Code Case N-522 directs the testing for pressure retaining piping that penetrates a containment vessel to be performed in accordance with 10 CFR 50, Appendix J, when the piping and isolation valves that are part of the containment system are Class 2 but the balance of the piping is cutside the scope of Section XI.

The perforr,1ance of the hydrostatic and functional tests, as currently required by Section XI, would result in a substantial hardship to the plant in the form of additional expenditures of funds to perform the tests and additional radiation exposure to the individuals involved in the tests without reailzing a commensurate gain in safety.
