SUBJECT:

Peach Bottom Atomic Power Station Fire Protection Modifications Progress Report

REFERENCES:

(1) Letter from J. W. Gallagher to i D. G. Eisenhut, dated February 25, 1983

! (2) Letter from V. S. Boyer to D. G. Eisenhut dated December 2, 1983

Dear Mr. Eisenhut:

l Philadelphia Electric Company, in the reference (1) letter, proposed to submit Peach Bottom's Fire Protection Modifications Progress Report every four months, starting in May, 1983. In the reference (2) letter, the Licensee discussed the

final penetration seal test reports received from Factory Mutual L

Research.

This letter includes: (I) the Fourth Modifications Progress Report issued to you (Attachment 1); (II) a copy of each final Penetration Seal Test Report forwarded to us by Factory Mutual Research (Attachment 2); (III) an update on the penetration sealing program; (IV) a schedule exemption request for certain dampers in our HVAC damper upgrade program; (V)- a schedule commitment for alternative shutdown; and (VI) a discussion of our safe shutdown instrumentation program.

~

A comparison of the attached Modification Status Report and the previous Modification-Status Report, dated January.16i, 1984, reveals that. twelve (12) estimated commitment dates of March 15,-1984, as established in the reference (2) letter,

- have been changed. Six (6) were changed to "2-EOO" and six (6) were changed to "next system. outage of sufficient duration". These changes were forced by outage. requirements or design delays for cable encapsulation and rerouting work (as. indicated in the previous' Modification Status Report, dated January 16, 1984.) Most of the completion.date slippage involves only short lengths of conduit leading to and including terminal boxes.

-bypassing the Control Room and Cable Spreading Room.

These rooms were previously separate fire areas. We have now combined these fire areas into one area with different zone identifications. Therefore, since we have redefined these fire areas as being common, we do not plan to upgrade the control room floor penetration seals based on the following:

1. The Cable Spreading Room is' protected by area smoke

. detection and an automatic carbon dioxide system.

2. The Control Room is continuously manned. Although approximately 335' existing seals have material of thicknesses which have not been tested to qualify.

! for a 3-hour fire rating, all these seals provide a

! gas-tight seal. :In addition, in many of these

! cases, some minimum depth of grout is included.

!- The limited fire resistance'of the existing floor l'

penetration seals will allow time for operator action.

3. Safe Shutdown would be accomplished from the same L alternative shutdown panels, whether a fire caused i evacuation of the Control Room or cable damage in the Cable Spreading Room.

4. Removal of existing material, such as grout from.

inside conduit, could jeopardize the integrity of ,

! the cable. (Most of the material removed on Unit 3 was polyurethane foam which was not as severe a removal problem as grout).

B. No. 3 Unit, Seal Upgrade Schedule On June 1, 1984, we expect approximately 3492 of 3545 penetration seals to be completed. The projected 53 incomplete seals are located in 31 barriers in 23 different rcams and have the following restraints:

1. Penetrations containing 4kv and 13kv cable i  ;'

-The voltage is sufficiently high to prevent a safe

work environment while the unit is operating. The 4

cable in the unsealed penetrations cannot be de-

energized while the unit is operating.

t l 2. Penetrations contain circuitry associated with

! safety-related equipment which if disturbed could

- interrupt plant operation. The equipment  ;

associated with the circuitry in these penetrations i cannot be taken out of service without affecting i

plant operation.

3. Penetrations located in areas of extremely high radiation The upgrading of penetrations :Ln these areas while i .the unit is operating would crette a significant l ALARA concern for the individuals involved.

l Therefore, station. Health Physics personnel have prohibited work in these areas until the unit is.

not operating.

4. Penetrations associated with fire dampers as described in Section IV of this letter. The k

~ Mr. Darrell'G. Eisenhut Ma'y 16, 1984 Page 4 annular regions external to the HVAC ducts in question will be. sealed after the installation of the fire dampers.

The above uncompleted penetrations will be upgraded as soon as safe access to the penetrations is possible, j These penetrations will be sealed during outages of 1 sufficient duration to encompass the access, blocking

, and installation requirements. As fire dampers are j installed, the associated penetration seals will also be

. completed.

i IV. HVAC, Damper _ Program - III.M The procurement and installation program to install 3-hour.

'. qualified. dampers in ventilation ducts penetrating safe 1 shutdown fire barriers is continuing. 'As a result of

! resurveys of. existing ductwork and dampers the number of i dampers to be installed is now approximately 90; 24 in No.12 L Unit, 22 in No.'3 Unit, and 44 in. common systems. Sixty-l five have been purchased. Damper installation has been very

{ difficult. Several reasons for the damper installation difficulties are:

1. Unforeseen problems with contamination of ductwork has

almost doubled installation time. Ductwork which

serviced very low level radiation areas has become

! slightly contaminated over the years. Work in some of l these ducts now requires not only Anti-C clothing but

!. also the use of portable HEPA filter units and i enclosures around the work area.

2. The increase in damper installation time has

, necessitated reevaluation of. critical equipment HVAC

. outages'to verify that sufficient cooling is provided to assure continued equipment operation / availability. In some cases, portable ventilation equipment is necessary, f

7 Mr. Darrell G. Eisenhut May 16, 1984 Page 5

3. Similarly, our evaluations have revealed that outages are required for several areas because we can not assure critical equipment availability during operation without ventilation to that equipment. Two unit outages are necessary in some common areas.

We expect 5 dampers to be installed by the end of this month and are proceeding as quickly as station operating conditions allow. We expect increased productivity as installers become more familiar with the specific damper installation practices required.

Therefore, we hereby request, pursuant to the requirements of 10CFR50.12 an exemption from our previously transmitted completion schedule of June 1, 1984. Our proposed schedule would be to complete No. 3 unit damper installations by September 15, 1984. No. 2 Unit and Common damper installations will be complete by the end of the ongoing No. 2 unit refueling outage.

Those Unit 3 and common dampers requiring an outage will be completed during outages of sufficient duration to allow access, blocking and installation.

V. Alternative Shutdown - III.L A number of alternative shutdown modifications have been defined for each unit as well as for common plant systems.

These modifications have not yet been itemized on the attached PBAPS Fire Protection Modification Progress Report because PECo is still awaiting the issuance by the NRC of a revised Safety Evaluation Report on the September, 1983, submittal. Unit 3 alternative shutdown modifications are scheduled to be completed by the end of the 1985 Unit 3 refueling outage. Unit 2 alternative shutdown modifications are scheduled to be completed by the end of 1986 Unit 2 refueling outage. The common plant systems (Diesel Generator Controls and Emergency Service Water System controls) will be completed on the 1986 Unit 2 refueling outage. Consequently, alternative shutdown capability will not be available on either unit until the conclusion of the 1986 Unit 2 refueling outage.

VI. Safe Shutdown - III.G The June 1982 submittal provided design criteria to protect instrumentation cables for the process parameters. When the

e- 1 l

. . l Mr. Darrell G. Eisenhut May 16, 1984 Page 6 decision was made to install an alternative shutdown system, the work on the instrumentation rerouting was deferred due to different readout locations required for alternative shutdown. The work has now been re-initiated to provide sufficient information at both the alternative control

' stations and in the Main Control Room to safely shutdown the plant. We are presently planning to. include the applicable process parameters as defined in Attachment 1 to Information Notice 84-09. For Peach Bottom, these process parameters are:

a) Reactor water level b) Reactor pressure c) Suppression pool water level d) Suppression pool temperature e) Containment pressure f) Condensate storate tank water level g) In addition, diagnostic instrumentation (i.e., pressure or flow) will indicate the status of the following systems in the control room:

1) Reactor' Core Isolation Coolant (RCIC)

2) High Pressure Coolant Injection (HPIC)

3) Core Spray (CS )

4) Residual Heat Removal (;RHR)

5) High Pressure Service Water (HPSW)

6) Emergency Service Water (ESW)

Diagnostic instrumentation will indicate the status of the HPCI, RHR, HPSW, and ESW at the alternative control facility. The diagnostic instrumentation will be available at the appropriate local control panel location whenever its respective system is required for safe shutdown.

The identification of system and process parameter cables and the location of those cables has been completed. To protect cables associated with the instrumentation necessary for safe shutdown, rerouting and/or encapsulation of a portion of these cables will be necessary. Modifications (MODS 1029E, 1352B&H, 1353B&H) have been initiated to identify exactly which cables will be rerouted or encapsulated and modify them as necessary. Status of rerouting and/or encapsulation of these cables will be provided in the next submittal of the Peach Bottom Fire Protection Modification Progress Report planned to be submitted by September 17, 1984.
