4.5 CONTAINMENT TESTS (Contd)
(2)
If any periodic integrated leak rate test fails to meet the acceptance criteria, the test schedule applicable to subsequent integrated leak rate tests will be reviewed and approved by the Commission.
- e.
Report of Test Results Each integrated leak rate test will be the subject of a swnmary technical report which will include sununaries of local leak detection tests and leak test of the recirculation heat removal systems.
4.5.2 Local Leak Detection Tests
- a.
Test (1)
Local leak rate tests shall be performed at a pressure of not less than 55 psig.
(2)
Local leak rate tests for checking air lock door seals within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of each door opening shall be performed at a pressure of not less than 10 psig.
(3)
Acceptable methods of testing are halogen gas detection, soap bubble, pressure decay, or equivalent.
(4)
The local leak rate shall be measured for each of the following compo-nents:
(a)
Containment penetrations that employ resilient seal gaskets, sealant compounds, or bellows.
(b)
Air lock and equipment door seals.
(c)
Fuel transfer tube.
(d)
Isolation valves on the testable fluid systems' lines penetrating the containment.
(e)
Other containment components which require leak repair in order to meet the acceptance criterion for any integrated leak rate test.
- b.
Acceptance Criterion The total leakage from all penetrations and isolation valves shall not ex-ceed 0.60L.
a
- c.
Corrective Action (1)
If at any time it is deterinined that 0.60L is exceeded, repairs shall a
be initiated immediately.

4.5 CONTAINMENT TESTS (Contd)
(2)
(3)
If repairs are not completed and conformance to the acceptance criter-ion of 4.5.2.b is not demonstrated within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the reactor shall be shut down and depressurized until repairs are effected and the local leakage meets this acceptance criterion.
If 0.601 is exceeded as a result of performing any between the seals air lockaleakage test, repairs should be initiated immediately to satisfy the local leakage acceptance criteria.
However, excessive leakage from a between the seals leak test does not necessarily mean that the door is improperly sealed.
If repairs are not effected to establish local leak rates less than the test acceptance criteria, a full air lock test shall be performed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of the failed between air lock seal test, or the reactor shall be shut down and depressurized until repairs are effected and local leakage criteria met.
Once the full air lock test is performed, the requirements of Sections 4.5.2.c (1) and (2) shall apply~
- d.
Test Frequency (1)
Individual penetrations and containment isolation valves shall be leak rate tested at a frequency of at least every six months prior to the first postoperational integrated leak rate test and at a frequency of at least every refueling thereafter, not exceeding a two-year inter-val, except as specified in (a) and (b) below:
(a)
The containment equipment hatch and the fuel transfer tube shall be tested at each refueling shutdown or after each time used, if that be sooner.
(b)
A full air lock penetration test shall be performed at six-month intervals.
During the period between the six-month tests when containment integrity is required, a reduced pressure test for the door seals or a full air lock penetration test shall be per-formed within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after either each air lock door opening o
~he first of a series of*openings.
(2)
Each three months, the isolation valves must be stroked to the posi-tion required to fulfill their safety function unless it is estab-lished that such operation is not practical during plant operation.
The latter valves shall be full-stroked during each cold shutdown.
4.5.3 Recirculation Heat Removal Systems
- a.
Test (1)
The portion of the shutdown cooling system that is outside the con-tainment shall be tested either by use in normal operation or hydro-statically tested at 255 psig at the interval specified in 4.5.3.d.
(2)
Piping from Valves CV-3029 and CV-3030 to the discharge of the safety injection pumps and containment spray pumps shall be hydrostatically tested at no less than 100 psig at the interval specified in 4.5.3.d.
