Phil, Attached is the draft request for additional information (RAI) from the NRR Radiation Protection and Consequences Branch regarding the Davis-Besse NFPA 805 application. The NRC staff will use this draft RAI during its upcoming onsite audit. The final RAI will be issued after the audit and the questions may be revised based upon the audit findings.

Please let me know if you would like to have a clarification call regarding this draft RAI in advance of the audit.

Thanks, Blake Purnell, Project Manager Plant Licensing Branch III-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission ph: 301-415-1380 Docket No. 50-346

REQUEST FOR ADDITIONAL INFORMATION LICENSE AMENDMENT REQUEST TO ADOPT NATIONAL FIRE PROTECTION ASSOCIATION STANDARD 805 FIRSTENERGY NUCLEAR OPERATING COMPANY DAVIS-BESSE NUCLEAR POWER STATION, UNIT NO. 1 DOCKET NO. 50-346 Radiological Release RAI 01 LAR Appendix E states several times that: A bounding analysis was developed that determined that in the event of a fire the radiological release would not exceed 10 CFR limits.

As part of the NRC staffs audit of licensee documents, the staff reviewed Radioactive Material Release Calculation RP-15-01. However, it is not clear if this calculation is the bounding analysis referred to in LAR Appendix E or if this is the only bounding analysis.

For each bounding analysis referred to in LAR Appendix E, provide the title and a summary of the assumptions, methodologies, and resulting doses of the analysis Radiological Release RAI 02 LAR Attachment E, Table E-1, states that compartment MC-01 should be screened in for analysis of radiological containment and monitoring actions associated with firefighting operations. However, LAR Table E-2 states that compartment MC-01 was screened out and does not provide the results of the engineered controls review for liquid and gaseous effluents associated with firefighting activities.

Clarify whether compartment MC-01 should be screened in for analysis of radiological containment and monitoring actions associated with firefighting. If so, provide the results of the engineered controls review for compartment MC-01.
