EROSION / CORROSION IN NUCLEAR POWER COMPONENTS AND PIPING 1993 NPC EROSION / CORROSION WORKSIlOP SIIERATON VALLEY FORGE IIOTEL Tuesday, February 9,1993
SUMMARY
_j
1.0 INTRODUCTION
l On February 9,1993, an Erosion / Corrosion (E/C) Workshop for high energy piping and components was held at the King of Prussia Sheraton Valley Forge Hotel to discuss the performance of E/C programs at US Nuclear Power Generating Stations. In attendance were engineering, technical, and management personnel from utilities throughout the USA, engineering consulting firms and the United States Nuclear Regulatory Commission (USNRC).
E/C is a form of material degradation caused by the wearing away of the protective oxide film on the surface of the affected material due to mechanical abrasion caused by the impact of collapsing gas bubbles in water, impingement of water droplets in steam, and cavitation caused by the impact of collapsing gas bubbles in the water stream. Each of these mechanisms renders an unoxidized surface and continues the deteriorative effect of oxidation of the surface and reduction of wall thickness.
The potential effect of E/C is to reduce the thickness of the wall containing the fluid and ultimately to reduce the wall thickness dimension below that necessary to sustain the i
structural adequacy of the component. The most predominant area for E/C at nuclear power plants is in the carbon steel piping carrying water and/or steam with limited oxygen, near-geometric irregularities such as valves, elbows, and tees, where changes in fluid velocity i
occur.
E/C detection and control programs are being implemented by many utilities throughout the USA. Methods have been developed which aid in evaluating piping systems. These methods provide for directing the inspection efforts of the utility toward areas where the potential for E/C damage is greatest. Many utilities are using computerized versions of these methods to evaluate the many areas of potentially high E/C such that inspection methods can be focused at those points.
USNRC recognizes E/C as a materials degmdation which is the precursor to failure of piping
.j systems, particularly systems that have been on line for long periods of time with adverse fluid systems behavior (chemical or dynamic). Identification of the degraded areas is i) important for the pro;ection'of public health and safety and to minimize plant transients resulting from pipe failures. Many utilities are sensitive to the need to focus on the effect of E/C and have implemented inspection programs to identify weakened sections of piping. For this reason, the USNRC provided an opportunity, through this workshop, for utilities to
2 exchange ideas related to monitoring programs, inspection methods and practices, and evaluation of data to assess acceptability of the inspected components and provide for corrective action when necessary.
NRC Region I has conducted E/C inspections at several plants to investigate the effectiveness of licensee programs in identifying regions in plant piping system which have experienced wall thinning due to E/C.
As a result of these inspections, it was noted that the effects of E/C were being revealed at some plants. These plants have taken action to repair or replace those piping regions having wall thickness reduction at or projected to be below that required to sustain the design-loadings. The inspections found that these plants have high quality, active E/C programs, although weaknesses or problems were identified. Problems were found in performing inspections, interpretation of results, methods in predicting progression of wall deterioration, and determination of the root causes of high rates of wall thinning. Computer techniques were used at some plants for predicting critical regions for excessive pipe wear due to E/C.
The results of these inspections gave rise to the value of a workshop at which the utilities could exchange information and experience with the three major aspects of E/C programs -
E/C monitoring program scopes, inspection methods and practices, and inspection data evaluation directed toward component acceptability assessment.
2.0 TIIE EROSION / CORROSION WORKSIIOP PROGRAM The E/C workshop program (Attachment A) included overview discussions of E/C at two major utilities by Steve Miltenberger, Vice President and Chief Nuclear Officer, Public Service Electric and Gas Company; and Eric DeBarba, Vice President of Nuclear Engineering Services, Northeast Utilities Service Division; research and development efforts of the Electric Power Research Institute (EPRI) by Bindi Chexal, Electric Power Research Institute; and the viewpoint of USNRC by William T. Russell, Associate Director for Inspection and Technical Assessment.
Following these presentations, three workshops (two of each category of interest) were formed at which the participants discussed their experiences with E/C inspection initiatives.
The three workshop categories included monitoring programs (Groups Al and A2),
inspection methods and practices (Groups B1 and B2), and evaluation of data to assess acceptability of the inspected components and provide for corrective measures (Groups C1 and C2).
At the conclusion of the workshops, the facilitators chosen to lead the six workshop sessions reported the results of their deliberations to the participants. These reports were followed by an overview of the results by the four principal speakers at the workshop.
J
3 At the end of the program, participants were requested to complete critique forms stating j
their impressions of the E/C workshop and the inspection program. These forms'were j
collected and assimilated to provide the evaluation of the workshop results by USNRC Region 1.
i 3.0 PRINCIPAL SPEAKERS Four principal speakers addressed the workshop participants prior to the workshop breakout -
sessions. The speakers provided an overview of the E/C inspection programs from the j
perspective of the regulator, utilities, and utility research organization.
i William T. Russell, Associate Director for Inspection and Technical Assessment, provided l
for the USNRC overview of the E/C inspection programs of the utilities. He emphasized that the integrity of high energy pipc in nuclear power generation systems was an important safety issue with respect to safety system integrity and worker safety, warranting a proactive approach with use of predictive models rather than a reactive approach based on judgement i
and experience. He indicated that E/C is covered by the maintenance rule and failures will l
require formal trending and monitoring. Life extension requests will require that licensees have implemented effective E/C programs.
I Bindi Chexal, Electric Power Research Institute, discussed the background of the E/C (flow assisted corrosion) and the efforts of the Checmate Users Group (CHUG),- the industry group l
organized by EPRI to support development of a family of computerized analyses to develop an industry engineering approach, share industry experience, and provide for education and training and input on technology development. Computer Codes developed under this program were CHEC, CllECMATE, CHEC-NDE, and CHECWORKS.
i" Steve Miltenberger, Vice President and Chief Nuclear Officer, Public Service Electric and Gas Company; and Eric DeBarba, Vice President of Nuclear Engineering Services, Northeast Utilities Service Division discussed the E/C program from the point of view of utilities.
They identified E/C program deficiencies relating to procedures, evaluation, and program oversight. They advocated greater information exchange and improved predictive methods.
It was stated that an effective program would require some 5 to 7 years to develop and i
implement. They indicated that utilities need simpler pipe inspection methods, procedures to simplify using materials less susceptible to E/C, and better regulatory guidance for making-temporary repairs.
i The four speakers provided provocative ideas in support, implementation, and financial perspectives of the E/C program. These motivated the workshop breakout session participants toward fruitful discussion of the E/C issues.

4.0 BREAKOUT WORKSIIOP SESSIONS The Workshop participants, on the basis of their particular interests, joined one of three categories of workshop interest groups. Because of the large number of participants, each interest group was divided into two groups of the same interest. Therefore, there were a j
total of six groups in three interest areas. The discussion for each group was as follows:
Groun Al and A2 (Attachment B) i Groups Al and A2 discussed what erosion / corrosion monitoring program scopes should be designed to cover, and how they are best implemented. As a result of the discussion, it was.
reported by the facilitators that good and optimal practices included inspeedon of high risk lines and selection of components using a combination of analysis, engineering judgement,
.l experience, and risk assessment.
l It was indicated that problems to be avoided included poor communication between operators and E/C evaluators, avoiding E/C evaluation of high risk regions, and basing selection of areas to be examined solely on engineering judgement instead of systematically reviewing the 3
system for components of high E/C susceptibility.
The groups suggested that areas for improvement included developing methods to provide good flow measurement, determination of the lower limit of failure significance of thinned walls, and defining failure under the maintenance rule.
t Group Bl and B2 (Attachment C)
Groups B1 and B2 discussed how inspection activities are implemented in accordance with erosion / corrosion monitoring scopes. As a result of the discussion, it was reported by the facilitators that good and optimal practices included inspection of pumps and valves for E/C l
measurement, using tangential radiography testing (RT) for accuracy on small bore pipe, j
1 verifying wall thickness on receipt of pipe and performing a baseline inspection, and I
providing reference marks on pipe or take photographs of inspection areas to insure returning to same locations for futtre measurements.
Problem areas to avoid included poor calibration of measuring instrumentation, not using the
]
proper calibration block, measuring the wrong component, and concluding that the area
~
adjacent to a weld is thin because of E/C, when it is a counterbore.
A problem area defined for resolution was that of clarification of the maintenance rule as to the impact of failed components, and the level of rejection due to E/C under the maintenance l
rule.
u
i l
i I
5 fnoup C1 and C2 (Attachment D)
Groups C1 and C2 discussed how inspection data are evaluated to ensure that degraded components are identified properly for replacement or repair. Good and optimum practices identified by the group included using RT for inspection and developing multiple sets of data to form a basis for prediction.
The groups indicated that problems to avoid are those related to acceptance of weld repair, not defining significant E/C wear, and lack of procedures describing what actions are required for components that have had excessive E/C wear, but are performing satisfactorily.
Problems requiring solution include development of a consistent set of acceptance criteria, and providing for a set of acceptable engineered temporary pipe repairs.
5.0 FEEDBACK FORMS Input from participants was requested by feedback forms. Review of the input indicated that the workshop was beneficial. Many of the feedback forms provided topics for other potential workshops, including motor-operated valves, maintenance rule, service water system piping, I
IST, small bore piping, and piping repairs. The feedback forms showed general agreement with the findings of the workshop breakout groups as presented in Part 4.0. The forms also indicated that this type of workshop is a good way to present industry and NRC perspectives l
on different issues.
6.0 WORKSIIOP RESULTS AND CONCLUSIONS l
From the level of interest shown by the engineering, technical, and management personnel i
attending the 1993 Erosion / Corrosion Workshop, the active participation on the part of the participants in the combined and six breakout sessions, and the many post-workshop comments received by USNRC, the subject of Erosion / Corrosion is one of considerable significance to both the utilities in providing for means to effectively apply engineering toward the safe and efficient operation of their plants, and to the USNRC charged with i
overseeing the protection of public health and safety.
j i
The four main speakers provided a reflection of their interest in the workshop subject matter from the point of view of utilities, research organizations, and USNRC. Mr. Russell identified the approaches to the E/C problem considered acceptable to the regulator. Mr.
Miltenberger and Mr. DeBarba reflected on the interests, both technical and financial, on the implementation of E/C monitoring programs, and Mr. Chexall identified the technology available to the utilities for comprehensively approaching the E/C monitoring problem.
l
i 6
The presentation of the speakers and prior experiences of participants were preparation for the active participation of the participants in the breakout sessions. They openly discussed the problems encountered by utilities and exchanged suggestions for future developments that would facilitate a more effective E/C monitoring program.
