    Working Group on Inspection Practices (WGIP)

    12th International Nuclear Regulatory Inspection Workshop

    Experience from the inspection of licensee's outage activities including fire protection programmes; event response inspections and the impact on inspection programmes of the Fukushima accident

    7-10 April 2014
    Chattanooga, Tennesseee, USA

    Hosted by United States Nuclear Regulatory Commission

    General information

    The OECD Nuclear Energy Agency (NEA) Committee on Nuclear Regulatory Activities (CNRA) Working Group on Inspection Practices (WGIP) will sponsor the 12th International Workshop on Nuclear Regulatory Inspection Activities on Experience from the Inspection of licensee’s outage activities including fire protection programmes, Event response inspections, and the Impact on inspection programmes of the Fukushima accident. The workshop will be hosted by the United States Nuclear Regulatory Commission (U.S. NRC) in Chattanooga, Tennessee, USA on 7-10 April 2014.


    The main purpose of the workshop is to provide a forum for the exchange of information on regulatory inspection activities. Participants will have the opportunity to meet with their counterparts from other countries and organisations to discuss current and future issues on the selected topics. They will develop conclusions and commendable practices regarding these issues and identify methods to help improve their own inspection programmes.


    The CNRA believes that safety inspections are a major element in a regulatory authority’s efforts to ensure the safe operation of nuclear facilities. Considering the importance of these issues, the Committee established a special working group to address inspection practices. The purpose of WGIP is to facilitate the exchange of information and experience related to regulatory safety inspections between CNRA Member countries. This workshop, along with many other activities performed by WGIP, is directed towards this goal. The consensus from participants at previous workshops, noted that the value of meeting with people from other inspection organisations was the most important achievement.


    The workshop will address the following three (3) main topics concerning experience from inspection activities:

    • Inspection of licensee's outage activities including fire protection programmes
    • Event response inspections
    • The impact on inspection programmes of the Fukushima accident


    A brief overview of the concepts and issues for each of the topics is provided in the following paragraphs. Actual issues to be discussed during the workshop will be generated by the organising committee members based on the responses submitted by participants with their registration forms. This will help ensure that issues considered most important by the workshop participants are covered during the group discussions.

    Inspection of licensee's outage activities including fire protection programmes

    Outages are an important opportunity for licensees to undertake plant maintenance, inspections, modifications and other activities necessary to ensure the continued safety of nuclear power plants (NPPs). Fire protection is one of the important aspects to be considered in the frame of this topic because of the increase of the fire risk and maintenance on fire protection systems. The scope of the workshop is limited to planned NPP routine outages and will include: the consideration of NPP outage work scope; regulatory body (RB) inspection scope; nuclear and fire risk minimisation; resolution of outage findings that may affect start-up; and arrangements for restart of the NPP. The focus of this workshop topic is to identify commendable inspection practices by the RB for gaining confidence that safety will be maintained during an outage, return to service, and the following operating cycle of the NPP.

    Event response inspections

    How RBs respond to events is significant for a variety of reasons. The purpose of this workshop topic would be to exchange information on how RBs respond to significant plant operating events. For the purposes of this workshop an event is defined as an incident that has had significant impact on plant safety. Security and safeguard events, and off-site emergency response, have been excluded from this workshop topic to better focus on reactor safety issues. The workshop topic will thus focus on singular events during normal operations and outages which involve an immediate notification of the RB. The focus of this workshop topic is to identify commendable inspection practices for gaining confidence on responding to significant plant operating events.

    The impact on inspection programmes of the Fukushima accident

    The Fukushima accident had a significant impact on RBs. Many RBs reacted to the accident by reviewing their regulatory framework, licensing requirement, and inspection programmes. The purpose of this workshop topic is to explore how the reviews led to changes in inspection programmes. The focus of this workshop topic is to identify commendable inspection practices by the RB for gaining confidence that safety will be maintained in case of severe accidents.


    The formal workshop sessions will be divided into an Opening Session, Discussion Sessions, Open Discussion Session and a Closing Session. Additionally, informal opportunities will be made available throughout the workshop, for participants to exchange information and communicate on other inspection topics.

    Plenary opening session

    This will include presentations by invited speakers from both regulatory and other organisations. The lead WGIP Facilitator for each topic will introduce the main topics to be addressed during the workshop, based on the responses received to the Participants Survey and WGIP discussions.

    Workshop discussion sessions (3 half-day sessions)

    Participants will be divided into smaller groups to discuss one of three workshop topics. A facilitator and recorder will work with each group to stimulate and encourage discussions. Based on experience at previous workshops each group will remain the same throughout these sessions, although facilitators may be rotated to enhance the exchanges of information. Each group will be expected to develop a list of conclusions and commendable practices for the topics being discussed.

    • Participants should indicate on the registration form, the preferred topic they would like to discuss during these sessions. Every attempt will be made to assign participants to the appropriate discussion group. Again, past experience has shown that groups having the most diverse (e.g., participants from different countries) groupings, have been the most effective.
    • Participants are also requested to list one or two specific issues that they would like to see addressed during the workshop discussion sessions.

    As a result of previous workshops, most participants have commented that advance information is very valuable to the discussions. Therefore, you are kindly requested (and it is highly recommended) that participants supply the following information:

    • A short questionnaire for each topic is available below. Participants are kindly requested to provide brief responses (on their chosen topic and/or all topics) of no more than 2 pages. It is hoped that each participating country will provide responses to each of the topic questionnaires in order to better facilitate and co-ordinate the group discussion sessions. Additionally, those participants can if they wish provide general information (short papers of 1 or 2 pages) on their countries’ inspection practices for each topic.

      1. Inspection of licensee's outage activities including fire protection programmes
      2. Event response inspections
      3. The impact on inspection programmes of the Fukushima accident

    • The responses to the questionnaires must be sent to Ms. Nancy Salgado, e-mail: and received by Thursday, 6 February 2014, such that the session leads will have time to review the responses.

    Open discussion session

    Prior to the closing session an open informal discussion (morning) session will be held. Participants will be given the opportunity to discuss and review all of the workshop topics in an informal setting. This may include a presentation on selected related topics arranged by, USNRC.

    Plenary closing session

    One facilitator from each topic will present the conclusions and proposed commendable practices that were developed by their respective groups. A panel discussion including all facilitators and recorders for the topic will answer questions from the audience. Following the presentations, there will be an open panel discussion on the results of the workshop.


    It is expected that the participation in the workshop will be mainly from regulatory organisations familiar with inspection programmes and activities. This includes inspectors, inspection managers and inspection training officers. The intrinsic value of these workshops has been to people, (i.e., the inspectors) who face these topics in practical situations on a day-to-day basis.


    All presentations, discussions, and meeting documents will be in English.

    Workshop proceedings

    Proceedings from the workshop will be published, and will include papers from the Opening Session, Conclusions and Recommendations from the discussion groups, Summary of panel discussions, and information papers submitted by participants to the workshop.

    Informal sessions

    In order for Participants to be able to communicate and exchange information on other topics of interest, informal sessions will be arranged during lunch periods and following daily sessions. Additionally, a meet and greet and a dinner have been arranged by the USNRC. The preliminary schedule is provided below and a detailed schedule and programme will be transmitted to each participant in advance of the workshop.

    Preliminary schedule of workshop activities

    The following schedule has been developed for the workshop. Participants should note that this schedule is preliminary in nature and is subject to change based on the planning and arrangements currently being prepared by the U.S.NRC. As noted in the table, U.S.NRC will be hosting a meet and greet on Sunday evening, a workshop dinner on Thursday evening and coffee breaks during the workshop.
