'Ib establish the means_by which the general _ intent _specified_in Reference 1-A thru 1-E are accomplished. Measures shall be Wlemented to define the as-Elilt conficurations of applicable systens and to evaluate damage _ study consequenc_es of high energy lines, if postulated break locations are altered due to as-built support locations.

2.2 SCOPE

'Ihis instruction shall apply to the following piping:

Safety Class Size 1 All sizes 2,3 Iarge Bore ,

2,3,5 High energy lines over 1 inch that were ccrrcuter l analyzed.

2,3,5 Designated piping, regardless of size, (up to and includino the first anchor or terminal connection) that interacts with safety relaTed Large Bore pipe.

Additional pipirg may be as-built verified upon written request to l and approval by the TSABC. 'Ihese additional lines are not i specifically within the scope of this instruction ard may be i processed only as necessary to satisfy particular requirements. 1 2.3 GENERAL PRdGPAM DESCRIPI' ION A package censisting of documents required to describe the as-built
