"),, ' ;.s.2 Local Leak De.ion Tests

.. . * *~ a. Te s t (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 psjg.

(a) A full airlock test of either the personnel airlock or the emergency escape air lock is not required following door openings to remove strongbacks or to perform a seal contact check.

( b) A seal contact check shall be performed on the emergency escape airlock doors in 1 ieu of a reduced pressure between the seals test following door openings for strongback removal. Further testing of the emergency escape airlock is not required following verification of an acceptable seal contact check. *

(3) Acceptable methods of testing are halogen gas detection, soap bubble, pressure decay, or equivalent. *

(4) The l oca 1 1eak rate sha 11 be measured for each of the following components:

(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 Criteria (I) The total leakage from all penetrations and isolation valves shall not exceed 0.60 La.

(2) The leakage for an air lock door seal test shall not exceed

0. 023 La.

{3) An acceptable seal contact check consists of grease bead pattern running continuously around the length 6f the seals.

c. Corrective Action (I) If at any time it is determined that 0.60 La is exceeded, repairs shall be initiated immediately.
