ANS 59.2 – Safety Criteria for HVAC Systems Located Outside Primary Containment

This standard establishes criteria for the design of Heating, Ventilating and Air Conditioning (HVAC) Systems located outside the primary reactor containment of light water reactor (LWR) nuclear power plants that could affect nuclear safety functions.

The radiological release control functions of LWR secondary containment systems are covered in American National Standards for Pressurized Water Reactor Containment Ventilation Systems, ANSI/ANS-56.6-1978 and Boiling Water Reactor Containment Ventilation Systems, ANSI/ANS-56.7-1978, and are not covered in this standard.
