General 

This Standard covers once-through high efficiency air-cleaning assemblies for maintaining radioactive particulate and radioiodine releases below licenced limits in nuclear power plants. The Standard identifies and establishes minimum requirements for the design, manufacture, installation, and preoperational acceptance testing for any or all of the following components that make up a high efficiency air-cleaning assembly:

(a) moisture separators;

(b) air heaters;

(c) prefilters;

(d) HEPA filters;

(e) adsorbers;

(f) filter housings;

(g) assembly ductwork and dampers;

(h) testing equipment; and

(i) monitoring equipment for operational parameters.

Figures 1 and 2 schematically illustrate typical high efficiency air-cleaning assemblies.

The extent to which high efficiency nuclear air-cleaning systems are required in nuclear plants must be determined on a case-by-case basis as outlined in CSA Standard N288.3.1.

Applicability in Other Nuclear Facilities

This Standard may be used to specify requirements or provide a guideline for the design of air-cleaning assemblies, containing some or all of the afore-mentioned air-cleaning components, and in other nuclear facilities, such as research reactors, facilities for

(a) fuel manufacturing and reprocessing;

(b) radioactive waste management;

(c) production, research, and handling of radio-nuclides; and

(d) mining and milling of uranium ore.

Limitations

This Standard does not cover

(a) removal of noble gases, gaseous carbon 14, and tritium; and

(b) components outside the air-cleaning assembly such as ductwork, fans, and dampers.

Note: This Standard lists all values in SI (metric) units and contains yard-pound equivalents in parentheses for information only.
