Periodic inspection of CANDU nuclear power plant components

1.1
This Standard defines requirements for the periodic inspection of pressure retaining systems, components, and supports that form part of a CANDU nuclear power plant.

Periodic inspection (see Annex A for additional guidance) is considered to include the fluid boundary portions of components and piping, including their supports that comprise

a) systems containing fluid that directly transports heat from nuclear fuel;
b) systems essential for the safe shutdown of the reactor or the safe cooling of the fuel, or both, in the event of a process system failure; and
c) other systems or components whose failure could jeopardize the integrity of the systems described in Item a) or b), or both.

In addition, for components exposed to conditions beyond the known experience base, and where such components constitute part of a vital system, the components may be considered suitable for inclusion in the periodic inspection program, as supplementary inspections.

1.2
This Standard addresses

a) failure aspects;
b) classification of areas subject to inspection;
c) provision for access;
d) inspection techniques and procedures;
e) personnel qualifications;
f) frequency of inspection;
g) responsibilities;
h) documentation;
i) records;
j) evaluation of inspection results;
k) dispositioning; and
l) repair, replacement, and modification requirements.
