12. Surveillance Programmes
The surveillance programme includes tightness checks, leak tests of all other systems and
components designed to contain radioactive materials, or continuous testing as
appropriate.
12.2.3. Surveillance of safety systems
The surveillance covers SS&C provided to shut down the reactor and keep it shut down,
to ensure that safety limits are not exceeded either under anticipated operational
occurrences or during initial operation of systems required to mitigate the consequences
of accident conditions. The latter includes:
Protection of primary systems against unacceptable pressure surges (steam
dumping, safety and relief valve actuation, etc.); and
Actuation of protective systems as intended.
The surveillance demonstrates the availability of the protection system, including all
redundant parts, verifies the set points at which actuation occurs and the acceptability of
all response times.
All SS&C with functions that mitigate the consequences of accident conditions should be
subjected to periodic surveillance to demonstrate their availability and effectiveness to the
fullest extent practicable and to detect any degradation of their performance. These
functions include, if applicable, but are not necessarily limited to:
