b. Abstract of Repairs, Replacements or Corrective Measures Required for Continued Service, Table 2, identifies those items containing flaws or relevant conditions that exceeded Division 1 acceptance criteria shall be provided with the information and format of Table 2. This information is required even if the discovery of the flaw or relevant condition that necessitated the repair/replacement activity did not result from an examination or test required by Division 1. If the acceptance criterion for a particular item is not specified in Division 1, the provisions of IWA-3100(b) shall be used to determine which repair/replacement activities are required to be included in the abstract.

In accordance with ASME Section Xl, IWB-2412(a), IWC-2412, IWD-2412 IWE-2412(a), and IWF-2410(b) and with the exception of the examinations that may be deferred until the end of the inspection interval as specified in Table IWB-2500-1, IWC-2500-1, IWD-2500-1, IWF-2500-1 and IWE-2500-1, including those examinations which NMPNS has requested and received approval in the form of relief request, the required examinations in each examination category have been completed for the First In-service Inspection Period in accordance with Tables IWB-2412-1, IWC-2412-1, IWD-2412-1, IWE-2412-1, and IWF-2410-2.

Drawing shows 1/8" typical clearance between pipe and clamshell plates of restraint. No gap exists on top half of pipe; 1/32" gap exists on bottom half of pipe.

Based on a review of the thermal movements in the pipe stress calculation, S14-81P03 the thermal displacements are insignificant.

As such, there is no impact to pipe stress due to the less than 1/8" "normal" gaps at the support 81 -SC-46. There is also no impact on the ability of 81-SC-46 to perform its seismic restraint function.

This condition does not represent a non-conforming condition.

Gaps referenced on drawing B81-SC-46, SH 2 are shown as "nominal". As such minor variations in the gap measurement are expected. Based on the review of the pipe stress calculation the as-found measurements are acceptable and have no impact on the piping analysis.

B-N-2 B13.30 Reactor Vessel Interior Condition Reports CR-2011-002755, CR-2011-002866 and CR-Attachment Weld - 2013-003335 document the identification of a relevant indication Beyond Beltline Region exceeding the acceptance criteria of IWB-3520.2. CENG re-(Steam Dryer Support inspected the four steam dryer support brackets during the Spring Bracket) 2013 refueling outage using EVT-1 and a qualified UT tool and procedure. All four brackets contained reportable indications using UT. Three of the four brackets contained reportable indications using EVT-1.

The UT and EVT-1 inspections performed during RF022 reported flaws larger than reported RFO21 and identified new indications that were not reported in RFO21.

The supporting Engineering Evaluation concluded that the indications are acceptable for continued service for at least one additional operating cycle. In accordance with IWB-3144(b) the engineering evaluation of the exam results is submitted as an attachment to this Owner's Activity Report.
