SUMMARY
(Continueon Page 2)
Omaha Public Power District (OPPD) Attendees: Bernie Van Sant, Tom Matthews, and Steve Gebers.
NRC Attendees: Shana Helton, Elizabeth Thompson, and Joe Sebrosky Transnuclear Inc., (TN) Attendees: Jim Axline, Robert Grubb, Jayant Bondre, UB Chopra, Prakesh Narayanan The purpose of the phone call was to resolve question that the staff had regarding OPPD's exemption request dated 6/9/06 (see ADAMS ML061650157 for the exemption request).
In a 6/14/06 phone call the staff committed to'revising a question it had regarding the exemption request. The revised question and OPPD's answer appears below.
- 1) Are the radiological consequences (for both the average on-site worker and the off-site individual) of the "hung load due to crane malfunction" discussed on page 14 of the exemption request bounded by any of the prior accident or off-normal condition analyses discussed in Section M.11 or Section W.11 of the UFSAR?
OPPD answer: Yes, the dose rates for the hung load due to a crane malfunction are bounded by the dose rate for the loss of the neutron shield contained in section W.11.1.4 of the UFSAR. (The updated UFSAR Appendix W is provided in of OPPD's exemption request). The loss of neutron shield analysis contained in W.11.1.4 of the UFSAR postulates a complete loss of the neutron shield and also assumes that the trailer shielding is lost. The dose rates provided in W.11.1.4 of the UFSAR therefore bound the "hung load due to a crane malfunction" scenario.
