1.0 IMTR000CTION 1.1 The structural integrity test (SIT) for the containment structure is performed to demonstrate that t.he containment can
. withstand the postulated internal pressure loads in conformance with Appendix A of 10 CFR 50. The SIT for the Unit I containment will be performed in accordance with the requirements (nonprototype) of USNRC Regulatory Guide 1.136 (Revision 2), ASME Section III. . Division 2 Article CC6000 (1986 edition), and United Engineers and Constructors (UE8C) Specification 9763.006-5.5. The code requires that the containment growth be recorded at intervals during the pressurizing and depressurizing of the containment. The purpose of the growth measurements during the SIT is to demonstrate that the containment response to the pressure load is in agreement with predictions.
2.0 PURPOSE 2.1 The plan addresses the procedure for installation of -the temporary frames used for the support of.the 64 displacement transducers (DCDT's) required for monitoring of the containment g ree.9 3.0 RESMNSIBILITIES 3.1 5IT Contractor (BEL /TES) 3.1.1 Brewer Engineering Laboratories, a unit of Teledyne Engineering Services (BEL /TES), shall design, fabricate or purchase, and deliver to the construction site all temporary

3.3 Construction (UEAC) 3.3.1 Al1 access facilities (i ncl uding 1ighting, power, scaffol ding,' etc.) required for the installation shall be provided by UE&C construction. Construction shall carry out any welding and removal of permanent plant equipment necessary for the installation of the temporary frames.
4.0 METHODS OF INSTALLATION 4.1 The majority of the frames shall be installed using beam clamps or 'C' clamps affixed to existing structures within the containment.
J.. : mes shalI be installed by epoxy bonding to the containment I t v, wherever no alternative method exists. The liner plate steel shall be ground clear of paint and cleaned using a cleaning agent prior to the epoxy bonding. The selected and approved epoxy material shall be mixed and applied in accordance with the manufacturer's g instructions.
