February 28, 2003 MEMORANDUM TO: William D. Travers Executive Director for Operations FROM: Samuel J. Collins, Director Office of Nuclear Reactor Regulation /RA/
Ashok C. Thadani, Director Office of Nuclear Regulatory Research
SUBJECT:
STATUS OF IMPLEMENTATION OF DAVIS-BESSE LESSONS LEARNED TASK FORCE REPORT RECOMMENDATIONS The attached table provides the status of implementation of the Davis-Besse Lessons Learned Task Force Report recommendations as of _________________.
Since the last update, the following milestones have been completed:
Since the last update, there were schedule changes associated with the following milestones:
ATTACHMENT 5
Status of Davis-Besse LLTF Recommendations LLTF Target No. LLTF Recommendation Priority Lead Org. Date Status
- 1. Assessment of Stress Corrosion Cracking 3.1.1(1) Assemble foreign and domestic information High RES(DET) concerning Alloy 600 (and other nickel based alloys) nozzle cracking and boric acid corrosion. Analyze nickel based alloy nozzle susceptibility to stress corrosion cracking (SCC), including other susceptible components, and boric acid corrosion of carbon steel, and propose a course of action and an implementation schedule to address the results.
3.3.2(1) Develop inspection guidance for the periodic High NRR(IIPB) inspection of PWR plant boric acid corrosion control programs.
3.2.2(1) Inspect the adequacy of PWR plant boric acid NRR (IIPB) corrosion control programs.
3.3.4(3) Develop inspection guidance or revise existing High NRR (IIPB) guidance to ensure that VHP nozzles and the RPV head area are periodically reviewed by the NRC during licensee ISI activities.
3.3.4(8) Encourage ASME Code requirement changes for High NRR(DE) bare metal inspections of nickel based alloy nozzles for which the code does not require the removal of insulation for inspections. Also, encourage ASME Code requirement changes for the conduct of non-visual NDE inspections of VHP nozzles.
Alternatively, revise 10 CFR 50.55a to address these areas.
1
LLTF Target No. LLTF Recommendation Priority Lead Org. Date Status 3.1.4(1) Determine if it is appropriate to continue using the Medium RES existing SCC models as a predictor of VHP nozzle PWSCC susceptibility.
3.3.7(6) Determine whether ISI summary reports should be Low NRR (DE) submitted to the NRC, and revise the ASME submission requirement and staff guidance regarding disposition of the reports, as appropriate.
2
LLTF Target No. LLTF Recommendation Priority Lead Org. Date Status
- 2. Assessment of Operating Experience, Integration of Operating Experience into Training, and Review of Program Effectiveness 3.1.6(1) Take the following steps to address the High NRR effectiveness of programs involving the review of (RORP) operating experience: (1) evaluate the agencys capability to retain operating experience information and to perform longer-term operating experience reviews; (2) evaluate thresholds, criteria, and guidance for initiating generic communications; (3) evaluate opportunities for additional effectiveness and efficiency gains stemming from changes in organizational alignments (e.g., a centralized NRC operational experience clearing house);
(4) evaluate the effectiveness of the Generic Issues Program; and (5) evaluate the effectiveness of the internal dissemination of operating experience to end users.
3.1.6(2) Update NRC operating experience guidance NRR documents. (RORP) 3.1.6(3) Enhance the effectiveness of NRC processes for the NRR collection, review, assessment, storage, retrieval, (RORP) and dissemination of foreign operating experience. and RES 3.2.4(1) Assess the scope and adequacy of requirements NRR governing licensee review of operating experience. (RORP) 3.3.4(2) Strengthen inspection guidance pertaining to the NRR periodic review of operating experience. (RORP) 3
LLTF Target No. LLTF Recommendation Priority Lead Org. Date Status 3.3.1(1) Provide training and reinforce expectations to NRC NRR (IIPB) managers and staff members to address the following areas: (1) maintaining a questioning attitude in the conduct of inspection activities; (2) developing inspection insights stemming from the DBNPS event relative to symptoms and indications of RCS leakage; (3) communicating expectations regarding the inspection follow-up of the types of problems that occurred at DBNPS; and (4) maintaining an awareness of surroundings while conducting inspections. Training requirements should be evaluated to include the appropriate mix of formal training and on-the-job training commensurate with experience. Mechanisms should be established to perpetuate these training requirements.
3.3.5(1) Maintain expertise in the subject areas by ensuring NRR (IIPB) that NRC inspector training includes: (1) boric acid corrosion effects and control; and (2) PWSCC of nickel based alloy nozzles.
3.1.2(1) Revise NRC processes to require short-term and Medium NRR long-term follow-on verification of licensee actions to (RORP) address significant generic communications (i.e.,

3.3.7(1) Reinforce expectations for the implementation of Medium NRR guidance in the PM handbook for PM site visits, (DLPM) coordination between PMs and resident inspectors, and PM assignment duration. Rreinforce expectations provided to PMs and their supervisors regarding the questioning of information involving plant operation and conditions. Also, strengthen the guidance related to the license amendment review process to emphasize the need to consider current system conditions, reliability, and performance data in SERs.

The impact of extended operating cycles on the opportunity to inspect inside containment and the lack of inspection focus on passive components should be reviewed. This review should also determine whether the guidance and level of effort are sufficient for inspecting other plant areas which are difficult to access or where access is routinely restricted.
