DPR-29 3.12/4.12 LIMITING CONDITION FOR OPERATION AND SURVEILLANCE REQUIREMENT BASES The operability of the fire suppressiori systems insures that adequate fire suppression capability is available te confine and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The fire suppression system cons'ists of the water system, sprinklx 0, CO 2 , and fire hose stations. The collective capability of the fire suppression sypems is adequate tc 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 oPder 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 ev et 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 a#fected 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 fire suppression capability of the plant. The requirements for a 24-hour notification to the Commission l ;

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 ensues that fires will be confined or adequately retarded from cpreading to adjacent portions of the facility. ,

This design feature minimizes the possibility of a single fire rapidly involving several areas of the facility 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.

SUMMARY

OE_ CHANGES Twelve (12) changes to the Quad Cities Station Units 1 and 2 Technical Specifications have been identified as a result of the proposed license amendment (6 per unit). The changes are listed below as follows:

1) Eage 3.12/4.12-2 (DPR-29 and 30)

(a) Technical Specification 3.12.B.2., Limiting Condition for Operation (LCO) - Insert the word "an" between the words "With" and "Ince table", so the sentence now reads, "With an inoperable fire pump...."

This change clarifies the LCO as being applicable when one fire pump is inoperable or associated water supply is involved.

(b) 3.12.B.3., LCO - Delete the statement "With no Fire Supprassion Water System operable, within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ;" and replace with "With both fire pumps or their associated water supplies inoperable;"

This change clarlfles the LCO as being applicable when both fire pumps or their associated water supplies are inoperable.

(c) 3.12.B.3.a., LCO - Insert the phrase "within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ." following the word "system" so the sentence now reads, "Establish a backup Fire Suppression System within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ."

This change establishes a timeframe of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months for the LCO during which a backup Fire Suppression Water System must be established.

(d) 3.1'.B.3.b., LCO - This specification is essentially being split into two items, 3.12.B.3.b. and 3.12.B.3.c..

(1) 2.12.B.3.b - Following the words, "Notify the Commission" insert the phrase "within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .", "Notify the Commision within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ."

This change establishes a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months time period during which time the loss of both fire pumps or their associated water supplies must be reported.

n. -- - - .

i (2) 3.12.B.3.c - NEW_ SPECIFICATION - Create a new specification ,

which reads as follows, "Submit a report to the Commission within 30 days pursuant to Specification 6.3.A.1. outlining the

' actions taken, the cause of the inoperability and the plans and schedule for restoring the system to operable status" This change carries forward the remainder of what exists in current Specification 3.12.B.3.b., namely, this change naintains the requirement to submit a report to the Commission within 30 days pursuant to Specification 6.3.A.1.. This is considered to be an administrative change to the Technical Specifications.

2) Egge 3.2/4.2-6. Bases Fifth paragraph, second sentence - Replace the word "report" with "notification", so the sentence now reads, "The requirements for a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months notification to the Commission....".

This change clarifles the bases of the LCO and surveillance requirements in that notification must be made to the NRC within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

ATTACIMENT 3 ZyALUATION_OF SIGNIFICANT HAZARDS CONSIDERAllDti AND DESCRIPTION OF PROPOSED AMENDNENI_JtEQUESI 1

The propsed unendment to DPR-29 and DPR-30 clarifles the reporting requirements with one fire pump or associated water supply inoperable for more than seven days and clarifles the notification and subsequent reporting requirements with both fire pumps or associated water supplies inoperable.

This change is patterned after the fire suppression system reportability found in the BWR Standard Technical Specifications. This change is considered to be a&ministrative in nature and does not represent any change in acceptance criteria or safety margins.

BASIS FOR_ NOT SIGNIFICAMIJiAEARDF CONSIDERAIIDH Commonwealth Edison has evaluated this proposed amendment and determined that it involves no significant hazards consideration. In accordance with the criteria of 10 CFR 50.92(c), a propoced unendment to an operating license involves no significant hazards consideratiore if operation l of the facility, in accordance with the proposed amendment, would not

1) Involve a signiJacant increase in the probability or consequences of an accident previously evaluated becauset (a) The proposed Technical Specification changes only involve clarifica-tion of the reporting requirements for the rire Suppression Water System. Additivnally, the change is patterned after the reportability requirements described in the BWR Standard Tschnical Specifications for the rire Suppression Water System. Such a change is considered to be administrative in nature. Therefore, this does not involve a significant increase in the probability or consequence of an accident previously evaluated.

2) Create the possibility of a new or disferent kind of accident from any accident previously evaluated becauset (a) The proposed Technica. S ecification change does not change the operability requiremence for the rire Suppression Water System.

There are no changes to equipment or operating methods as a result of this change. Therefore, the proposed amendment does not create the possiblity of a new or different kind of accident than previously was evaluated.

a

3) Involve a significant reduction in the margin of safety because (a) The proposed Technical Specification change does not decrease the margin of safety. The proposed amendment does not change the operability requirements of the Fire Suppression Water System. The change merely clarifies the reporting requirements for the Fire Suppression Water System and is patterned after the BWR Standard Technical Specifications. Hence, the changes do not result in a decrease in the margin of safety.

Therefore, since the proposed license snendment satisfies the criteria specified in 10 CFR 50.92, Commonwealth Edison has determined that a no significant hazards consideration exist for these items. We further request their approval in accordance with the provisions of 10 CFR 50.91(a)(4).
