1 9 1.0' PURPOSE This procedure states.the requirements for performing a Low i
Pressure Soap Bubb] c Leak Test for LN Type A shipping casks. -The fabrication contractor shall submit for approval detailed leak test procedures.
The purpose of this test will be to check the integrity of welds, threaded fittings, flanges and any other joints where pressure tests below 8 psi are adequate tu meet contractural/ functional requirements.
2.0 APPLICABILITY l
This test shall be performed before painting on all LN Technologies Type A chipping casks prior to acceptance from a fabricator.
Additionally, the test shall be performed yearly as a verification of gasket and gasket seating surfaces integrity.
This soap bubble leak test is sensitive for leak testing where a sensitivity of no greater than 30-3 atm.cm3/sec is required.

CAUTION:
IF THE CASK LEAK TEST IS TO BE CONDUCTED WITH A LINER I
INSIDE THE CASK, LINER SHALL BE VENTED DURING Tile TEST 1
TO PREVENT LINER IMPLOSION.

7.4 Close off or maintain pressure at pressurization location to hold specified pressure in cavity.
4 (m) 7.5 Apply the leak detecting solution to all gasketed areas, U
threads, seal welds, ports or valves by brush or spray.
Inspect for bubbles.
I 7.6 Conduct leak test for 5 minutes.
8.0 ACCEPTANCE CRITERIA 8.1 No bubbles shall be visable to the unaided eye during the S minute test.
4 8.2 If bubbles appear during the test, weld integrity, gasket condition, flange or lid tightness, valv'e position, plug 4
security, etc., shall be checked and the test rerun.
