GENERAL., PRECAUTIONS
.(:
i.
Personnel designated to make cont @ ment entry under pressure shall be medically certified for work in pressurized air. The maximum pressure to which personnel are expected to be exposed is 14 psig. Medical certification shall be submitted to the Test Supervisor (TS) prior to entry into the containment when pressurized.
2.
General access to the containment shall be prohibited within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> prior to the beginning of pressurization. Access during this period will be at the direction of the Shif t Test Supervisor (STS). In the event of an emergency, concurrence of the shif t supervisor (SS) shall be required prior to entry (in lieu of STS).
3.
When entering under pressure, the maximum pressurization and depressurization rates shall be in accordance with the table in Appendix y'
(i) as applicable.
4.
Prior to personnel entry into containment under pressure, if containment has been sealed for an extended period of time, or if the containment atmosphere could be contaminated, due to nitrogen for example, then the air quality must be checked to verify that the atmosphere is satisfactory for personnel entry. Air quality check should involve checks for 'suf ficient 0, n toxic gases, and Rad-Control evaluation of 2
radioactive airborne concentration.
3.
The containment is a high radiation area whi i lly contaminated air. All dischar e No3tainment shall be treated as potentially contamin tiFcleared by Rad-Control / Plant Chemistry. Discharge permits shall be prepared by Plant Chemistry as necessary.
Rev.3
c b
- 4 '-
STP-M-662-2 6._ - Equipment located within the containment which is not designed to be in
- g-an environment pressurized to at least I pound above the maximum test-pressure, should be either vented or removed from the containment.
This equipment is identified in Appendix (2).
7.
All vessels located within the containment containing supplies of compressed gases at a pressure higher than ILRT test pressure are either to be depressurized or tested to verify leak tightness.
-These vessels and their disposition are listed in Appendix (2).
8.
Closure of containment isolation valves for the ILRT shall be accomplished by normal operation and without preliminary exercising except for those valves which are required to be torqued shut by OP-6.
9.
In the event that a valve is found to be causing an excessive leakage after inspections per sections Ill.B.12 and IV.B.1, the valve shall be repaired and/or isolated at the direction of the STS. If during the f.;
pressurization period excessive leakage occurs through locally testable penetrations or isolation valves to the extent tnat it would interfere with the satisfactory completion of the test, these leakage paths may be isolated and pressurization continued until completion. Local leakage tests shall be performed before and af ter the repair of each isolated l,
leakage path. The sum of the post repaired localleakage rates 3rld the g*Qf % 0 upper confidence level shall be less than 75 p,erceritdf the maximum g b' '
allowable leakage rate, La. Local;1edkdge; rates shall not be subtracted y

'from the test results t5[$s Ci[the acceptability of a test. The t t
k l
termine L
results shall be reported with both the pre and post repair local leakage l
rates, as if two tests had been conducted.
10.
A continuous sequential log of events during the ILRT shall be maintained in Appendix (3).
Rev.3

' STP-M-662-2 :
11.
ESFAS actuation signals keying on containment pressure shall be O
deactivated prior to raising containment pressure. These pressure transmitters may not be isolated by valve alignment and will be in their normal operating valve configuration (2-PT-5313 A,B,C,D; 2-PT-5314 n
A,B,C,D; 2-PT-5315 A,B,C,D).
12.
Treat containment boundary vent path leakage as potentially contaminated until cleared by Rad-Control unless the system for which the leakage is occuring is known not to be contaminated.
13.
The low pressure safety injection pump flow path to the RWT will be isolated. If required, ensure a flow path to provide adequate coolin'g is available to the pump prior to starting.

- 4. Sensor Malfunction II in addition to the above plots the recorded data of individual sensors must also be continuously reviewed. The trend of each sensor should follow the trend of the average. Deviation from the trend may indicate a f aulty sensor.
Sufficient drybulb sensors shall be installed so that no one sensor has a volume fraction greater than 10% during the test.
(Note: Sensors should not be located in close proximity to heat sources or heat sinks. If so located, radiant heat shields should be used.)
At least three dewpoint temperature sensors shall be in operation during the test.
At least one pressure sensor shall be in operation during the test.
At least one flow device shall be operable during the verification test.
In general, the number of sensors that can be lost without having to abort the test will be in accordance with ANS!/ANS-56.8-1981, Section 4.4, and BN-TOP-1 instrument criteria.

SCHEDULE OF EQUIPMENT AND VALVE CONDITIONS l
1.
Eaulpment Protection Requirernents 1.
All equipment located inside the containment has been designed to withstand the pressurization of the containment during the ILRT. To assure that the results of the test are valid the safety injection tanks, pressurizer quench tank, and reactor coolant drain tank shall be vented to the containment atmosphere since any leak to or from the tanks could af fect the leak rate measurements.
2.
The secondary side of the steam generators shall not be vented to the containment in any manner. All valves and connections on the secondary side of the steam generator must be checked to assure that they are positioned to isolate the entire system from the containment. Penetration systems involved are as follows:
Penetration System 17A and 17B Steam Gen. #21 Blowdown 43 A and 43B Steam Gen. #22 Blowdown 21 and 22 Auxillary Feedwater 33 and 34 Feedwater
, e.3 ( +f 35 and 36 Main Steam 11.
Valve / Equipment Alignment
- O The valves for which a position is listed ikthe IL T column on the line-up 1.
sheets in this appendix shall be aligned and tagged prior to the ILRT.
2.
Motor operated valves may be listed by three identifications:
a.
Handswitch (H/S)
Rev. 3 t
. STP-M-662-2 b.
Valve itself i (-
MOV, power supply breaker (Bkr.)
c.
3.
Control valves (CV's) are listed by handswitch only.
4.
. Tags and alignment verification signatures shall be made in the area provided for each means of identification. The line-up sheets and the valve line-up exception list will be the mechanism for documenting configuration.
5.
All valves / equipment listed on the "ILRT position" column shall be positioned as indicated. The valve operator shall initial and date the ILRT tag and the valve line-up sheet. The tags stub will be removed and returned to the STS when the valve / equipment is aligned.
6.
At the direction of the STS, additions or exceptions to the valve / equipment line-up sheets shall be annotated on the valve line-up exception list.
7.
Post-ILRT valve / equipment line-up shall be determined by the Shif t Supervisor af ter completion of the ILRT.
111.
Isolation Logic 1.
The general logic concerning isolation of each cotainment penetration is enclosed in the following summary. Valve positions have been selected to most closely represent design basis accident conditions while maintaining systems sufficiently operable to ensure safe plant shut-down operation, in general, systems are designed with isolation valves which would normally be shut on an isolation signal. Where the sequence of these valves shutting or the loss of non-seismic piping connection to the penetration piping can be reasonably assumed to have exposed the seat and disc of the containment isolation valve directly to containment atmosphere as a result of the l
l postulated DBA, the system piping shall be drained and vented.

L.
If a short duration !LRT is conducted (less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />), the i
acceptance criteria listed below shat! be met in addition to the acceptance criteria in Section 1. above.
The Trend Report based on Total Time calculations shall a.
?
indicate that the magnitude of the calculated leak rate is tending to stabilize at a value less than the maximum allowable leak rate (L ). (Note: The magnitude of the a
calculated leak rate may be increasing s!!ghtly as it tends to stabilize. In this case the average rate of increase of the calculated leak rate shall be determined from the accumulated data over the last five hours or last twentry data points, which ever provides the most points. Using this l
average rate the calculated leak rate can then be linearly g
extrapolated to the 24th hour data point, if this extrapolated value of the calculated leak rate exceeds 73%
e of the maximum allowable leak rate (L ) then the leak rate a
test is continued.)

c.
The mean of the measured leak rates based on Total Time -
calculations over the last five hours of test or last twenty data points, whichever provides the most data, shall be less i
than the maximum allowable leak rate.
