Subject:

Zion Nuclear Power Station Fire Protection Report, Amendment 11

Reference:

Exelon Generation Company, LLC letter, "Zion Nuclear Power Station Fire Protection Report, Amendment 10," dated July 31, 2007 In accordance with the requirements of 10 CFR 50.71, "Maintenance of records, making of reports," paragraph (e), Exelon Generation Company, LLC (EGC) is submitting Amendment 11 to the Fire Protection Report (FPR) for the Zion Nuclear Power Station (ZNPS), Units 1 and 2.

In accordance with 10 CFR 50 .71(e)(4), the FPR amendment is being submitted within 24 months of the previous ZNPS FPR amendment which was submitted in the referenced letter .

The ZNPS FPR is a document incorporated by reference in the ZNPS Defueled Safety Analysis Report . Accordingly, this amendment is due to be submitted by July 31, 2009.

A summary of the changes made to the ZNPS FPR is provided in Attachment 1 . These changes reflect the changes that were made through June 1, 2009, under the provisions of 10 CFR 50.48 "Fire protection," paragraph (f).

Attachment 2 provides the replacement pages for Amendment 11 of the ZNPS FPR as required by 10 CFR 50 .71 (e) and is accompanied by a list of effective pages and instructions for updating the ZNPS FPR. We have evaluated the FPR changes in accordance with 10 CFR 50 .48(f) and concluded the changes do not reduce the effectiveness of fire protection for the facilities, systems and equipment which result in a radiological hazard, taking into account the current decommissioning plant conditions and activities of ZNPS, and do not require prior NRC approval.

This submittal accurately presents changes made since the previous submittal and reflects information and analysis performed under the provisions of 10 CFR 50.48 but not previously submitted to the NRC.

There are no commitments in this letter.

Amendment 11, July 2009 ZION STATION FIRE PROTECTION REPORT Combustible Material and Fire Loading The combustible material in this fire area consisted of cable insulation in trays and cabinets, nuclear instrumentation cable, flexible connectors (HVAC), HEPA and pre-filters, wood, charcoal filters, plastic battery casings. With a floor area of 12,266 ft2 and a total heat content of 1 .257 x 108 Btu, the average fire loading in this area is about 10,251 Btu/ft2 with an equivalent fire severity of 8 minutes. The administrative transient combustible load limit for this fire zone is 8,525 Btu/ft2.

Fire Protection Criteria and Measures This fire zone has no general area automatic fire suppression or detection .

Manual fire suppression equipment including portable fire extinguishers and hose stations are available at containment entry for fire responder use. Access routes to this fire zone are available for responding fire response personnel .

Design-Basis Fire The design-basis fire would result if the combustible materials in this zone burned . This fire could spread to other zones in the containment, since the zone boundaries are not designated as fire barriers, but it would not spread out of the containment building.

The design-basis fire is unlikely, since this zone has a low fire loading, and the combustibles present are not evenly distributed, making the likelihood of a fire spreading rather small .

Any fire likely to start in this zone would remain confined to a small area, and would not cause any major damage .

Amendment 11, July 2009 ZION STATION FIRE PROTECTION REPORT Radiological Hazard Potential A fire in this area would not create a radioloqical hazard for the following reasons :

This area contains no radioloqical material or contamination . This area is separated from radioloqical areas by fire barriers.

Equipment Important to the Defueled Condition (ITDC)

The following equipment in this area is important to the defueled condition :

None.

Although not required, the following major equipment is also contained in this fire zone:

Computer Power Unit 1 Computer Unit 1 Computer Supply Inverter: Room AC Unit: Room AC Unit:

1 CM006 0OV058 0OV059 Computer Power Supply : 1 CM010 Combustible Material and Fire Loading The combustible material in this fire zone consists of 4-inch rubber cove base, cable insulation in trays and cabinets, insulation (HVAC), M.B. blanket material, air conditioning unit internal duct lining, paper products, plastic battery casings . With a floor area of 770 ft2 and a total heat content of 7,549 x 107 Btu, the average fire loading in this zone is 98,036 Btu/ft2 with an equivalent fire severity of 74 minutes .

The administrative transient combustible load limit for this fire zone is 11,766 Btu/ft2 (equivalent to 1000 Ibs of paper).

Fire Protection Criteria and Measures This fire zone contains no automatic suppression systems, but fire detection is provided by ionization smoke detectors that alarm in the control room.

Manual fire suppression equipment in the form of a portable fire extinguisher is available in this fire zone and a hose station is available in adjacent fire areas/zones .

Access routes are available to fire response members responding to a fire in this zone. Communication equipment/smoke removal capability are available in this zone as described in the pre4ire plan.

Design Basis Fire The design basis fire would result if all of the combustibles in this room would be destroyed . This would result in loss of ventilation for the station battery rooms, and loss of 50% of the ventilation supply air to the auxiliary electric equipment room. None of these losses would adversely affect the ability to cool the spent fuel pool or result in a radiation release . The results of the design basis fire are thus acceptable.

A fire in this room would be quickly detected by the ionization detectors . Even a short duration fire may generate enough combustion products to damage the plant computer, but since it is not safety-related, this loss is acceptable from the standpoint of plant safety. The most likely results of a fire in this room are not serious .

Amendment 11, July 2009 ZION STATION FIRE PROTECTION REPORT Equipment Important to the Defueled Condition (ITDC)

The followinq equipment in this area is important to the defueled condition :

None.

Although not required, the following major equipment is also contained in this fire zone:

With a floor area of 770 ft2 and a total heat content of 5,985 x 10' Btu, the average fire loading in this zone is 77,727 Btu/ft2 with an equivalent fire severity of 58 minutes .

The administrative transient combustible load limit for this fire zone is 11,766 Btu/ft2 (equivalent to 1000 Ibs of paper) .

Fire Protection Criteria and Measures This fire zone contains no automatic suppression systems, but fire detection is provided by seven ionization smoke detectors that alarm in the control room. Manual fire suppression equipment in the form of a portable fire extinguisher is available in this fire zone and a hose station is available in adjacent fire areas/zones .

Access routes are available to fire response members responding to a fire in this zone. Communication equipment/smoke removal capability are available in this zone as described in the pre-fire plan.

Design Basis Fire The design basis fire would result if all of the combustibles in this room burned . The plant computer, which is not ITDC, would be destroyed . The portion of the computer and miscellaneous room's HVAC system in this room would be destroyed . This would result in loss of ventilation for the station battery rooms, and loss of 50% of the ventilation supply air to the auxiliary electric equipment room. None of these losses would affect the ability to cool the SFP or result in a radiological hazard . The results of the design basis fire are thus acceptable . A fire in this room would be quickly detected by the ionization detectors . Even a short duration fire may generate enough combustion products to damage the plant computer, but since it is not ITDC, this loss is acceptable from the standpoint of plant safety.

Amendment 11, July 2009 ZION STATION FIRE PROTECTION REPORT Combustible Material and Fire Loading The combustible material in this fire zone consists of cable insulation in trays and cabinets, duct insulation (HVAC), M.B. blanket material, HVAC duct lining, pre-filter modules, and paper products.
