scope:

This standard¹⁾ specifies acceptable primary containment leakage rate test requirements. The scope includes

(1) leakage test requirements;

(2) test instrumentation;

(3) test procedures;

(4) test methods;

(5) acceptance criteria;

(6) data analysis;

(7) inspection and recording of test results;

(8) guidance on which components and pathways require testing;

(9) test frequency.

Purpose

This standard provides a basis for determining leakage rates through the primary containment of light water reactor nuclear power plants and for implementation of an acceptable leakage testing program. This standard also provides a basis for determining which containment barriers require leakage testing.

The examples given in various sections of this standard do not contain or modify any requirements. These examples are for illustration only and are provided to clarify the intent of the text. Furthermore, the examples are not meant to be all-inclusive. Examples of alternative methods or exceptions to general requirements do not constitute permission to categorically apply the exceptions. Each alternative or exception needs to be evaluated to determine its validity and its effect.

¹⁾ The current standard, ANSI/ANS-56.8-2020, is hereinafter referred to as "this standard."
