Subject:
Participate in an International Cooperative Effort Working Group Meeting related to Vendor Oversight, Paris, France.
Dates of Travel and Countries/Organizations Visited:
November 13 - 18, 2016 Nuclear Energy Agency (NEA) Multinational Design Evaluation Program (MDEP) Vendor Inspection Cooperation Working Group (VICWG)
Paris, France Desired Outcome:
The purpose of this trip was:
To collaborate in the area of vendor inspection. This meeting facilitated cooperation in the.area of vendor inspection and established working relationships between key individuals in the MDEP member countries. The activities of the MDEP VICWG provide insights into the U.S.
Nuclear Regulation Commission's (NRC) vendor inspection program based on activities conducted by international nuclear regulatory agencies and supports the leveraging of thos,e activities in support of the NRC oversight of vendors providing parts and services to new re.actor construction.
Results Achieved:
The MDEP VICWG continues to achieve its short-term goals of sharing vendor related information between countries and observing inspections when applicable. As the VICWG moves forward, the group will attempt to increase its interaction with the Committee on Nuclear Regulatory Activities (CNRA) Working Group on Inspection Practices (WGIP), continue to plan for one Multinational inspection every two years in addition to continuing joint inspections (multiple nations inspecting to the regulatory requirements of one country), and witnessing of other regulators' inspections.
Summary of Trip:
A brief summary of the MDEP/VICWG meeting is provided below.
This meeting included members from France, Japan, the Republic of Korea, Finland, Canada, China, the Russian Federation, the United Kingdom and the United States. Sweden, United Offieiel U!e OP'II)

Representatives from the International Atomic Energy Agency (IAEA) and the World Nuclear Association (WNA) were present and made presentations. This was the 181h meeting of this working group.
Regulatory Updates Members in attendance presented updates on issues. Key issues of interest are described below.
Ms. Hanna Kuivalainen of Finland provided a status of regulatory activities at the Finnish Radiation and Nuclear Safety Authority (STUK). Olkiluoto 3 (OL3), Finland's EPR reactor, is expected to load fuel in April 2018 and first criticality in June 2018. STUK received a construction application for a VVER1200, Fennovoima (FH-1), which is under review. Ms.
Kuivalainen reported that there was a valve mix-up during installation at OL3 reactor island.
Over 1000 valves are affected with wrong valve bodies, internals, and actuators installed.
STUK will be making a CONEX report on the issue.
Mr. Eric Desgagne of Canada discussed current regulatory activities at the Canadian Nuclear Safety Commission (CNSC). CNSC recently issued a new CSA standard, N299, QA Requirements for the Supply of Nuclear Components, which is available on the CSA website.
Mr. Desgagne discussed an ongoing investigation on a counterfeit CSA certification on a welding receptacle at Ontario Power Generation (OPG). Foir this case, it is the sticker on the weld receptacle that is potentially counterfeit.
Mr. Ludovic Battista of France provided an overview of vendor inspection activities and related supply chain regulatory activities by French Nuclear Safety Authority (ASN). ASN discussed the Flamanville (FA3) reactor pressure vessel dome anomalies and associated lessons learned. As a result of the ongoing review, ASN requested the licensee, EDF, to perform non-destructive surface carbon measurements; perform ultrasonic non-destructive tests; conduct fast fracture analysis by calculation; perform a chemical and mechanical test program on mock-ups; and adopt operational compensatory measures, limited to the thermal shock on steam generator channel heads. These activities are required to be complete prior to 5 French reactors restarting. ASN described the documentation irregularities identified by AREVA at Creusot Forge. ASN stated that AREVA's review of all of the Creusot Forge files could take up to two years. ASN has identified one example of the hydro test for a French steam generator with documentation irregularities that could have a significant impact on safety. The ASN led multinational inspection of AREVA Creusot Forge will be conducted the week of November 28, 2016. Regulators from six countries, i.e., France, US, UK, Canada, Finland, and China, will be participating in the inspection.
Mr. Stuart Allen of the UK's Office of Nuclear Regulation (ONR) provided a discussion of ON R's first complete year of its newly established Supply Chain Regulation (SCR) Program.
Specifically, ONR commenced vendor inspections (i.e., Costain and Bylor) in February 2016.
These vendor inspections focused on examining the adequacy of supply chain management arrangements for compliance with UK regulation, regulatory expectation and specific technical issues. Provisional vendors targeted based on risk, scope and performance. The UK's inaugural plan for 2016/2017 considered a risk baselining review and will inform future vendor inspection plans.
Ms. Olga Kurchatova of the Federal Environmental, Industrial and Nuclear Supervision Service of Russia (ROSTECHNADZOR) described changes to the Rostechnadzor regulations in the Offieiel U!e OP'II)

While the changes were not considered significant, they dealt operating organization requirements arnd deterministic and probabilistic safety analyses. Ms. Kurchatova also described ROSTECHNADZOR documentation associated with their vendor inspections. Specifically, the result of an inspection of a manufacturer is a completed quality plan which is subsequently forwarded to the nuclear power plant site with a set of accompanying documentation. The accompanying documentation includes 1) a review of the results of design documentation review; 2) statement on the manufacturer's preparedness for equipment production; 3) control notification/conclusion; 4) acceptance inspection notification/conclusion; 5) non-conformity reports; and 6) plan of corrective measures with indication of their implementation.
Mr. Hyunsop Chang of the Korea Institute of Nuclear Safety (KINS) provided an update on licensing and construction in South Korea. During startup testing at Shin Kori (either unit 3 or 4), the unit developed a primary power rate to secontdary power rate mismatch. Based on the new policitcal party in the Korean congress, Mr. Chang speculated that either Shin Hanul Units 3 and 4 or Shin Kori Units 5 and 6 may be the last new builds due the anti-nuclear position in congress. KINS plans to increase its inspection sample to 10% of its vendors; i.e., 50 inspections, in 2017. However, due to inspector resources available, it is not likely that KINS will reach that goal.
Mr. Yusuke Kasagawa of the Nuclear Regulation Authority (NRA), Japan provided an update NRA's activities related to the carbon segregation issues identified in France. NRA has conducted interviews with Japan Casting & Forging Corporation (JCFC), Mitsubishi Heavy Industry (MHI), and its major utilities to get a better understanding of the carbon segregation issues. Japan Steel Works (JSW) has not come under scrutiny because its forging materials are free of positive macro-segregation zones, according to an ASN report. NRA is reviewing the utilities reported results of their investigations into the possibility of carbon segregation in Japan.
Mr. Kasagawa provided the Japanese ordinance and standards for class 1 materials.
Mr. Ding Yihang and Mr. Hu Anzhong of the Chinese National Nuclear Security Administration (NNSA) presented the NNSA vendor inspection program. NNSA licenses their vendors of nuclear safety class equipment design, manufacture, installation, and non-destructive examination services. NNSA, specifically the Northern Regional Office (NRO), also inspects nuclear safety equipment activities both foreign and domestic. NRO also performs nuclear safety culture inspections. Five vendors received this inspection in 2016.
Meeting Details The group reviewed updated tables for inspections conducted under the VICWG protocol and planned inspections for 2017 were discussed. NRC, KINS, ASN, and ONR representatives provided details of their planned inspections for 2017 to help members identify inspections they would like to participate In or receive Information on the outcome. NNSA will provide planned inspections for 2017 when it is released.
The group discussed the results of the MDEP Steering Technical Committee (STC) proposal for the future of VICWG presented by the NEA Technical Secretariat. The Policy Group of the STC decided that it will consider the future transfer of VICWG activities to CNRA when the VICWG activities no longer support design-specific work or when the MDEP framework concludes, currently scheduled for 2022. The group will continue to concentrate VICWG activities on vendor inspection cooperation. In performing this activity, VICWG will share experience and lessons learned to enable the representative to respond to areas of emerging risk (i.e., CFSI, Reverse Offieiel U!e OP'II)
Se11silive l11te111al l11fo1111alio11

Mr. Tim Kobetz of IAEA made a presentation on the recent changes in IAEA standards. GR3 is now GS Part 2, "Leadership and Management for Safety." Additionally, NP-T-3.26 replaced the old TECDOC 1169. The NRG took an action to work with NEA to invite the DOE representative to our April meeting to discuss NP-T-3.26.
Mr. Greg Kaser of WNA discussed the lasted activities of the Cooperation in Reactor Design, Evaluation, and Licensing (CORDEL) and the WNA Supply Chain Working Group. Made up of approximately 170 members of vendors and licensees, WNA works with the industry to standardize design and licensing. CORDEL promotes the deployment of standardized nuclear reactor design whereas the Supply Chain WG supports the nuclear industry in resolving common challenges in the supply chain and monitoring and identifying market trends.
The next meeting of the VICWG will be In Washington, DC, the week of April 4 - 6, 2017 with a visit to Curtiss-Wright EMD in Cheswick, PA on April 7, 2017.
Pending Actions/Planned Next Steps for the NRC:
NRC is the current vice Chair for the VICWG. NRC will continue to participate in Multinational, Joint and Observed inspections. The NRC shared its currently identified inspections and offered them for MDEP participation and is soliciting support for these activities. The NRC committed to sharing its safety culture assessor qualification program, i.e. IMC 1245, Appendix C12, Safety Culture Assessor Training and Qualification Journal, to the members of VICWG. The NRC has committed to participate in the multinational inspection led by ASN at Creusot Forge the week of November 28, 2016.
Points for Commission Consideration/Items of Interest:
The content of this report is likely to be of interest to the Commission.
"On the Margins":
Members of the six countries scheduled to participate in the MDEP VICWG inspection of Creusot Forge had two separate meetings to discuss logistics and inspection planning.
The six participating countries include representatives from ASN, ONR, STUK, NNSA, CNCS, and NRC.
