5014896 Attachment 4 Multi-Purpose Canister (MPC) 3.1.1 3.1 SFSC INTEGRITY 3.1.1 Multi-Purpose Canister LCO 3.1.1 The MPC shall be dry and helium filled.
Table 3-1 provides decay heat and burnup limits for forced helium dehydration (FHD) and vacuum drying. FHD is not subject to time limits. Vacuum drying of MPCs may be subject to time limits, from the end of bulk water removal until the start of helium backfill, as shown in Table 3-1.
APPLICABILITY: During TRANSPORT OPERATIONS and STORAGE OPERATIONS.

5014896 Attachment 4 Fabrication Helium Leak Test 5.4 ADMINISTRATIVE CONTROLS AND PROGRAMS 5.4 Fabrication Helium Leak Test At completion of welding the MPC shell to baseplate, an MPC confinement weld helium leak test shall be performed using a helium mass spectrometer. This test shall include the base metals of the MPC shell and baseplate. A helium leak test shall also be performed on the base metal of the fabricated MPC lid. The confinement boundary leakage rate tests shall be performed in accordance with ANSI N14.5 to leaktight criteria. If a leakage rate exceeding the acceptance criteria is detected, then the area of leakage shall be determined and the area repaired per ASME Code Section III, Subsection NB requirements. Re-testing shall be performed until the leakage rate acceptance criterion is met.
