3.15 CONTROL ROOM FILTER SYSTEM Applicability Applies to the Control Room filter system which is required for the safe operation of the plant.
This system incorporates both HEPA filters and a charcoal adsorber bank.
Objective To provide limiting conditions for operation which ensure the operability of the filter system during plant operation, such that normal operation or accidential plant conditions requiring operation of the system will not result in consequences more severe than those previously analyzed.
Specification 3.15.1 During all modes of operation, except cold shutdown, the Control Room filter system shall be capable of performing its intended function in the required manner, except as described below:
- a.
If the system is determined to be inoperable, it shall be returned to operable status within seven days, or in lieu of any other report, prepare a Special Report which shall be submitted to the Commission within the next 14 days.
This report shall outline the cause of the inoperability, the corrective actions taken, and the plans and schedule for restoring the system to an operable status.
3.15.2 If the system is determined to be inoperable while the reactor is in cold shutdown, the system shall be made operable prior to reactor startup.
Basis Operability of the Control Room filter system ensures that the Control Room will remain habitable during an accidential atmospheric radiation 3.15-1 Amendment No. 45

each refueling outage operation or after every 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> of system operation, whichever occurs first, and following signi ficant painting, fire, or chemical release in any ventilation zone commnicating with the filter system.
- c.
Cold DOP testing shall be performed after each complete or partial replacement of a HEPA filter bank or after any structural maintenance of the filter system housing.
- d.
Halogenated hydrocarbon testing shall be performed after each complete or partial replacement of a charcoal adsorber bank or after any structural maintenance on the filter system housing.
- e.
A uniform air distribution within + 20% across HEPA filters and charcoal adsorbers muat be demonstrated initially and after each major repair or modification to the systems which would affect the air distribution.
4.12.3 The relative humidity of the air processed by the refueling filter system shall be monitored hourly during fuel handling operations.
Basis Pressure drop across the combined HEPA filters and charcoal adsorbers of less than 6 inches of water at the system design flow rate will indicate that the filters and adsorbers are not clogged by excessive amounts of foreign matter.
Pressure drop and fan capacity should be determined a least once per operating cycle to show system performance capability.
The frequency of tests and sample analysis are necessary to show that the KEPA filters and charcoal adsorbers can perform as evaluated under postulated accident conditions.
The charcoal adsorber efficiency test procedures should allow for the removal of one adsorber tray, emptying of one bed from the tray, mixing the adsorbent thoroughly and obtaining at least two samples.
Each sample should be at least two inches in diameter and a length equal to the thickness of the bed.
If test results are unacceptable, all adsorbent in the system shall be replaced 4.12-2 Amendment No. 45
with an absorbent qualified according to Table 5.1 of ANSI/ASME N509-1976.
The replacement tray for the adsorber tray removed for the test should meet the same adsorbent quality.
Tests of the EEPA filters with DOP aerosol shall be performed in accordance to ANSI N101.1.
Any REPA filters found defective shall be replaced with filters qualified pursuant to Regulatory Position C.3.d of Regulatory Guide 1.52.
The Containment Purge filter system is normally run continuously during the entire refueling outage to provide cooling and ventilation and periodically during plant operation to reduce airborne radioactivity leaks inside the containment.
Operation time of the Containment Purge filter system after the fuel handling operation is completed should not be added to the operation time during fuel handling operations for determination of testing and surveillance requirements given in these specifications.
If significant painting, fire, or chemical release occurs such that the HEPA filter or charcoal adsorber could become contaminated from the fumes, chemicals, or foreign material, the same laboratory tests and sample analysis shall be performed as required for operational use.
The deter mination of significant shall be made by the operator on duty at the time of the incident.
Knowledgeable staff members should be consulted prior to making this determination.
The relative humidity of the Containment atmosphere and air downstream of the heaters in the Spent Fuel Building filter system shall be monitored at least hourly to assure that the R.H. is less than 70 percent during fuel handling and Containment Purge filter system operation.

4.15 CONTROL ROOM FILTER SYSTEM Applicability Applies to the fan, associated charcoal adsorber bank, and EPA filters of the Control Room filter system.
Objective To verify that the Control Room filter system will adequately remove radioactivity from the incoming ambient air should there be an accidental radiation release to the atmosphere.
Specification 4.15.1 At least once per operating cycle or after 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> of system operation, whichever coes first, and (1) after structural modi fications on the HEPA filter or charcoal adsorber housing which would adversely affect the air flow distribution and (2) following significant painting, fire, or chemical release in any ventilation zone communicating with the system, the following tests shall be performed:
- a.
Verify that the system flow rate is equal to the design flow rate + 10 percent.
- b.
Verify that the charcoal adsorbers remove > 99 percent of a halogenated hydrocarbon refrigerant test gas when they are tested in-place while the ventilation system is operating at a flow equal to the design flow + 10 percent.
- c.
Verify that the HEPA filter banks remove > 99 percent of the DOP when they are tested in-place in accordance with ANSI N101.1 (1972) while operating the ventilation sys tem at a flow equal to the design flow + 10 percent.
4.15-1 Amendment No. 45
- d.
Verify by way of a laboratory test that the system's carbon demonstrates a methyl iodine removal efficiency of > 90 per cent.
The test shall be conducted in accordance with ANSI N509-1976, Table 5-1, Test 5b. The required carbon samples may be obtained by the following methods:
- 1.
One sample obtained from a test canister designed to ANSI N509-1976. The sample must be at least two inches in diameter and with a length equal to or greater than the thickness of the cell's adsorber bed.
- 2.
Two samples obtained by emptying an adsorber cell and mixing the carbon thoroughly. The samples must be at least two inches in diameter and with a length equal to or greater than the thickness of the cell's adsorber bed.
4.15.2 At least once per operating cycle, the following test shall be performed:
- a.
Verify that the pressure drop across the combined HEPA filters and charcoal adsorber bank is < 6 inches Water Gauge at system design flow rate + 10 percent.
- b.
Verify that on a containment isolation test signal, the system automatically switches into a recirculation mode of operation with flow through the HEPA filters and charcoal adsorber banks.
4.15.3 After each complete or partial replacement of the carbon adsorber bank, perform the tests under Specification 4.15.1b.
4.15.4 After each complete or partial replacement of the HEPA filter bank, perform the tests under Specification 4.15.1c.
4.15.5 The associated fan unit in the Control Room filter system shall be verified operable monthly.
4.15-2 Amendment No. 45
Basis Determination that the system is operating at design flow + 10 percent indicates that the fan is operating at or near the design point on its operating curve.
Operation of the fan at flows significantly different from the design flow will change the removal efficiency of the HEPA fil ters and carbon adsorbers.
The frequency of in-place testing and sample analysis are necessary to show that the HEPA filters and charcoal adsorbers can perform as evaluated under postulated accident conditions.
Any HEPA filters found defective shall be replaced with the filters qualified pursuant to Regulatory Position C.3.d of NRC Regulatory Guide 1.52. If the carbon fails to pass the laboratory test, all adsorbent in the system shall be replaced with an adsorber qualified according to Table 5.1 of ANSI N509-1976.
If significant painting, fire, or chemical release occurs such that the HEPA filters or carbon adsorbers could become contaminated from the fumes, chemicals, or foreign material, the same in-place testing and sample analysis shall be performed as required for operational use.
The deter mination of whether the incident is significant enough to warrant the testing shall be made by the Shift Foreman on duty.
Knowledgeable staff members should be consulted prior to making this determination.
A pressure drop across the combined HEPA filters and charcoal adsorbers of less than 6 inches of water at the system design flow rate + 10 percent will indicate that the filters and adsorbers are not clogged by excessive amounts of foreign matter.
