$Qg PLANT SYSTEMS 3/4.7.10 PENETRATION FIRE BARRIERS LIMITING CONDITION FOR OPERATION l
3.7.10 All fire rated assemblies (walls, floor / ceilings, cable tray enclosures, and other fire barriers) separating safety-related fire areas or separating i
i portions of redundant systems important to safe shutdown within a fire area and all sealing devices in fire rated assembly penetrations (fire doors, fire win-dows, fire dampers, cable, piping, and ventilation duct penetration seals) shall l
be OPERABLE.
j APPLICABILITY: At all times unless otherwise determined that the separation of safety-related fire areas or separating portions of redundant systems important to safe shutdown within a fire area is not required based on the MODE of operation.
ACTION:
a.
With one or more of the above required fire rated assemblies and/or penetration sealing devices inoperable, within 1 hour:
1.
Determine that the fire areas / zones on both sides of the affected fire rated assembly and/or penetration sealing device are monitored by either an OPERABLE fire detection or automatic suppression system at the fire barrier and establish a fire watch patrol that inspects both areas at least once per hour, or 2.
Establish a continuous fire watch on at least one side of the affected fire rated assembly and/or penetration seal, or 3.
Temporarily repair the inoperable fire rated assembly and/or sealing device and classify it as temporary.
All temporary or inoperable fire rated assemblies and/or sealing devices shall be permanently repaired within 30 days, or implement ACTION 1 or 2 above.
b.
The provisions of Specifications 3.0.3 and 3.0.4 are not applicable.
SURVEILLANCE REQUIREMENTS 4.7.10 The above required fire rated assemblies and penetration sealing devices shall be verified to be OPERABLE by a visual inspection:
a.
At least once per 18 months for fire doors and fire dampers, 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 total number of 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 fire rated assembly and/or penetration sealing device to OPERABLE status following repairs or maintenance.
MILLSTONE - UNIT 2 3/4 7-41 Amendment No. 3E, 110
PLANT SYSTEMS BASES In the event 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 adequate fire suppression capability for the continued protection of the nuclear plant.
