15. Operational Safety
In plant Technical Specification, the LCO, Safety Limits (SL), Limiting Safety System
Settings (LSSS) are specified for safe operation and surveillance requirements. Controls
and procedures ensure that LCO are complied with, that deviations are documented and
reported in an appropriate timely manner, and that appropriate actions are taken. The
responsibilities of the shift supervisor and operators with regard to LCO are clear.
Operating procedures, in particular the operating procedures for the plant operations,
system operations, surveillance tests, administrative controls, etc., as well as supporting
reference material, such as systems descriptions, flow sheets, wiring diagrams, and logic
diagrams are easily available and constantly used. Methods for documenting unusual
observations are established. Check sheets or an equivalent means are used to monitor
and record plant parameters.
Besides procedures for normal operation, emergency operating procedures are available
for abnormal conditions and accidents included in the plant design base. In addition,
procedures for coping with beyond design basis accidents (BDBA) to complement
existing emergency operating procedure (EOP, symptom based procedures) are in place.
All activities that may affect safety and can be planned in advance are conducted in
accordance with established procedures. When activities are proposed that are not
included in the normal procedures, special procedures are written in accordance with
established administrative procedures. Such activities and special procedures are carefully
reviewed for safety implications. The approval of these special procedures follows the
same process as the normal procedures of the plant.
