The provision of an appropriate framework for operational safety is provided through the plant management system. This system covers all aspects of plant operations both on day to day and long term basis. In May 1995 the Director General defined the safety and quality assurance policy of the plant. The following is stated in the declaration:
The technical director deputy for operation is in charge of engineering, radiation and fire safety in operation. The plant shift supervisor is charged with engineering, radiation and fire safety on shifty basis. The responsibility for industrial radiological and fire safety within plant department lies with heads of departments. Radiation Protection and Industrial Safety department is responsible for managing activities aimed at safe and healthy labor conditions at the plant, prevention of accidents, limiting personnel exposure to radiation, and control of environmental effects. About 80 specialists are working with radiation protection related problems.
The technical director deputy for operation, the state inspector from VATESI, the deputy head of Nuclear Safety division and the inspector from the Safety and Quality Assurance department inspect performance of the operational personnel daily. Inspection objectives include:
Comments received from plant workers are recorded in the operational record-books. Comments provided by the VATESI state inspector must be recorded in the “Record-Book of VATESI” with an obligatory written confirmation of the plant technical director and the deputy plant technical director for operation. The remarks state scope of the work to be accomplished, the responsible persons and procedures dealing with the completion of these tasks.
Equipment malfunction and significant events occurring at the Ignalina NPP are reported and investigated. The key tasks in the investigation of significant events are as follows:
Heads of workshops and divisions performing the analysis of significant events for normal conditions must take necessary measures for timely preparation of measures as well as measures to eliminate the identified deficiencies in the performance of operative and maintenance personnel, to remove equipment defects, and to improve quality of equipment maintenance. Investigation of workshop malfunctions must be started immediately after occurrence. Identification of primary causes as well as collection of descriptive notes from personnel in charge of equipment operation and personnel who were operating the specific equipment prior to the failure, must be made by the plant shift supervisor, the deputy plant shift supervisor and heads for workshop shifts. Investigations of workshop failures must be completed within 10 days of the occurrence of the failure. Under emergency conditions, investigation time can be extended by the plant technical director, but not for longer than 15 days from the date of the malfunction. The Commission to study malfunctions is established and headed by the workshops head or his deputy for operation. The Commission must investigate the failure and prepare a report. The outcome of investigation and proposed measures must be included in the “ Record-Book for Workshop Malfunctions”. Report copies are distributed to the appropriate affected groups and to the Reliability Group. Proposed measures indicated in the report must approved for future application.
Equipment failure and significant events at the Ignalina NPP are also analyzed by the Safety and Quality Assurance department. When investigations on significant events at the Ignalina NPP are undertaken by the Safety and Quality Assurance department, a “Report on Violation at the Ignalina NPP Operation” is issued in which cases are analyzed and parallel analysis on behavior of the operational personnel is performed. The report must be studied by operational personnel.
Review functions are those involving critical monitoring of the performance of the operating and supporting functions, such as quality assurance and safety review. The responsibility for quality assurance rests with all managers. The Safety and Quality Assurance department is responsible for development and implementation at the Ignalina NPP of the effective quality assurance program. Safety review of operational safety at Ignalina NPP includes activities of
the line organization, supplemented by the Safety and Quality Assurance department and the newly formed plant Safety Committee. Both organizations report directly to the Director General.
At the beginning of 1995 the Safety and Quality Assurance Department was established at Ignalina NPP. The Director General delegated to that department the responsibility for monitoring and evaluation of safety of the plant. The department is responsible for the elaboration and adoption of the safety assurance program for the plant. The department must submit its independent evaluations of plant safety directly to the Director General, and will focus on the requirements set forth in nuclear power engineering and industrial safety standards, regulations, instructions dealing with problems of operation, upgrading, maintenance, testing of plant equipment and systems important for safety. The Safety and Quality Assurance department performs independent safety reviews of specific activities and reviews work completed by workshops, departments and plant services. It suggests revisions and improvements to these organizations. The department is involved in the independent assessment of plant modifications.
The new Ignalina NPP Safety Committee was formally established on February 15, 1996 by the plant Director General, to provide advice to the Director in implementing his basic responsibilities for plant nuclear safety. The Committee is composed of 9 experienced individuals from the plant organization and outside experts. Committee members and the Chairman are appointed by the Director General. The Committee functions as an independent reviewer. It will meet regularly, once a month as a minimum, to discuss safety issues arising from its review of various plant reports and observation of activities. Emergency unplanned sessions will be held if required. Appropriate plant staff will participate to present safety issues. The plant Safety Committee performs more strategic reviews of the plant safety-related activities. The Committee is particularly interested in the following areas:
Safety and Quality Assurance Department functions as Committee secretariat. Formal agendas and protocols with tractable formal recommendations are employed.
