Attachment Observation Docket No. 72-1040 Holtec HI-STORM UMAX Amendment 6 This observation allows you to start earlier on items that may be asked at a later date.

Observations are not the result of a detailed technical review and may be resolved once staff begins a detailed review. Responses to observations are not required for staff to begin their technical review.

The observation is listed by technical discipline of review.

I. OBSERVATION A. Confinement Evaluation (Co)

OBS-Co-1 Clarify or revise safety analysis report (SAR) section 9.2.4, MPC Closure, step 5 (page 9-17).

SAR section 9.2.4, step 5 states, Examine the MPC for leakage. It is not clear whether this, in context, refers specifically to the MPC lid-to-shell weld, whether aspects from SAR section 9.2.4, step 11.e. should be similarly specified, and whether reference 9.1.2 is used. Note, Interim Staff Guidance (ISG)-18, which is part of NUREG-2215, has been used in the past for the HI-STORM UMAX MPC lid-to-shell weld only, if the criteria for ISG-18 are met.

This information is needed to determine compliance with 10 CFR Part 72.104, 106, and 236(e).
