- I REQUEST FOR LICENSE AMENDMENT - VACUUM R OPERABILITY
Dear Mr. Ippolito:
In accordance with the Code of Federal Regulations, Title 10, Parts 50.90 and 2.101, Carolina Power & Light Company hereby requests a revision,to the Technical Specifications for its Brunswick Steam Electric Plant, Unit Nos. 1 and 2.
This change will modify, on a temporary basis, the operability requirements for the suppression pool - reactor building vacuum breakers. The manual valves in these lines will be closed and the opening of the valves will be governed by administrative controls based upon the parameters indicated on the attached Technical Specification revision.
Manual operation is acceptable for these valves due to the lengthy interval after an initiating event required to produce the vacuum conditions of con-cern, and the manual nature of the system which could create those conditions.
This revision is requested only until such time as a suitable modification can be developed and installed to permit this system to operate in an automatic fashion.
I Pages which incorporate this revision are attached with the changes indicated by a vertical bar in the right hand margin.
