The RCP trip criterion being adopted in the Watts Bar-specific procedures not only assures RCP trip for all losses of primary coolant for which trip is considered necessary, but also permits RCP operation to continue during most non-LOCA accidents.
SI will be used to independently verify operability of the UV and shunt trip devices in response to an automatic reactor trip signal.
Procedures will be revised to require events resulting from inadequate or inaccurate vendor information be reported on nuclear network.
MI-85.6 outlines the periodic maintenance requirements for the RTBs.
Technical standard for RTBs will be issued and MI-99.1 will be written to reflect those recommendations.
Maintenance program will be established after life cycle testing of the shunt trip attachment and the UV trip attachment of the reactor trip switchgear information has been made available.
