Dear Mr. Clark,
Enclosed is a list of bulletproof and watertight doors which are proposed for use as fire doors at Calvert Cliffs Nuclear Power Plant. The list was requested by Mr. R. Eberly (Nuclear Regulatory Commission) during a site visit on July 8, 1982. A report substantiating the suitability of' thase doors as fire doors was transmitted under reference (a).
Reference (b) indicated that hydraulic calculations to confirm the applicability (at CCNPP - Unit 2) of the Southwest Research Institute (SWRI) water curtain test resulta vould be performed by July 30, 1982.
Confirming verbal notification to Mr. D. H. Jaffe and Mr. R. Eberly, these calculations have been performed and are on record at Baltimore Gas and Electric Company.
In no instance was system pressure found to be inadequate to support water curtains as tested by SWRI. All calculations were performed in accordance with the methods and guidelines established for the Unit 1 calculations (previously submitted under references (c) and (d).
If you have any questions, please do not hesitate to contact us.
Very truly yor f'.
