Content:
ices, strain gauges, or other suitable apparatus may be used for the measurements. f. If the test pressure drops due to 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 safety analysis report. i. The following information should be submitted prior to the performance of the test: (i)i. The numerical values of the predicted responses of the structure which will be measured. (ii)ii. The tolerances to be permitted on the predicted responses. 3.8.3-33 DRAFT Rev. 2 - April 1996 (iii)iii. The bases on which the predicted responses and the tolerances thereon were established. j. The following information should be included in the final test report: (i)i. A description of the actual test and instrumentation. (ii)ii. A comparison of the test measurements with the allowable limits (predicted response plus tolerance) for deflections and strains. (iii)iii. An evaluation of the accuracy of the measurements. (iv)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)v. A discussion of the calculated safety margin provided by the structure as deduced from the test results. For steel linear supports of the reactor coolant system, testing and inservice surveillance requirements are acceptable if found in accordance with Subsection NF of the ASME Section III Code, Division 1. Technical Rationale127 The technical rationale for application of these acceptance criteria to reviewing concrete and steel internal structures of steel or concrete containments is discussed in the
