data for examinations of welds"A","B", and"C" completed since 1986 identified no degradation." Response: Table 1 below provides specific examination history, nondestructive examination (NDE)methods, coverage, and results data for"A","B", and"C" CRD weld examinations completed since 1986.Drawing 1 D-ISI-RC-011 (Figure 1)has been included with this response in order to provide additional information on the weld locations both in terms of elevation, azimuthal and radial location on the reactor vessel closure head.Question: 3.Regarding page 2 of the relief request, paragraph 2, the second sentence states,"There were no examination limitations reported for these welds." Please clarify this statement.
Does it refer to the accessibility of the welds for examination or that there were no defects in the welds?Response: Table 1 has identified that examinations completed were acceptable to ASME Section XI requirements (no degradation was noted).Examination coverage was in accordance with ASME Section XI requirements with the one exception noted in Table 1 and Figure 2 for a 1987 UT examination for weld CRD-151.In this case, an accompanying liquid penetrant examination was completed providing additional NDE coverage for the small area not examined during the UT examination.
