Dear Mr. Thompson:

Philadelphia Electric Company, in the Reference (1) letter, proposed to submit Peach Bottom's Fire Protection Modifications Progress Report to the NRC every four months starting in May, 1983.

This letter includes: (I) the seventh Modifications Progress Report (Attachment 1); (II) an update of the penetration sealing program; (III) an. update of the fire damper program including an exemption request; and (IV) a progress report addressing structural steel fire protection.

-Modification Progress Report The attached modification l status report indicates that one modification has been completed since the last previous report dated January, 1985.

All other modifications, with the exception of two modifications discussed in detail

[

below, are progressing on-schedule.

(1)

Completion of the installation of the cross-tie feeds for the battery chargers will be delayed due to problems with equipment delivery.

The installation

~

will now be scheduled for a non-outage period subsequent to equipment delivery.

(2),

The lack of availability of qualified thermal-magnetic type breakers necessary to replace several of the 480 Volt motor control center magnetic-only circuit breakers continues to delay completion of the breaker replacement modification.

We are expediting qualification and delivery of these breakers.

7 II.

Penetration Seal Program III.M 4

A.

A total of 6246 penetrations through 342 fire barriers i.

which required sealing were ideatified.

Approximately 51 of these penetrations still require sealing.

Seal completion activities are being performed by Philadelphia Electric Company Construction personnel.

B.

-A fire test was-performed April 16, 1985, during which a new seal system and a procedure for pulling cable through existing seals successfully passed the ASTM E-814 fire test.

A seal system using Nelson Flameseal Fire Stop Putty and ceramic fiber passed the test and will be used in small conduit.

Additionally, a procedure to pull cables through existing silicone foam penetration seals without extensive seal material removal and rework was qualified.

C.

Another test is scheduled for early June to demonstrate the ability of polyurethane foam and ceramic fiber to withstand the hose stream test following a fire test duration of 1-1/2 hours to enable the use of this type fire seal.where the combustible loadings on each side of the barrier are

'less than one hour.

The use of this seal was explained in detail in the letter indicated as

III. HVAC Damper Program III.G.2 A.

Installation The-installation of three-hour quali21ed dampers in ventilation ducts penetrating safe shutdown barriers is continuing.- - The most recent status was transmitted by-letter to the NRC (Reference 4) which reported that the damper installationLaodifications are approximately 65% complete.

B.

Damper Exemptions-Radiological safety concerns have been_ identified in two areas where we request exemption from-the requirements of 10 CFR.50, Appendix R, Section III.G.2, which requires the separation of cables, equipment and associated non-safety circuits of redundant; trains by a fire barrier having a three-hour rating.

The safety concerns involve the installation of fire. dampers in ducts which penetrate fire barriers as described:below:

1.

'Radwaste Building Equipment Cell Exhaust-Fans OAV,

~

OBV-41 The Equipment Cell Exhaust System duct penetrates the west wall of the Radwaste Building Fan Room, Elevation 150.

This exhaust system vents the Condensate Phase

_ Separator Tanks and the Waste Surge Tanks, and other radwaste processing equipment inside the Radwaste Building.

The fans pull air from potentially contaminated areas and. exhausts the air through high efficiency filters.

The operating staff has determined that taking this ventilation system out-of-service while installing a fire damper might permit

-contaminated gas and particulates to migrate to non-contaminated areas within the Radwaste Building, creating an unacceptable jeopardy to plant personnel.

2.

'Radwaste Building Exhaust Fans OAV, OBV-42 The exhaust duct associated with the Radwaste Building Exhaust Fans penetrates the same barrier as the Radwaste Building Equipment Cell Exhaust duct.

Both of these ducts tie into a common discharge duct at a

E l-Mr.L Hugh L. Thomp :on, Jri May 23, 1985 Page 4

)

location'less than 10. feet from the barrier.

The l

operating staff has determined that; due to the i

ducting arrangement, the. work involved in the installation of a fire damper in this duct would.

expose workers to an unacceptable radiation hazard and would, at the same time, provide a-path to clean radiological areas for the exhaust of the Equipment Cell Exhaust fans.

A schematic of the ducting is attached-(Attachment 2).

The locations Where we are requesting an exemption from the rule are described as follows:

The barrier at the locations described above separates I

There are l

cable trays located in this duct chase; however, the thirty-minute fire resistance reflected in the table

[J above is due in most part'to cable-trays-located at the ceiling of the. fan room at Elevation 165.

Because of the spatial separation of these fixed combustibles from the barrier penetration locations, the chance of propagation of a fire through~the barrier is l

l negligible.

Based on the minimal combustible loading at the barrier location and radiological plant. safety concerns, we request an exemption in accordance with Section 50.12 of the Commission's regulations from

. Appendix R,-Section III.G.2 for these two fire dampers.

IV.

. Structural Steel Fireproofing III.G.2 t

The structural steel survivability analysis was submitted via letter to the NRC on March 29, 1985 (Reference 3).

The analysis indicated twenty-seven plant areas Which had total area fire durations and temperature problems which exceeded

r-

' 'Mr. Hugh L. Thompson, Jr.

May 23,.1985 Page 5 i

structural steel survivability acceptance criteria.

Sixteen additional plant areas-were identified which did not have totalfarea temperature problems but exhibited localized heating problems due to the location of cable trays in proximity.to exposed steel.

Sixty localized problems have been identified in these sixteen plant areas.

We are presently evaluating several alternative' methods which would protect exposed steel, including fire protective coatings, installation of sprinkler systems, and the

-possible use of solid _ tray covers to alleviate flame impingement on steel beams.

Philadelphia Electric Company will provide a tentative list of-proposed corrective actions-to the NRC_to alleviate the fire related problems in all jeopardized plant areas by June 1,

1985.

If you have any questions regarding this matter, please do not hesitate to contact us.

Very truly yours, DOB:vdw Attachments cc:
