June 21,1994 To: All Holders of the Selected Licensee Commitments Manual SLC 16.9-5 changes the term " fire barriers" to " fire rated assemblies" in order to provide current technical criteria for committed fire barrier selection. Testing requirements were also revised to give allowance for change in appearance of a penetration seal. Emphasis is placed on inoperable penetration seals as determining the basis for conducting additional inspections.

piping and ventilation duct penetration seals) in fire rated assembly penetrations shall be OPERABLE.
APPLICABILITY: At all times.
REMEDIAL ACTION:
a.
With one or more of the above required fire rated assemblies and/or sealing devices inoperable, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> either establish a continuous fire watch on at least one side of the affected assembly, or verify the OPERABILITY of fire detectors on at least one side of the inoperable assembly and establish an hourly fire watch patrol.
TESTING REQUIREMENTS:

If a seal is found degraded to inoperable status, a visual inspection of an additional 10% of each type of sealed penetration shall be made.
This inspect' ion process shall continue until a 10% sample with no inoperable seals is found.
Samples hall be selected such that each penetration seal will be inspected every 15 years.
b.
Each of the above required fore doors shall be verified OPERABLE by inspecting the automatic hold-open, release and closing mechanisms and latches at least once per 6 months, and by verifying:

BASES:
The functional integrity of the fire rated assemblies, including associated penetration seals, ensures that fires will be confined or cdequately retarded so that the following criteria is achieved:
Fire will not damage redundant analyzed Post Fire Safe Shutdown equipment, p)
- Fire will not spread from the balance of plant to the Control complex, (d
x
- Fire will not 'apread from non-safety related areas to safety related areas.
Fire will not spread from non-containment areas to containment areas.
The fire related assemblies and associated penetration seals are a passive element in the facility fire protection program and are subject to periodic inspections.
Fire rated assemblies, including associated penetration seals (fire doors, fire windows, fire dampers, cable, piping and ventilation duct penetration seals) are considered operable when the visually observed condition is not degraded to a point that the assembly cannot perform the function that is intended.
For fire rated assemblies that are questionable, an evaluation shall be performed to determine the cause of any identified abnormal change in appearance or abnormal degradation and the effect of this change on the ability of the fire rated assembly to perform its function.
During periods of time when a fire rated assembly is not operable, either:
(1) a continuous fire watch is required to be maintained in the vicinity of the affected barrier, or (2) the fire detectors on at least one side of the affected barrier must be verified OPERABLE and an hourly fire watch patrol established until the barrier is restored to operable status.
