c'ontro1 room,.the products of.combustion

~

.%11 readily escape and be-.sensed.

by,the early warning ionization,e detection system.

These detectors will alarm audibly and, visually at the emergency fire'panel in the Control Room.

The closed

.'cabinets in the Control Rooms.-are not. air tight and 'in most cases are louvered. to allow internally generated heatto dissipate into" the Control Room.'rodu&s. of combustiom and.

smoke from a fire--

in the cabinet vill also escape and be sensed by t¹ ionization detection system.

These detectors, operating as a zone> will alarm audibly and. visually at the.Control Room emergency fire panels On receipt oX'his alarm, due to a fire in either an

~ open or closed, cabinet, the operator must investigate

behind, he panels to observe'for the. pulsing neon lamp on each detector it-self until he finds the operating detector.

At this point he can use hand portable fire extinguishers already available in the Cont ol Room and. behind, the control,panels to attack the fire.

In this manner>

a fire in a control room cabinet vill be detected in its ea-ly stages

~Q, be ezt'sh d be ore it could. spread i~ther.

Should additional fire fighting apparatus be required, water hose standpipes, CO2 hose reels anCi. breathing apparatus are available just outside the control room entrance for operator use.

t%Y-84-1995 15:47 1 614 223 2884 P.18i23 CODE2154.DEK NFPA 72D 1967 Edition Coda Section 2154 Deviation:

Documentation was not available to confirm that the alarm initiating end signaling circuits and cables installed for the systems

reviewed, have met the criteria required by this code section for limited energy cable.

Justification:

Tha review of the Record of Conversation memos dated 6/8/88 and 6/9/88 in addition to the drawings referenced below, confirms that the alarm initiating and signaling circuits and cablas installed for the Chametron C02, Pyrotronics system 3 and FIU systems and the Rochester "EF" annunciator panels, meet the requirements of this code section with the exception of the requirement that the cables be approved for the application of a limited energy cable.

A review of the cable description telex dated 3/16/88 forwarded to Impell from AEPSC, indicates the type, size and quantity of conductors for selected cables.

The description of the type of insulation is also provided.

The cables reviewed meet or exceed the requirements of Code Section 2155 which provides the requirements cable characteristics.

Based on the review of this documentation, an equivalency can be made that tha cables

reviewed, will meet the requirements of Coda Saction 2155 due to the attributes of the construction features of these cables.

Since the circuit characteristics for the alarm system meets the requirements of Code Section 2154 and an equivalency has bean made to confirm compliance with the requirement for an "approved

" cable as verified under Coda Section 2155, these cables ara considered to be acceptable for use in the alarm system as installed,

(312) 534-3.000 Summary of Conversation I requested data on the following equipment:

a.

Maximum circuit current output from the CO system relay cabinets b.

The hydrostatic pressures and equivalent lengths for the CO2 selector valves c.

Maximum pull pressure and travel distance of ENPC cabinet manual actuator IIr. Dimetravich indicated the followingz a.

The largest power consuming component connected to the relay cabinets are the EMPC solenoids.

These devices are all 10 watt solenoids.

~ DEK HFPA 72D 1962 Edition Code Section 2223 Deviation:

Documentation reviewed indicated that the power cables connected to the Alison Control panels A924 from power panels 162-DAB, circuit 5, are under sized for the 35 AMP breakers provided.

Justification:

Based on the review of the letter from E.A. Taylor to B.J, Gerwe, indicates that these cables are adequate for the currents involved and are equivalent to the No.

10 A'VG. wire required.

Therefore, these cables are considered acceptable.

This memo is in response to your request for information dated 2/25/88.

Ve have reviewed the recommendation on Code Section 2223 dealing with the comparison of a 87/18 AVG cable vs.

a 810 AWG cable.

The recommendation was to replace the 87/18 AVG with a f10 AVG.

An engineering evaluation was performed comparing a 87/18 to a f10 cable.

A 0'7/18 AVG wire is larger than a 810 AVG and therefore the recommendation for upgrade to a 810 AVG is illogical.

The other item requiring investigation, Code Section 2154 on energy limitations, is awaiting further clarification from
