ENCLOSURE e 7 ATEMENTS OF STAFF POSfTTON YANKEE R0WE PF-1 Fire Door Sooervision (D.1)*
.q Fire doors to safety-related areas or areas posing a fire hazard to safety-related areas should be normally closed and locked or electrically supervised with delayed alann and annunciation in the control room.
PF-2 Electrical Cable Penetration Oualification (D.3)
=
The cable penetration fire barriers should be tested to demon-
~
strate a three-hour rating.
The test should be performed or witnessed by a representative of a qualified independent testing laboratory, and should include the following:
(1) The tests should be performed in accordance with ASTM E-119 and the following conditions.
(2) The cables used in the test should include the cable insula-don materials used in the facility.
(3) The test sampla should be representative of the worst case configuration of cable loading, cable tray arrangement, anchoring and penetration fire barrier size and design. The test sample should also be representative of the cable sizes in the facility.
Testing of the penetration fire barrier in the floor configuration will qualify the fire stop for use
~
in the wall configuration also.
(4) Cables penetrating the fire barrier should extend at least three feet on the unexposed side and at least one foot on the exposed side.
(5) The fire barrier should be tested in both directions unless the fire barrier is symmetrical.
(6) The fire barrier should be tested with a pressure differen-tial across it that is equivalent to the maximum pressure differential a fire barrier in the plant is expected to experience.
(7) The temperature levels of the cable insulation, cable conductor, cable tray, conduit, and fire stop material thould be recorded for the unexposed side of the fire barrier.
"Referencea section in Appencix A to STP 9.5-1.
un f (8) Acceptance Criteria - The test is successful if; (a) The cable penetration fire barr1er has withstood the fire endurance test without passage of flame or t
ignition of cables or, the unexposed side for a period of three hours, and (b) The temperature levels recorced for the unexposed side are analyzed and denonstrate that the maximum tempera-ture is sufficiently below the cable insulation
=
ignition temperature, and (c)- The fire barrier remains intact and does not allow projection of water beyond the ur. exposed surface during the hose stream test.
If previous tests can be shown to meet the above position, the licensee should provide the results of the tests to show that the above position is met.
PF-3 Smoke Detection Systems Tests (E.1)
In situ tests should be conducted with a suitable smoke generation
~
device to verify that the products of combustion from a fire would be promptly detected by installed smoke detectors and that ventilation air flow pattern in the area do not significantly reduce or prevent detection response.
Bench tests should be conducted to verify that smoke detectors will provide prompt response and have adequate sensitivity to the products of I
combustien for the combustibles in the area where smoke detectors are installed.
If any fire detection systems are found to be inadequate, appropriate modifications should be made to provide adequate detect 4on system performance.
i PF-4 Battery Room Ventilation Air Flow Monitor If not presently provided, a ventilation air flow monitor abould be installed in each of the station battery rooms to alarm and annunciate, in the control room, the loss of ventilation air flow.
