QUAD 0111l5 DPR 29 3.12/4.12 LlH111NG COND1110NS FOR OPERA 110N AND

$URVElLLANCE REQUIREMEN15 BASES The operability of the fire suppression systems insures that adequate fire suppression capability is available to confine and extinguish fires occurrin0 in any port.fon of the facility where safety *related equipment is located. The fire suppression system consists of the water system, sprinklers, 00,, and fire hose stations. The collective capability of the fire suppression syltems is adequate to minimize potential damage to safety-related equipment, and is a major element in the facility fire protection program.

Operability of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection of fires. This capability is required in order to detect and locate fires in their early stages. Prompt detection of fires will reduce the potential for damage to safety-related equipment, and is an integral element in the overall facility fire protection program. In the event that a portion of the fire detection instrumentation is inoperable, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is returned to service, in the event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the i affected areas until the affected equipment can be restored to service.

A fire suppression water system shall consist of a water source, pumps, and distribution piping with associated valves. Such valves shall include yard hydrant curb valves, and the first valve ahead of the water flow alarm device on each sprinkler or hose standpipe riser.

In the event that the fire suppression water system becomes inoperable, immediate corrective measures must be taken since this system provides the major itre suppression capability of the plant. The requirements for a 24-hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provide adequate fire suppression capability for the continued protection of the nuclear plant.

The functional integrity of the penetration fire barriers ensures that fires will be confined or adequately retarded f rom spreading to adjacent portions of the facility. This design feature minimizes the possibility of a $1ngle fire rapidly involving several areas of the f acility prior to detection and extinguishment.

The penetration fire barriers are a passive element in the facility fire protection program and are subject to periodic inspections.

' FIRE PROTECTION SYSTEMS" e

EVALUATJ_Q)] EQB BIGNIFICANT HAZARDS CONSIDERATION Proposed Deletion of Specification 3.12/4.12 Fire Protection Systems The proposed changes provided in this amendment repest are made in order to implement the recommendations of Generic Letters 88-12 and 86-10. These changes have been reviewed by Commonwealth Edison Company and we believe that they do not present a Significant Hazards Consideration. The basis for our determination is documented as follows:

BASIS EQB HQ SIGNIFICANT HAZARDS CONSIDERATION Commonwealth Edison has ovaluated this proposed amendment and determined that it involver no significant hazards consideration.

In accordance with the criteria of 10 CFR 50.92[c) a proposed amendment to an operating license involves no a:.gnificant hazards consideration if operation of the facility, in accordance with tho proposed amendment, would not:

1) Involve a significant increase in the probability or consequences of an accident previously evaluated, because:

The proposed change to ret 've the Fire Protectjor. Technical Specifications does not involve a significant increase in the probability or consequences of an accident previously evaluated because the change doc 1 not involve a physical l modification to the plant, a change to any safety system or a I

change to any setpoint. The administrative concept of concurren.ly removing the fire protection reguirements from the Technical Specifications and incorporating these elements into the UFSAR does not affect the safety analysis presented in the Quad Cities UFSAR. The changes will not affect the I

functioning of the fire protection program, which will be maintained pursuant to the operating license. No changes will be made to the program that conflict with the requirements of the operating license.

2) Create the possibility of a new or different kind of accident from any previously evaluated oecause:

, The proposed changes to the Facility Operating License and the

! Technical Specifications represent an administrative shifting of responsibility for the Fire Protection Program Requirements from the Technical Specifications to the UFSAR. The proposed changes do not affect the accident analysis or the operation or function of any safety-related equipment since the Fire Protection Program requirements will continue to be maintained. No new modes of operation are introduced

• these proposed changes. Therefore, the proposed changes do not create the possibility of a new or different kind of accident

from any previously evaluated.

3) Involve a significant reduction in the margin of safety because:

The deletion of the Fire Protection Technical Specifications and incorporation of these provisions into the UFSAR does not change the level of fire protection in the plant.

Additionally, controls added by the standard license condition and the 10 CFR 50.59 criteria will ensure future changes to the Fire Protection Program are properly evaluated.

Therefore, the proposed changes do not involve a significant reduction in the margin of safety.

ENVIRONMENTAL ASSESSMENT EVALUATION PROPOSED SPECIFICATION SECTION 3.12/4.12 FIRE PROTECTION SYSTEMS Commonwealth Edison has evaluated the proposed amendment in accordance with-the requirements of 10-CFR 51.21 and-has-determined that the amendment meets the' requirements for categorical- exclusion as specified by 10 CFR 51.22 (c) (9) .

Conimonwealth Edison has determitmd that the amendment involves no significant hazards consideratisn, there is no significant change in the types or significant inc: aase -in the amounts of any effluent that may be released of fsite, and there is no significant

-increase in-' individual 1or cumulative occupational radiation exposure.

The proposed amendment-does not modify the existing facility and does not involve any new operation of the plant. The: proposed deletion of the Fire Protection _ Technical Specifications and incorporation of these provisions into the UFSAR does-not change the level of_ fire protection in the_ plant. . As such, the proposed

-amendment does not involve any' change in the type or significant increases in effluents, or increase-individual or cumulative occupational-radiation exposure.-

COMPARISON OF UNIT 1 AND UNIT 2 TECHNICAL BPECIFICATIONS l FOR THE IDENTIFICATION OF TECHNICAL DIFFERENCES l SECTION 3.12/4.12 l FIRE PROTECTION Commonwealth Edison has conducted a comparison review of the-Unit 1 and Unit 2 Technical Specifications to identify I any technical differences in support of combining the Technical Specifications into one document. The intent of the raview was not to identify any differences in presentation style (e.g. table formats, use of capital letters, etc.) or punctuation but rather to identify areas which the Technical Specifications are technically or administratively different.

The review of Section 3.12/4.12, " Fire Protection" revealed the following technl cal differences:

Pace 3.12/4.12-5

_ Unit 1 Technical Specification 3.12.C.2 states, "With a sprinkler system inoperable, establish backup fire suppression equipment and inspect the area twice per shift."

The Unit 2 Tecnnical Specification 3.12.C.2 statas, "With the cable tunnel sprinkler system inoperable, establish a continuous fire-watch with backup fire suppression eguipment for the unprotected area witnin one hour" and Specification 3.12.C.3 states, "With any other sprinkler system inoperable, establish backup fire suppression within one hour and inspect the-area.twice per shift."

Unit 1 Technical Specification 3.12.C.2 does not establish a time to establish backup fire suppression equipment while Unit 2 specifies a one hour period. Based on our historical review of our submittals and NRR approval, the time allowance was proposed for both units but inadvertently omitted in the final approval process.

A continuous fire watch is required only for an inoperable sprinkler system in the Unit 2 cable tunnel. The Unit--I cable tunnel has redundant back-up equipment separate from this area and a twice per shift inspection was deemed acceptable for the Unit 1 cable (
