strains and deflections are within the predefined tolerance of their predicted responses. E. Any reliable system of displacement meters, optical devices, strain gauges, or other suitable apparatus may be used for the measurements. F. If the test pressure drops as a result of unexpected conditions to or below the next lower pressure level, the entire test sequence should be repeated. Significant deviations from the previous test should be recorded and evaluated. G. If any significant modifications or repairs are made to the drywell following, and because of, the initial test, the test should be repeated. H. A description of the proposed acceptance test and instrumentation requirements should be included in the preliminary SAR. I. The following information should be submitted before the performance of the test: 3.8.3-25 Revision 3 - May 2010 i. The numerical values of the predicted responses of the structure which will be measured ii. The tolerances to be permitted on the predicted responses iii. The bases on which the predicted responses and the tolerances were established J. The following information should be included in the final test report: i. A description of the actual test and instrumentation ii. A comparison of the test measurements with the allowable limits (predicted response plus tolerance) for deflections and strains iii. An evaluation of the accuracy of the measurements iv. An evaluation of any deviations (i.e., test results that exceed the allowable limits), the disposition of the deviations, and the need for corrective measures v. A discussion of the calculated safety margin provided by the structure as deduced from the test results For Category I structures inside containment, structures monitoring and maintenance requirements are acceptable if found to be in accordance with 10 CFR 50.65 and RG 1.160. It is important that Category I structures inside containment accommodate inservice inspection of critical areas. The staff considers that monitoring
