Dear Mr. Ippolito:

This letter is to confirm information provided to NRC in a June 12, 1981 conference call regarding the operational status of Brunswick Unit No. 2 and the existing situation relative to inerting contairsent.

(1) Brunswick-2 reached 15% power level at 10:45 p.m. on June 11, 1981. Technical Specifications require containment to be inerted by 10:45 p.m. on June 12.

(2) Good progress has been made in installing the replace-ment oil-fired boiler which will be used to provide steam to vaporize nitrogen to inert containment. We expect to be able to light-off this boiler by about 1:00 p.m. on June 12, 1981.

(3) If boiler operation is satisfactory, inerting contain-ment would take approximately 10 - 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. This is beyond the Technical Specification 6eadline cf 10:45 p.m. on June 12, 1981.
