Conclusions drawn from recent (2002-2003) events in nuclear power plants. Technical note

This document is the second in a series of CSNI Working Group on Operating Experience (WGOE) technical notes on recent events in nuclear power plants (NPPs). The purpose is to transmit WGOE views to both the NEA Committee on Safety of Nuclear Installations (CSNI) and Committee on Nuclear Regulatory Activities (CNRA) and through them to NEA member countries. The identified safety issues are generic in nature. Consequently, national bodies and nuclear licensees must use their judgment about how to take these issues into account in their own programs of action. The Incident Reporting System (IRS), jointly operated by the NEA and IAEA, has contributed to the promotion of the feedback of lessons learned from operating experiences of NPPs. The IRS has enabled the agencies to perform studies on operating experiences, as well as to engage in other activities such as workshops, specialists meetings, and joint research projects. There are many advantages to sharing of operating experiences worldwide, and thus the NEA and IAEA have held joint meetings for this purpose. The most recent meeting was held in Paris in September-October 2003. The significant events and other operating experience used as material of this note were presented at the joint IRS meeting and / or collected in the tasks supervised by WGOE
