Abstract
The containment vessel for the JRR-2 (CP-5 type reactor) Building was designed to hold gases and vapors released in the worst possible accident of the reactor. The basic problem, the leak test methods as the condition of accepting the building containment, has been discussed in the previous part of this article(*). In the present report, the following subjects are discussed: 1. the other measuring methods of the air volumes, 2. the variations in the building volume, 3. the best conditions for measurement, 4. the allowable reading errors, and 5. the description of the equipments.
