UNITED STATES uOVERNMENT f
Memorandum To Harold L. Price DATE: November 18, 1967 Director of Regulation FROM : Peter A. Morris, Director
!W Division of Reactor Licensing
SUBJECT:
METROPOLITAN EDISON COMPANY'S CONSTRUCTION EXEMPTION REQUEST DOCKET No. 50-289 By letter dated July 19, 1967, the Metropolitan Edison Company requested an exemption from the provisions of Section 50.10(b), pursuant to Section 50.12 of the Commission's rules to permit construction of the tendon gallery for the Three Mile Island Nuclear Station Unit 1 prior to issuance of a construction permit.
The tendon access gallery installation is required in order to accomplish laying of the mud mat and the reinforcing steel for the base slab. The gallery is a reinforced concrete passage located below the containment building but does not function as support for the building. The gallery is provided to permit installation of the containment building pre-stressing tendons and periodic inspection of the tendons.
The applicant's basis for performing the requested construction is that the gallery does not function as a safety feature of the containment building and that delaying of the placing of the gallery would delay the overall construction of the facility.
Our review of the exemption request indicates that although the te.Jon gallery is a functional part of the containment building from the view-y M of installation and inspection of the prestressing tendons, it does not serve as a structural foundation. Further, the geological considerations for the Three Mile Island site have been reviewed and it has been determined that there are no unusual foundation problems. We conclude that installation of the tendon gallery would not present a safety problem, and therefore we have no objection to granting the request.
This request for an exemption is similar to that made by the Duke Power Company which was the subject of my memorandum to you dated July 28, 1967. The Duke Power Company exemption was subsequently issued by letter dated August 25, 1967.
