t ' REACTOR-COOLANT SYSTEM' REACTOR COOLANT SYSTEM HEAD VENTS LIMITING CONDITION FOR OPERATION 3.4.12 All Reactor Coolant System Head vent valves, powered from emergency buses shall be OPERABLE

  • and closed ** for each of the reactor vessel head vent paths.

ApPLICABILITYi HDDES 1, 2, 3, and 4 ACTION:

a. With at least one vent path from the above location OPERABLE and one or more power operated vent.yalves inoperable, STARTUP and/or POWER OPERATION may continue provided the inoperable valve (s) is maintained closed with power removed. Power operation may continue until the next scheduled outage, at which time all-Reactor Coolant System _ vent valves shall be OPERABLE prior to entry into MODE 1. The provisions of Specification 3.0.4 are not applicable.
b. With all vent paths from the above location inoperable maintain the inoperable valves closed with power removed or close the manual isola-tion valves, and restore at least one vent path from the above locations to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE REOUIREFERTS -

4.4.12 Each Reac' tor Coolant System Head vent path shall be demonstrated OPER-ABLE at least once per 18 months by:

1. Verifying the manual isolation valve in the vent path is locked or sealed in the open position.
2. Cycling each valve-in the vent path through at least one complete cycle of full travel from the control room.
3. Verifying flow through the Reactor Coolant System Head vent path to the Pressurizer Relief Tank.

j i

  • For purposes of this Specification, an inoperable vent valve is defined as-a valve which exhibits leakage in excess of Specification 3.4.6.2 limits; or '

cannot be opened and closed on demand, or does not have its normal emergency l power supply OPERABLE.

I i **These. valves may be operated for required venting operations and leak j testing'in MODES 3 and 4.

SURVEILLANCE REOUIREMENTS (Continued) a) Emptying one entire bed from a removed adsorber tray, mixing the adsorbent thoroughly, and obtaining samples at least two inches in diameter and with a length equal to the thic~kness of the bed, or b) Emptying a longitudinal sample from an adsorber tray, mixing the adsorbent thoroughly, and obtaining samples at least two inches in diameter and with a length equal to the thickness of the bed.

e. At least once per 18 months by:
1. Verifying that the pressure drop for the combined HEPA filters and charcoal adsorber banks is less than 5.6 inches Water Gauge while. operating the pressurization filtration system at a fic.w rate of 800 to 1000 cfm.
2. Verifying that on a Containment Isolation Phase B/ Control Room High Radiation test signal, the system automatically closes all the series isolation ventilation system dampers which isolate the control room from the outside atmosphere and the system automatically starts 60 minutes later and supplies air to the control room through the HEPA filters and charcoal adsorber banks.
3. Verifying that on a chlorine test signal from the system auto-matically closes all the series isolation ventilation system dampers which isolate the combined control room from the out-side atmosphere.
4. Verifying that the pressurization filtration system maintains the control room at a positive pressure of > 1/8 inch Water Gauge relative to the outside atmosphere during system operation.
5. Verifying that the heaters dissipate 5 1 0.5 kw when tested in-accordance with ANSI N510-1980.
6. Verifying that a chlorine / control room high radiation / containment t phase B isolation signal will initiate operation of the bottled air pressurization system.
7. Verifying by a partial discharge test from four out of five sub-
  • systems of the bottled air pressurization system at a discharge flow of less than 1000 cfm that the bottled air pressurization system will pressurize the control room to > 1/8 inch Water Gauge relative to the outside atmosphere during system operation.

s. PLANT SYSTEMS 3/4.7.8 SUPPLEMENTAL LEAK COLLECTION AND RELEASE SYSTEM (SLCRS)

LIMITING CONDITION FOR OPERATION

-3.7.8.1 Two SLCRS exhaust air filter trains shall be OPERABLE.

APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

With one SLCRS exhaust air filter train inoperable, restore the inoperable train to OPERABLE status within 7 days or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN witfiin the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE RE0VIREMENTS 4.7.8.1 Each SLCRS exhaust air filter train shall be demonstrated OPERABLE:

a. At least once per 31 days by inititting, from the control room, flow

< through the " standby" HEPA filter and charcoal adsorber train and verifying that the train operates for at least 15 minutes with the heater controls operational.

b. At least once per 18 months and (1) after each complete or partial replacement of a HEPA filter or charcoal adsorber bank, or (2) after any structural maintenance on the HEPA filter or charcoal adsorber housings, or (3) following painting, fire or chemical release in any ventilation zone communicating with the system by:
1. Verifying that the charcoal adsorbers remove > 99.95% of a halo-genated hydrocarbon refrigerant test gas when they are tested in place in accordance with ANSI N510-1980 while operatin,g the ventilation system at a flow rate of.59,000 cfm + 10%.
2. Verifying that the HEPA filter banks remove > 99.95% of the D0P when they are tested in place in accordance with ANSI N510-1980 while operating the ventilation system at a flow rate of 59,000 cfm i 10%.
3.
