Types of facilities

Class I nuclear facilities

This Standard addresses the design and execution of a nuclear air-cleaning system testing program for Class I nuclear facilities.

These facilities include

a) nuclear reactors;

b) uranium fuel fabrication plants;

c) isotope processing facilities;

d) particle accelerators with a beam energy equal to or greater than 50 MeV; and

e) nuclear waste management facilities.

Other nuclear facilities

Parts of this Standard could also be relevant to the design and execution of a nuclear air-cleaning system testing program for

a) Class II nuclear facilities;

b) institutions operating under the authority of a Nuclear Substances and Radiation Devices licence;

c) facilities that use or store naturally-occurring radioactive materials; and

d) waste nuclear substance licensees.

However, in these situations, the operator of the facility or institution is responsible for determining the applicability and suitability of this Standard in accordance with the terms of the operator's site licence.

Facility lifecycle

This Standard addresses nuclear air-cleaning system testing performed during commissioning, operations, and decommissioning.

Effluent covered under this Standard

This Standard provides information on testing of nuclear air-cleaning systems that remove radioactive particulate matter and iodine species from airborne effluent streams. 

Operating conditions

This Standard provides guidance for the design and execution of a testing program for nuclear aircleaning systems used for

a) normal operations;

b) emergency operation

c) operation following upset, maintenance, engineering, or procedural changes with the potential to affect system performance; and

d) operation following engineering changes that might affect system performance.
