March 31, 2005 MEMORANDUM TO: Frederick D. Brown, Acting Chief Advanced Reactors and Regulatory Effectiveness Branch Division of Systems Analysis and Regulatory Effectiveness Office of Nuclear Regulatory Research FROM: Les R. Cupidon, Electrical Engineer /RA/
Advanced Reactors and Regulatory Effectiveness Branch Division of Systems Analysis and Regulatory Effectiveness Office of Nuclear Regulatory Research
SUBJECT:
PROGRAM PLAN FOR POWER UPRATE OPERATING EXPERIENCE REVIEW Since June 2002, the extended power uprates (EPUs) have generated increased feedwater flow that have resulted in steam generator dryer failure at Quad Cities Units 1 and 2, and steam dryer cracks and feedwater sampling probes failures at Dresden Units 2 and 3.
These events and associated failures throughout the EPU BWR fleet, such as pipe support structures failures, and other failed internal structures as a result of increased flow-induced vibrations have not all been formally compiled. The attached Program Plan has been developed for gathering information and producing an internal report for the agency documenting the operating experience of BWRs that have had an EPU since 1998. The report will provide an overview on the effects of increased flow-induced vibration on structures, systems and components (SSCs) resulting from EPU operation.
Various agency sources will be searched to gather and compile available operational experience data in SSC failures associated with EPUs. Furthermore, an effort will be made to obtain cooperation with relevant utilities and industry groups such as INPO and EPRI for operating experience information related to the topic not currently available to NRC. Various
F. Brown 2 discussions with NRR contacts have confirmed that at the present date, this RES effort is not being duplicated in NRR and as the study progresses, the project manager will continue to coordinate with other relevant NRC offices.
The draft report will be sent to the other relevant offices for comment. Furthermore, this internal report will be used as a tool to identify and justify any further analyses that would result in a follow-up study.
For questions or additional information on this proposed plan, please contact Les Cupidon, 301-415-6366.

PROGRAM PLAN EXTENDED POWER UPRATE OPERATING EXPERIENCE WORK SCOPE To collect and compile operating experience of boiling water reactor (BWR) power plants that have had an extended power uprate (EPU) with known increased flow-induced vibration effects on plant structures, systems and components (SSCs) and document this experience in an internal report. Ascertain the existence of issues that would require a larger work effort.
STATUS This plan is in the initial phases pending an approval of this Program Plan.
System Applicability: All SSCs that may be affected by increased flow-induced vibration related to an EPU at various BWRs.
Project Manager: Les Cupidon, RES/DSARE/ARREB Program Plan for Power Uprate Operating Experience Review The approach begins with the PM gathering information and reviewing activities to summarize operating experience pertaining to various failures of BWR power plant SSCs as a result of increased flow-induced vibrations associated with EPUs.
Information Gathering and Evaluation with Recommendations Task Resource and Schedule Estimates:
NRC effort: 5 staff-months Contract funds: $0K Duration: 5 months for a final report Task
Description:
The PM will review and compile operational experience data on the effects of increased flow-induced vibration on SSCs in BWRs associated with EPUs. The PM shall coordinate with other relevant NRC offices and obtain comments on the draft internal report.
Task Deliverables: Draft and final internal report on EPU operational experience review.
The draft report will be distributed to other program offices for review and comment, with comments to be addressed as necessary in the final report.
Further assessments if necessary will be completed as a follow-up activity in a separate study.
