44h 4.1.6 PRESSURIZER RELIEF VALVES APPLICABILITY:
Applies to the power operated relief valves (PORVs) and their associated block valves for MODES 1, 2 and 3.
OBJECTIVE:
To ensure the reliability of the PORVs and block valves.
SPECIFICATION:
A. Each PORV shall be demonstrated OPERABLE:
- 1. At least once per 31 days by performance of a CHANNEL TEST, which may include valve operation, and
- 2. At least once per 18 months by performance of a CHANNEL CALIBRATION.
B. Each block valve shall be demonstrated OPERABLE at least once per 92 days by operating the valve through one complete cycle of full travel, unless the block valve is being maintained closed in order to meet the requirements of Specification 3.1.5.A.
C. The backup nitrogen supply for the PORVs and block valves shall be demonstrated OPERABLE at least once per 18 months by transferring motive power from the normal air supply to the nitrogen supply and operating the valves through a complete cycle of full travel.
BASIS:
The power operated relief valves (PORVs) operate to relieve RCS pressure below the setting of the pressurizer code safety valves. These relief valves have remotely operated block valves to provide a positive shutoff capability should a relief valve become inoperable. The air supply for both the relief valves and the block valves is capable of being supplied from a backup passive nitrogen source to ensure the ability to seal this possible RCS leakage path.

4.11 CONTROL ROOM EMERGENCY AIR TREATMENT SYSTEM APPLICABILITY:
Applies to the testing and surveillance of the control room' emergency air treatment system to determine OPERABILITY.
OBJECTIVE:
To ensure that the control room emergency air treatment system will operate effectively if required.
SPECIFICATION:
The control room emergency air treatment system shall be demonstrated OPERABLE:
A. At least once per refueling cycle, by verifying that the pressure drop across the combined HEPA filters and charcoal adsorbers is less than 1.8 inches of water while operating the system at a flow rate of 900 cfm
+/- 10%.
B. At least once per year for standby service or after every 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> of system operation and following significant painting, fire, or chemical release in any ventilation zone communicating with the system, by verifying that:
(1) In-place cold DOP and halogenated hydrocarbon tests on HEPA filters and charcoal adsorbers, at a system flow rate of 900 cfm + 10% show > 99% DOP removal and > 99% halogenated hydrocarbon removal when tested in accordance with ANSI N510-1975.
(2) The carbon adsorber is either replaced with an adsorbent meeting the physical property requirements of Table 5-1 of ANSI N509-1976, or a laboratory carbon sample analysis shows, within 31 days after removal, > 90% radioactive methyl iodide removal when tested in accordance with ASTM D-3803, 1979.
(3) A system flow rate of 900 cfm + 10% is shown when tested in accordance with ANSI N510-1975.
C. At least once per 31 days by initiating, from the control room, flow through the HEPA filter and charcoal adsorbers and verifying that the system operates for at least 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> with the heater(s) on.
D. After each complete or partial replacement of the HEPA filter bank or after any structural maintenance on the system housing by performing cold DOP testing. After each complete or partial replacement of the charcoal adsorbers or after any structural maintenance on the system housing by performing halogenated hydrocarbon testing.
Amendment No.
14, 109
E. At least once per refueling cycle by demonstrating automatic closure of the fresh air intake to the control room.
BASIS:
Pressure drop across the combined HEPA filters and charcoal adsorbers of less than 1.8 inches of water at flow rates near design levels (900 cfm + 10%) indicates that the filters and adsorbers are not clogged by excessive amounts of foreign matter. Pressure drop is determined once per refueling cycle to verify system performance capability.
The frequency of tests and sample analysis are necessary to show that the HEPA filters and charcoal adsorbers can perform as evaluated. The tests are performed at a charcoal residence time consistent with the design of the filter unit (i.e. 1/8 second). The removal efficiencies stipulated are consistent with criteria established in the Final Safety Analysis and subsequent analyses; specifically, laboratory carbon test results shall meet the physical property requirements of Regulatory Guide 1.52 Table 2, and when applicable, all replaced adsorbent shall meet the physical property requirements of Table 5.1 of ANSI N509-1976 in conformance with Regulatory Position C.6.a. of Regulatory Guide 1.52. Any HEPA filters found defective should be replaced with filters qualified pursuant to Regulatory Position C.3.d. of Regulatory Guide 1.52.
Operation of the system for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> every month with the heaters on will demonstrate operability of the system and serve to remove excessive moisture build-up on the adsorber.
Contaminants can be generated by painting, fire or chemical release. The fumes, chemicals or foreign materials produced could contaminate the filters or adsorbent if the release occurs in an area communicating with the system. Conducting the same tests as required at refueling intervals or following a significant release of contaminants in a communicating area, assures that system performance is not degraded.
Amendment No.
