SUBJECT:
NUREG-0612, Control of Heavy Loads at Nuclear Power Plants
REFERENCE:
- 1) PSC Letter Warembourg to Johnson dated 6/14/85(P-65210)

Dear Mr. Johnson:
In connection with PSC's Phase I Report for th control of heavy loads at FSV (as requested by NRC in Reference 2 and submitted via Reference 1), PSC has recently identified overhead handling systems which can be excluded by inspection from Phase I/ Phase 11 evaluation.
These handling systems are in addition to the ones listed as excluded in Table 2.1.2-1 of the Phase I report and are grouped according to the basis for exclusion as follows:
- 1) Hoists not required to handle heavy loads, i.e., I ton or more.

- 2) Cranes / Hoists excluded on basis of no spent fuel or heavy load shutdown model equipment within load impact region.

Due to the complexity of detailed walkdowns and document reviews necessary to verify the presence of shutdown equipment below each unique handling system and account for all credible load drop scenarios, PSC is revising the submittal date for the Phase II report to October 15, 1985.
Any questions on this matter should be directed to Mr. M. H. Holmes at (303) 571-8409.
Very truly yours, t
