SUBJECT:
ACRS SCOPING ASSESSMENT OF POTENTIAL UNREVIEWED SAFETY QUESTIONS ASSOCIATED WITH MATERIAL INTERACTIONS FOR TPBAR LTAs
Dear Mr. Schinki:
During your March 7, 1997, briefing of the Advisory Committee for Reactor i
Safeguards (ACRS), questions arose regarding the scope of DOE's analyses supporting irradiation of tritium-producing burnable absorber rod (TPBAR) lead test assemblies (LTAs).
Specifically, the ACRS wanted to know whether DOE's report PNNL-11419, " Report on the Evaluation of the Tritium Producing Bernable Absorber Rod Lead Test Assembly," had considered potential unreviewed safety questions associated with material interactions during design basis accident conditions and neutronic effects of LTAs adjacent to fresh and high burnup fuel assemblies during rod drop accidents.
The ACRS has conducted a preliminary scoping assessment of these concerns and its results are provided in the enclosed memorandum to the staff and ACRS from i
Dr. August W. Cronenberg, ACRS fellow.
You should note that the staff does not usually make reports of this kind, which have not undergone peer review, available outside the Commission.
However, because the information may prove useful to you in determining details of the ACRS's concerns, this memorandum is being provided for your use in accordance with the provisions of the May 22, 1996 joint memorandum of
. understanding between the NRC and DOE.
If you have any questions regarding this information, please contact the project manager, J. H. Wilson, at (301) 415-1108.
Sincerely, i
Merylee Slosson for/
