Attachment Proposed Technical Specification Change Present Wording Reference is made to Pilarim Nuclear Power Station, Unit #1 Technical Specifica-tions, Appendix A, Section 3.12, " Fire Protection."
1.
Item 3.12.E The Limiting Condition for Operation, Surveillance Requirements, and Basa for Item 3.12.0 are changed in their entirety. The existing Item 3.12.D is reproduced below. Refer to Pages 2SSd and 2061 in this Attachment for the proposed Item 3.12.E.
NOTE:
The section number is clso changing. The present CO2 system (3.12.0) is being replaced by Halon (3.12.E).
In a future submittal the Fire Hose Station (presently 3.12.E) will be changed to 3.12.D.

a Bases (Present) 3/4.128. C, D, E FIRE SUPPRESSION SYSirMS The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occur-ring:in any portion of the facility where safety related equipment is located.
The fire suppression system consists of the water system, spray and/or sprinklers, CO2 and fire hose stations. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety related equipment and is a major element in the facility fire protection program.
In the event that portions of the fire suppression system are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the affected equipment can be restored to service.
In the event that portions of the fire suppression water system become inoper-able, alternate backup fire fighting equipment is required to be made avail-able in the affected areas until the 'affected equipment can be restored to 4
service.
In the' event that the fire suppression water system becomes inoperable, imme-diate corrective measures must be taken since this system provides the major fire suppression capability of the plant. The requirement for a twenty-four hour report to the Commission provides for prompt evaluation of the accept-ability of the corrective measures to provide adequate fire suppression capability for the continued protection of the nuclear plant.
t Reason for Change A Halon 1301 fire suppression system will be installed in the cable spreading
- room, replacing the original Carbon Dioxide Gaseous Suppression System. The new system is being installed because the CO2 system failed a discharge performance i
test required by the Safety Evaluation Report to Amendment 35 to the PNPS Operat-i ing License.
The CO2 hose stations in the switchgear rooms at elevations 23' and 37' have been replaced'with a Water Hose Station. This Technical Specification Change will be addressed in future submittals.
Safety Considerations These changes do not present an unreviewed safety question as defined in 10CFR
- 50.59. They have been reviewed and approved by the Operations Review Committee and reviewed by the Nuclear Safety Review and Audit Committee.
Significant Hazards Considerations It has been determined that the amendment request involves no significant hazards consideration. Under the NRC's regulations in 10CFR50.92, this means that opera-tion of the Pilgrim Nuclear Power Station in accordance with the proposed amend-ment wotGd not (1) involve a significant increase in the probability or conse-
quences of an hccident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a mar,in of safety.
The NRC has provided guidance concerning the application of standards for deter-mining whether license amendments involve significant hazards considerations by providing certain examples (48 FR 14870). One example of an amendment that is considered not likely to involve a significant hazards consideration is "...(11) a change that constitutes an additional limitation, restriction, or control not presently included in the technical specifications:
for example a more strigent surveillance requirement..."
Schedule of Change As stated in our letter of May 13, 1943, we expect the NRC to issue the seven submittals as a single amendment.
This amendment will be effective upon our receipt of approval from NRC.
Fee Determination Pursuant to 10CFR170.12, Boston Edison Company proposes these changes as one seg-ment of the Fire Protection submittal, which, when taken as a whole will be classified as a Class III amendment. Accordingly, a check for $4000 will be transmitted with the final segment of this amendment request.

3/4.10A FIRE DETECTION INSTRUMENTATION OPERABILITT 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. Frompt detection of the fires will reduce the potential for damage to safety related equipment ano 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 contincus fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is returned to j
operability.
3/4.123, C, D E FIRE SUPPRESSION SYSTEMS I
The OPERABILITY of the fire suppression systems ensures that adequate fire suppres-sien capability is available to confine and extinguish fires occurring in any portion sfh of the facility where safety related equipment is located. The fire suppression system consists of the water system, spray and/or sprinklers, the Halon System and fire hose stations. The collective capability of the fire suppression systema is adequate to minimize potential damage to safety related equipment and is a major element in the facility fire protection program.
j The surveillance requirements provide assurances that the minimum OPERABILITY require-ments of the fire suppression systems are met, An allowance is made for ensuring a A
cufficient volume of Halon in the Halon storage tanks by verifying the weight UA
-of the tanks.

1 In the event that portions of the fire suppression system are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas i
until the affected equipment can be restored to service.
1 In the event that portiens of the fire suppression water system become inoperable, alternate backup fire fighting equipment is required to'be made available in the effected areas until the affected equipment can be restored to service.
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 requirement for a twenty-four hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provide adequat'e fire suppression capability for the continued protection of the nuclear plant 4 l
