To establish the neans by which the general intent specified in Reference 1-A thru l-E are acccuplished. Measures shall be inplemented to define the as-built configurations of @plicable systems and to evaluate damage study consequences of high energy lines, if postulated treak locations are altered ie to as-built support locations.

2.2 SCOPE

'Ihis instruction shall @ ply to the following piping:

Safety Class Size i

l' All sizes 2,3 Large Bore 2,3,5 Designated Small Bore (up to and including the first anchcr cr terminal connection) that interacts with i

safety related Large Bore pipe.

Additional piping may be as-built verified upon written request to and @ proval by the TSABC. 'Ihese additional lines are not I

specifically within the scope of this instruction and may be processed only as necessary to satisfy particular requirenents.

2.3 GENERAL PROGRAM DESCRIPTIGI j
