l test, the test should be repeated. G. A description of the proposed acceptance test and instrumentation requirements should be included in the preliminary SAR. H. The following information should be submitted before the performance of the test: 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 I. 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 seismic 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 seismic Category I structures inside containment accommodate inservice inspection of critical areas. The staff considers that monitoring and maintaining the condition of the containment internal structures are essential for plant safety. Any special design provisions (e.g., providing sufficient physical access, providing alternative 3.8.3-29 Revision 4 – September 2013 means for identifying conditions in inaccessible areas that can lead to degradation, remote visual monitoring of high radiation areas) to accommodate inservice inspection of containment internal structures are reviewed on a case-by-case basis. Technical Rationale The technical rationale for application of these criteria and/or acceptance criteria to
