MILLSTONE UNIT 1 6-5 07-MP1-005 February 2, 2010

TECHNICAL REQUIREMENTS 6.0 Fire Protection

6.1.5 BASES

1. The OPERABILITY of the fire suppression system ensures adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of Unit 1.

The fire suppression system consists of high pressure fire pumps, water supply tanks, fire hydrants, fire hose stations and distribution piping and valves. The collective capability of the fire suppression system is adequate to minimize potential damage to plant SSCs and is a major element in the facility Fire Protection Program.

2. 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 affected areas until the inoperable equipment is restored to service.
3. In the event the fire suppression water system becomes inoperable, immediate corrective measure must be taken since this system provides the major fire suppression capability of the plant.
4. Cessation of cutting, welding, and grinding in the event of major system impairment will reduce the probability of fire by removing the major ignition source in the decommissioning effort.
5. It is the intent of monthly diesel engine fire pump testing to conduct this test during a different week than electric motor pump testing. Nominal monthly (once per 31 days) and 18 month surveillance requirements are consistent with the Unit 2 and 3 surveillance requirements. The surveillance procedures for each of the three fire pumps are common to Units 1, 2 and 3. (See AR 97026324-03 for additional information).
6. Valve 1-FIRE-71 is non-testable. It is the isolation valve for Fire System piping, which has been removed from the Gas Turbine Building.

MILLSTONE UNIT 1 6-13 08-MP1-007 July 15, 2008

TECHNICAL REQUIREMENTS 6.0 Fire Protection

6.6.5 BASES

1. 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 a radiological hazard in a fire and is an integral element in the overall facility fire protection program.
2. Performance of inspection, testing, minor maintenance or calibration of detectors of detection systems that can be done in (1) hour or less does not require notifications.

This is acceptable because testing personnel would be in the area of lost coverage during this inspection/testing evolution.

Roving fire watches must monitor the area of the device in question, as a minimum, within the specified time frame, plus or minus 25% of the time interval specified in the action statement for periodic roving fire watches. The 25% extension of the time interval specified does not degrade the reliability that results from performing the rove at the specified interval, based on plant experience, and Fire Protection Engineering analysis as documented in technical evaluation M3-EV-02-2005, or
2. Establish a continuous fire watch on at least one side of the barrier, or
3. Temporarily repair the inoperable fire barrier and classify it as temporary.

Temporary repair is acceptable for 30 days. If a permanent repair can not be completed within 30 days, implement Technical Requirement 6.7.3, Action 1.b(1) or 1.b(2) above.

6.7.4 SURVEILLANCE

1. Penetration fire barriers shall be verified to be OPERABLE by a visual inspection:
a. At least once per 18 months for fire dampers.

MILLSTONE UNIT 1 6-15 07-MP1-004 March 14, 2007

TECHNICAL REQUIREMENTS 6.0 Fire Protection

b. At least once per 18 months for fire barrier penetration seals, on at least 10% of the total number of penetration seals. If any of the penetration seals in the inspection sample are found to be inoperable, then an additional 10% sample of the penetration seals shall be visually inspected. Sampling and inspection shall continue until all of the seals in a sample are found OPERABLE or 100% of the seals are inspected.
c. Prior to returning a penetration fire barrier to OPERABLE status following repairs or maintenance.

6.7.5 BASES

The functional integrity of the penetration fire barriers ensures that fires will be confined or adequately retarded from spreading to Unit 2. The penetration fire barriers are a passive element in the facility fire protection program and are subject to periodic inspections.

Temporary barriers are allowed to be maintained for a period of up to 30 days, to allow for a sufficient time for repair.

The surveillance requirements for all fire barriers will be verified OPERABLE on a sample basis. Past inspections of 100% of the fire barriers have resulted in a trend that showed a decreasing number of seal failures. This increased reliability has been attributed to improvements in the fire penetration seal program through increased operating experience with penetration seal material and manufacturers technical data regarding seal degradation over time. Manufacturers data indicates that there is no degradation with age and virtually no maintenance requirements for properly installed seals. Training on proper installation of fire seal material as well as tracking of breached fire seals has also improved the reliability.

Plant design changes receive a fire protection review. This review specifically addresses the need to reinstate any new or existing fire barrier penetration seals as part of the work closeout requirements. This provision provides assurance that maintenance and construction work will not result in non-functional fire barriers. Under the Millstone Unit 1 penetration seal reconciliation program, boundary and barrier maps are now developed and used to ensure plant design changes involving penetration seals/fire barriers receive an appropriate fire protection review and are updated accordingly. Fire Inspection by many groups and agencies provide a random check of penetration seals above and beyond the proposed surveillance requirements of the Fire Protection System Technical Requirements.

Penetration seals are not the last line of defense in preventing a fire from affecting two areas/

zones. Many other fire protection features such as fire detection and automatic suppression systems exist. Random inspections (with additional random inspections when affected fire seals exist) should show a good statistical representation of the general seal population without detracting from the fire protection features at Millstone Unit 1.

Roving fire watches must monitor the area of the device in question, as a minimum, within the specified time frame, plus or minus 25% of the time interval specified in the action statement for periodic roving fire watches. The 25% extension of the time interval specified does not degrade the reliability that results from performing the rove at the specified interval, based on plant experience, and Fire Protection Engineering analysis as documented in technical evaluation M3-EV-02-2005.

LIMITING CONDITION FOR OPERATION:

1. When any of the Unit 1 Systems, Structures, or Components listed on TABLE 1 are affected for any reason such that their ability to meet the requirements of Unit 2 is suspect.
2. Deleted.
3. When any of the Unit 1 Systems, Structures, or Components listed on TABLE 3 are affected for any reason such that their ability to meet the requirements of Unit 3 is suspect.

ACTION:

1. For LCO 1, the Unit 2 SM/US shall be immediately notified.
2. For LCO 3, the Unit 3 SM/US shall be immediately notified.

SURVEILLANCE:

1. None BASIS:
1. The purpose of this section of the Basis is to show how the SSCs and their functions in this section were selected. To be included, each SSC and function had to meet all of the following criteria:
a. Be a Licensing Basis or Design function.
b. Be related to the Configuration Management Plan (CMP).
c. Be Operational in nature.

CMP related is defined as either:

a. Safety related or risk related as defined by the Maintenance Rule Program, or
b. Supporting a Unit 2/Unit 3 CMP related program; Flooding, Appendix R, Fire Protection, Reg. Guide 1.97, Seismic, or High Energy Line Break, or
c. Included in Unit 2/Unit 3 Technical Specifications or TRM.

These SSCs and functions were identified and grouped into this TRM to assist the operators in determining the functional needs of Units 2 and 3.

U1-TRM-07 LEVEL OF USE Rev.10 INFORMATION 3 of 7 12/14/01

BASIS: (Continued)

Licensing Basis functions of a purely design nature are not included. This TRM section is not intended as a source for design information. For further information on the origin of each item in the table, see Reference 5 and Reference 13.

Table 1, "UNIT 1 SSCs THAT SUPPORT UNIT 2 FUNCTION OR LICENSE BASIS" was created from information contained in Unit 2 Technical Evaluation M2-EV-98-0201, Table 3.1-5, "Requirements to Complete Validation of Unit 1 Support." Table 3.1-5 contains both operational and design information. The design information has not been included in Table 1 of this TRM. Additional items have been deleted because they are not relevant. The Technical Evaluation of this TRM section, reference 11, provides details on how Table 1 was constructed.

Table 3, "UNIT 1 SSCs THAT SUPPORT UNIT 3 FUNCTION OR LICENSE BASIS" was created from information contained in Unit 3 Technical Evaluation M3-EV-99-0066, "MP1 Equipment Credited by MP3". Table 3 was constructed from the listing and discussion in Unit 3 Technical Evaluation M3-EV-99-0066 in a format similar to Table 1.

2. CR M1-96-0479 was written to identify the lack of communication between units. The corrective action has been to prepare Operations Manual Section 10.4 (reference 2) and this TRM section relating to this unit interdependence to ensure that communications between the Millstone Units are appropriate and are made using a formalized process.

This will ensure that required notifications and acknowledgments to and from other units are performed appropriately.
