e General O f f aces: 1945 West ParnaH Road, Jackson, %chegan 49201 * ($1 D 788 0640 August 14, 1980 Mr James G Keppler, Regional Director Nuclear Regulatory Con::21st on Region III 799 Roosevelt Road olen Ellyn, IL 60137 MIDIAND PROJECT IE BULLETIH 79-03A FILE o505 12 LTI 995o2%5*1o SERIAL 94o1 This is a coc:plete response to IE Bulletin 79-03A. We have reviewed the project piping vall thickness calculations and piping documentation at the jobsite to identify all ses=relded SA-312 =aterial in use in safety systems which may be subjected hoop stresses greater than 85% of AS!E III Code-allouable hoop stresses, as required by the subject IE bulletin. The list of material identified is attached. Since all piping identified is installed (no open ends) none of the piping was considered accessible for etching.
If any questions arise, please advise.
