Secpe and Objectives This attach =ent describes the inservice inspectica progra= for Class 2 pressure boundary ec penents of TMI-1.

The objective of the inservice inspection progra= is to provide assurance of the centinuing integrity cf the Class 2 syste: vhile at the same ti=e =ini=1:ing radiation expe-su e to personnel and plant downti=e in the perfer m-ce of the inspec-tions.

II.

Identifica:icn of Class 2 Bound 1 ries The Class 2 boundaries were established in accordance with the IIRC Stan-dard Review Plan Section 3 2.2 (ll/2h/75), E!SI Ir1S.2A (1975) and Regu-latory Guide 1.2o Revisic: 3 Quality Group 3.

The Class 2 systens and beundaries are shown in IS! drawings C300-001 through C300-005 and C300-003 through C300-023 III. Applicable Code Iditien and Addenda In accordance with 10 CFR 50 paragraph 50.55a (b), the applicable Code Ziition and Addenda are the 197h Edition with Addenda through S"--ar 1975.

is vritten in ter=s of the code required ten year inspection interval which started in Septe=ber 197h. In addition, the inspection progra=

is based upcn a forty year service lifeti=e of the unit which ends in Septe=ber, 20lk.

7.

Inseeetien prorrs=

Inservice Inspecticus will be carried out in accordance with ASMZ Sec-tica XI,197h Editien with Addenda through Su==er 1975 and specific in-.
