4.3.3 Methods to Detect and Remedy Human Failure
Detection of human failure and taking of measures to prevent such failure in the future is an integral part of the system of investigations of events at nuclear installations and their underying causes reasons. Teams of employees have been established for the purpose at the technical support divisions of NPPs to provide for feedback of events at nuclear installations (NIE). Details of the investigation procedures of events occurring at nuclear installations are described in Section 5.5.3. Below are only certain human factor-related aspects are mentioned.
Members of the feedback group assess the efficiency of the process on a regular basis. The results, together with suggested measures and recommendations are included in annual reports submitted to the NPP management for approval.
A total of 20 NIE due to staff failure were recorded in SE EBO in 1997 (25% of the total number), thereof 11 at NPP V-1 and 9 events at V-2.
The NPP staff is regularly informed on the results of the investigation of NIE reasons, and analyses of these investigations are presented during the training. In addition, such information is also available on the Company's computer network.
Also, application of experience from other countries has a significant effect on the prevention of human factor failures. This goes on at several levels:
- Nuclear Power Plants Bohunice and Mochovce are members of the World Association of Nuclear Power Plants Operators (WANO), where this system has been best developed, also thanks to its connection to the Internet.
- Information from foreign NIE are conveyed via ÚJD from the International Incident Reporting System operated jointly with IAEA and the OECD Nuclear Energy Agency (NEA) OECD.
- NuCNet represents an another important world information network to which operator has connection too.
- Power plant managers regularly meet their counterparts operating WWER units in other countries, within the "WWER Club".
- Exchange of experience between the Bohunice NPP staff and other NPPs abroad: NPP Nogent (France), NPP Grohnde (FRG), on a partnership basis.
- Exchange of experience between NPP Mochovce staff and EdF/France/, NPP Dukovany (Czech Republic) and NPP PAKS (Hungary).
- US Agency for International Development (USAID) supported International Nuclear Safety Program (so-called Lisbon Initiative) oriented towards the development of symptom-oriented emergency procedures, management training and operation control programs.
- Operator and ÚJD employees participation in training courses organized by IAEA, US NRC, Operators Association INPO (USA), the US Department of Energy, EU Member States through PHARE projects etc.
