l ADDENDUM TO FL-50/EA-50 HIGH INTEGRITY CONTAINER STAFF EVALVATION-REPORT June 1987 During the final review of the October 1985 Staff Evaluation Report concern was expressed by staff of the Transportation and Certification Branch i
.of NRC's Division of Fuel Cycle and Material Safety that the use of Service i
Level C criteria of ASME Section III, Subsection NE was not appropriate. The l
staff proposed the more conservative Service Level A criteria as more 4
appropriate considering the length of time and corresponding ~ uncertainties associated with the performance period. The NRC concerns are summarized in a letter to NuPac (Ref. 21) and an internal memorandum (Ref. 22).
A series'of
{
discussions between NuPac and NRC staff occurred between December 1985 and February 1986, resulting in submittal by NuPac of several proposed design criteria.
Resolution was reached when NuPac indicated that Service Level A criteria would be utilized.
On October 29, 1986, NuPac documented the strutural revision by submitting
)
a revised proprietary topical report for the FL-50/EA-50 High Integrity Container (Ref. 23). The more conservative requirements of Service Level A j
resulted in minor HIC redesign, mainly evident as an increased thickness to the I
lid. During. January 1987, a non-proprietary version of the report was-delivered to the NRC._ The revised reports presented the analysis and redesign resulting from the criteria of Service Level A as well as changes reflecting NuPac responses to previous'NRC comments.
Based on the review of the revised Topical Report the staff concludes that in addition to the requirements and recommendations of Part 61 and the Technical Position on Waste Form, the conditions for issuance of a final proprietary Topical Report discussed in the October 1985 Staff Evaluation Report have-been satisfied.
Issuance of a final non-proprietary Topical Report should incorporate the October 1985 Staff Evaluation Report and this Addendum.
