DRESDEN-QUAD CITIES LICENSE RENEWAL INSPECTION PLAN I
PURPOSE This inspection plan specifies methods for implementing Manual Chapter 2516 requirements for activities relating to 10 CFR Part 54 (herein after referred to as the rule) and the Dresden-Quad Cities (D/Q) license renewal inspection program. This plan defines the scope of the inspections planned to verify that D/Qs license renewal program is in compliance with the requirements of the rule and is consistent with Exelon Nuclear (Exelons) license renewal application (LRA) and the staffs safety evaluation of Exelons LRA. The plan also provides guidance for inspection scheduling, inspector training, inspection activities, and resource requirements.
Exelon Nuclears LRA identified the systems and structures that Exelon determined were within the scope of the rule. The enclosures to this plan lists the systems and structures selected for this inspection. The inspection team chose the items, after reviewing the scoping results provided in D/Qs LRA, on the basis of their risk significance, uniqueness to D/Q, and current issues. The scope and depth of inspections of these systems and structures may vary.
II OBJECTIVES The overall objective of this plan is to provide guidance for inspecting the implementation and effectiveness of the programs and activities associated with Exelons license renewal program.
The inspection will verify that there is reasonable assurance that the effects of aging will be adequately managed so that the intended function(s) of structures and components (SCs), for which an aging management review is required, will be maintained consistent with the current licensing basis (CLB) during the period of extended operation. Region III will implement the license renewal inspection plan (LRIP) at D/Q before NRR approves Exelons LRA to verify that Exelon meets the requirements of the rule and has implemented license renewal programs and activities consistent with the rule, the LRA, and the staffs safety evaluation report (SER) on the LRA.
III INSPECTION ACTIVITIES Each inspector will receive basic LRIP training. The inspectors will receive additional training on the D/Q LRA and the staffs safety evaluation of the LRA. The training will be given before the inspections.
Inspection Procedure (IP) 71002, License Renewal Inspections, will be the primary procedure used to inspect Exelons implementation of the requirements of the rule. The latest revision of IP 71002 can be reviewed by accessing http://www.nrc.gov/reading-rm/doc-collections/inspec-manual/inspection-procedure/ip-71002.pdf Attachment 1.
The systems and structures groups to be inspected are identified in the enclosures of this plan. The selection of these systems and structures is based on risk significance and the importance of the safety function performed. The inspection team will verify that Exelon has implemented the scoping and screening process consistent with the rule and Exelons methodology, as described in the LRA submitted by letter dated January 3, 2003. The inspection team will also inspect a sample of the systems and structures listed in the enclosures that Exelon concluded were not within the scope of the rule, in order to verify that there is reasonable assurance that all systems and structures within the scope of 10 CFR 54.4 have been identified.
2.
The implementation of the screening activities required under 10 CFR 54.21(a)(1) will be inspected by reviewing system boundaries on plant drawings, intended functions, and the active/passive and short-/long-lived characteristics of the SCs listed in the enclosures to this plan, within the scope of Exelons aging management review.
3.
The inspection team will also walk down accessible portions of the systems and structures to identify any observable inconsistencies in the scoping and screening activities and any aging effects on the systems and structures that are not covered in the LRA. Aging effects identified by Exelon will be reviewed and evaluated during the NRR technical review. The inspection team will perform a sample audit of related maintenance records of the systems and structures listed in the enclosures to attempt to identify any previously unrecognized aging.
4.
The inspection team will inspect the aging management programs (AMPs), including AMPs where Exelon asserts they are consistent with the Generic Aging Lessons Learned (GALL) report, for approximately half of the aging effects in each of the systems and structures listed in the enclosures. The inspection team will examine records for existing aging management programs to evaluate the programs effectiveness and will review plans for new aging management programs. The inspection team will then document its findings on the effectiveness of the aging management programs to maintain the systems and structures intended function(s) consistent with the CLB for the period of extended operation.
IV INSPECTION SCOPE The D/Q license renewal inspection activities will be implemented through two or three site inspections.
1.
The first inspection will last one week or longer, if necessary, and focus on the scoping and screening processes to verify that they have been implemented consistent with the rule, Exelons methodology, and the staffs safety evaluation of Exelons methodology. This inspection should be performed after the staff has completed its safety evaluation of the scoping and screening methodology, but before the SER is issued. The inspection will verify that there is reasonable assurance that Exelons scoping and screening processes have identified all of the systems, structures, and components for which an aging management review is required consistent with the requirements of the rule.
2.
In the second inspection, the team will spend one week at Dresden, return to the region for one week to review documents, begin to write the inspection report, adjust the inspection plan, and then spend a week at Quad Cities. This inspection will examine existing and proposed aging management programs and past results. To support the NRR review process, the report for the second inspection will be issued before the SER with open items is issued.
3.
If the Regional Administrator decides that open inspection items from the first two inspections warrant a third inspection, the team will follow up on previous inspection activities and inspect Exelon actions on any SER open items requested by NRR. This inspection will also focus on any portion of the LRA updated by the applicant as a result of recent plant modifications. The third inspection report will document the need for any future follow-up inspections.
V INSPECTION RESOURCES The inspection will need the following inspection resources:
1.
Inspectors
One team leader
One regional electrical inspector
One regional mechanical (in-service inspection) inspector
One regional mechanical (systems) inspector
One regional mechanical/structural (piping and support) inspector
One or more support staff from the program office 2.
Skills The inspection team needs a cross-section of skills, including mechanical, material, civil, and electrical engineering skills.
The scope of the third inspection (and, thus, the resources) will depend on how many open issues remain from the previous inspection activities.
