At the present time, the ASME Code Section XI, Division 1, Subsection IWE, requirements for metal containment inservice inspection are not specifically referenced in the Nuclear Regulatory Commission (NRC) Regulations. A review of Subsection IWE is being performed by the Idaho National Engineering Laboratory (INEL) to assist the NRC in evaluating the acceptability of incorporating this Subsection into the NRC Regulations. The impact of Subsection IWE requirement changes compared with the present containment inservice inspection (ISI) requirements contained in Appendix J of the NRC Regulations is discussed. In addition, INEL recommendations for improvements/changes in containment ISI requirements are presented for consideration by personnel of code/standards committees and the NRC staff. For example, quantification of requirements for leak testing of localized areas in pressure boundaries is needed. Paragraph IWE-1221(b) calls out ''testing for leak tightness using a gas medium test such as a Halide Detector test.'' The sensitivity required and acceptance criteria for this test should be specified. Both a bubble solution test and a helium mass spectrometer test are ''gas medium tests'', but their sensitivities could vary by a factor of 10/sup 6/. Development of training programs and qualification requirements for personnel who conduct the Appendix J containment leakage tests are also recommended.
