effective volumetric examination, magnetic particle or liquid penetrant examination may be substituted. Examination procedures and acceptance standards should be at least equivalent to those specified as supplementary types of examinations, Paragraph 136.4 in ANSI B31.1-1973. b. All fillet and socket welds should be examined by either magnetic particle or liquid penetrant methods. All structural attachment welds to pressure retaining materials should be examined by either magnetic particle or liquid penetrant methods. Examination procedures and acceptance standards should be at least equivalent to those specified as supplementary types of examinations, Paragraph 136.4 in ANSI B31.1-1973. c. All inspection records should be maintained for the life of the plant. These records should include data pertaining to qualification of inspection personnel, examination procedures, and examination results. 4 For design and classifications for evolutionary and passive BWR main steam piping and components, including those comprising main steam isolation valve leakage hold-up and retention paths, as illustrated in Figure A-1, are as follows: a. The "First Valve" in Table A-1, Item 2 refers to the first normally closed valve. b. The main steam line piping from the outermost containment isolation valve up to the seismic interface restraint should be classified as seismic Category I, as should connecting branch lines up to the first normally closed valve. The seismic interface restraint should provide a structural barrier between the seismic Category I portions of main steam piping in the reactor building and the non- seismic Category I portions of such piping in the turbine building. The seismic interface restraint should be located inside a seismic Category I building. Main steam line piping from the seismic interface restraint up to, but not including, the turbine stop valve (including branch lines to the first normally closed valve) and steam drain line piping from the outermost
