November 24, 2006 Mr. Mano K. Nazar Senior Vice President and Chief Nuclear Officer Indiana Michigan Power Company Nuclear Generation Group One Cook Place Bridgman, MI 49106 SUBJECT D. C. COOK NUCLEAR PLANT (DCCNP), UNITS 1 AND 2 - REQUEST FOR ADDITIONAL INFORMATION REGARDING REACTOR VESSEL HEAD LIFT IN THE LICENSING BASIS (TAC NOS. MD3046 AND MD3047)
Dear Mr. Nazar:
In a letter dated August 27, 1982, Indiana & Michigan Electric Company (I&M), the former licensee of DCCNP, responded to a letter from the Nuclear Regulatory Commission (NRC) staff dated December 22, 1980, regarding control of heavy loads. On page 9 and Table 2.3.4-c of the enclosure, the licensee referenced a Westinghouse Topical Report, WCAP-9198, Reactor Vessel Head Drop analysis, which evaluated the consequences of dropping a reactor vessel head during refueling operations.
As a result of recent inspection activities involving the subject issue, the NRC staff reviewed the referenced I&M letter against the specific provisions of 10 CFR 50.71, which states, in part, that
[the] submittal shall include the effects of: All changes made in the facility or procedures as described in the FSAR; all safety analyses and evaluations performed by the licensee either in support of approved license amendments, or in support of conclusions that changes did not require a license amendment in accordance with Section 50.59(c)(2) of this part; and all analyses of safety issues performed by or on behalf of the licensee at Commission request [emphasis added]. The updated information shall be appropriately located within the update to the FSAR.
It appears that the August 27, 1982, I&M letter, contained a reactor vessel head drop analysis performed by the licensee at Commission request. Specifically, the I&M letter stated that lifting the reactor head within the bounds set as assumptions in the WCAP-9198 model is safe.
Furthermore, I&Ms letter dated September 22, 2006, Justification for Reactor Vessel Head Lift With Fuel in The Core, continued to rely on the WCAP-9198 model. Accordingly, please either explain in your response to this letter why you believe that your analysis of reactor vessel head drop should not be included in the DCCNP licensing basis (i.e., should not be included in the Updated Final Safety Analysis Report (UFSAR)), or state that you plan to include such in the next update of the UFSAR.
Mr. M. K. Nazar We have previously discussed this information request with Ms. S. Simpson under several occasions. Please respond within 30 days of receipt of this letter. Feel free to contact me if you need clarification on this request for additional information.
Sincerely,
/RA/
