Info

Regional Basic Professional Training Course (BPTC) on Nuclear Safety Systems exist for keys or other methods for controlling doors to restricted areas, and for unlocking manually operated valves that must be in certain positions for safety reasons or for component isolation, as well as for plugs for protection systems. Control room access is limited and access to the control area is restricted to appropriate personnel. The LCOs of the Tech. Spec. (TS) are observed and adhered to in the control room and deficiencies in a safety system are noted and reported in accordance with the LCOs of the TS requirements. The requirements and procedures for the restart of the plant after a reactor trip or shutdown exist and evaluation of the causes of the shutdown takes place. The requirements and procedures for restart of the plant after refueling or maintenance shutdown are in place, and an evaluation of the readiness of the plant for start‐up is performed. In particular: Required tests have been carried out; Appropriate authorization from the plant management exist; Compliance with the LCOs of the TS have been checked; Modified plant has been adequately tested. There is a mechanism for reporting safety shortcomings and improvements. Staffs communicate their experience to other individuals. Clear failure reporting and work order systems exist. Operators have easy access to them through manual or computerized systems. There are daily meetings to review plant status and failure reports and co‐ ordinate necessary actions. ❙ 858 ❙
15.2.6. Work authorizations ❙ 859 ❙ 15. Operational Safety All work conducted at the plant is planned and executed in a manner that is consistent with the requirements of plant operations, both during power operation and during shutdown. Effective interface between the operations and maintenance groups (including contractors) is essential. After finishing the work, operations and maintenance groups ensure that systems and components affected by the work are tested and returned to a satisfactory operational state. Planning of work, outages, modifications and tests is co‐ordinated to assure that the plant remains in a safe condition at all times and in accordance with the LCO. Typical documents showing work authorization practices are the following: Work authorization procedures; Radiological work permit procedures; Isolation rules for electrical and mechanical equipment; The index of surveillance tests carried out by the operating staff; Procedures governing temporary modifications such as the installation of electrical jumpers or disconnections; The index for the administrative procedures governing temporary modifications, work authorizations, equipment isolations, etc. The operating staff surveillance procedures. Work authorization procedures clearly define the responsibilities related to equipment isolation, post maintenance testing and restoration to service.
