Topical Area Review Checklist INSTRUCTIONS This checklist supplements p;oject instruction PI-MP3-02 and shall be used for performing the review of topical areas for the selected systems. Application and use of this checklist shall be as follows:

1. The checklists consists of five parts; A-Pipe Whip / Jet impingement, B-Missiles, C-Internal Fooding, D-Station Blackout and E-Appendix R Safe Shutdown Analysis.

2. The Lead Verifier shall assign verifier (s) to review each of the 5 topics addressed in the checklist. 1

3. The assigned verifier shall complete the applicable part, sign and date the applicable part and return it to the Lead Verifier.

4. The Lead Verifier shall review each part for proper implementation and for completeness.

The Lead Verifier shall assemble the completed checklist, number the pages sequentially,  :

identify the system in the applicable blocks and shall sign and date the cover sheet.

5. The SRG Lead shall indicate his concurrence the checklist has been completed by signing and dating the cover sheet. )

Xsg Ng Comment

1. Is the system under review a high energy piping system as defined in section 3.6.1.1.2 of the USAR. If no, the review is complete. Ifyes, complete the remainder of section A of the checklist.

2. Have the effects of pipe whip and jet impingement been evaluated in ihe 3.6-X series tables of the USAR. If no, initiate DR. If yes, list tables in the comment section.

3. Are the breaks identified in the USAR 3.6 series tables consistent with the piping analysis. Identify calculations reviewed in comment section.

4. Where pipe rupture restraints were used to prevent the pipe from whipping, have the whip restraints been designed adequately.

Justify response in comment section. Identify applicable break numbers, pipe rupture restraints, and calculations reviewed.

Calculations to be reviewed include analysis which determines pipe mpture loads and analysis qualifying the pipe rupture restraint.

5. Where the pipe is allowed to whip, walkdowns and/or drawing reviews have verified all targets are addressed in the USAR tables and supporting calculations. Providejustification for response in i comment section.

6. Where the pipe is allowed to whip, safety related targets have either been demonstrated by analysis to be capable of withstanding impact or are protected by energy absorbing pipe rupture restraints.

Provide basis for yes response in comment section. Basis should identify analysis reviewed (including qualification of target or

! qualification of restraint).

8. For each postulated break, the distance from the break to the safety related jet impingement targets contained in the US AR and supporting analysis has either been ficM verified or verified by drawing review. Provide basis for response in comment section.

9. Jet intensity and jet load calculations for each target have been reviewed and are correct. Justify response in comment section. _

10. Safety related jet impingement targets have been demonstrated to be capable ofwithstanding thejet impingement forces or has been adequately shielded. Justify response in comment section.

a. Have all potential pressurized missile circes bei evaluated in the internally generated missile evaluation. hi .tify response in comment s%et,

b. For missiles determned to be not credibic, vn.s 16r unto justification provided for concluding gena.d= ot ene!!e is not credible. Justify response in comr.nent shc4.

c. For missiles determined to be credible, were. the eff' e :ts of the missile evaluated and if required, were protection features adequate. Justify response in comment section. _

2. Does the system under review contain high speed rotating machinery. Ifyes, answer questions a, b and c below:

a. Were all potential missiles from rotating equipment addressed in the missile analysis. Justify response in comment sheet,

b. Where the evaluation concluded that missile generation was not credible, was this conclusion substantiated. Justify response in concer. sheet.

c. For credible missiles, were the effects of missiles properly evaluated, and if required, were the protection features adequate. Justify response in comment section.
