Subject:
Waterford 3 SES Docket No. 50-382 Licenne No. NPF-38 TNTTIAI, TEST PROGRAM
Reference:
Waterford 1 FSAR, Chapter 14 This nubmittal in made in accordance with 10 CFR 50.59(b) and the licenne condition in Section 2.C.10 of the subject licenne. Reported horowith in a change made to the Waterford 3 Initial Tent Program, as doncribed in reference 1. nn amended through Amendment No. 36 The attached marked-up pagen 14.2-129 (Amendment 34) and 3.9-109 (Table 3.9-19 Amendment 14) of the Waterford 3 FSAR reflects the changn made for tent subncetion 14.2.12.3.17 Piping Thermal Crowth, Vibration, and Shock. A natinfactory evaluation of piping stronnen in main stonm piping after the revined tent will be acceptabla fantend of nn actual inntrumented level 4, trannient monitoring of the main stonm syntem during turhinn trip from 100% power. The vibration tenting constatn of n vinunt innpoetion of the nopportn/ rentraintn on thn main utcam piping nfter turbine trip from 85% power and a connorvativo ovaluntion of the piping ntrannon using thn renults of tho vinunt innpoetion. Thn osaluation of thn renults of the visual innpoetion will alno dotarmfnn if nduttional trannient vihrntion monitoring of the main ntuam lino in required. An additional tranninnt vihrntion monitoring of the ntonm line will be performed if required. Thin change to the initial tent program doen not involvo a changn in the license technical speciftentions or nn unroviewed anfety question.

N I-/MY/ WSES-FSAR-UNIT-3 14.2.12.3.17 PIPIFC THERMAL GROVIF, VIERATION, AND SFOCK 34 14.2.12.3.17.1 Objectives To demonstrate that the essential Fuclear Stear Supply Syster (FSSS) and g balance of plant corponents reet acceptable limits for therral expansion, vibration, and dynamic response in accordance with design parameters during l steady-state and transient conditions.* l8 34 14.2.12.3.17.2 Prerequisites ~ 18 A. Construction activities on the systers to be tested are complete. B. Terporary instrurentation is installed where required. 15 C. Baseline positions and alignrent are recorded. D. Preservice inspection of the snubbers identified in the Technical Specifications (Chapter 16, Section 3/4.7.9) has been completed 18 within 6 ronths of the start of the individual syster preoperational tests. 14.2.12.3.17.3 Test Method 34 A. Expansion will be sonitored during plant heatups, cooldowns, and 8 operation at various power levels. l 'L. B. Piping vicration will be ronitored during steady-state and transient operation. C. Deronstrate that the ynamic respo se during' transient o ra lon meets 15 design parareters. t //724df; 42*v 2 Lf)etmtACriCLa6 cv psr 77d6. 3.9-/9. D. On original syster liestup and cooldown, verify snubber operability by corparing actual and expected therral rovement at specified terperature intervals. Also verify by observation and/or ressure-rent that adequate swing clearance exists. 18 E. For systers that do not attain design operating terperature, verify by observation and/or calculation that the snubbers will accorrodate the predicted therral rovement.

- If additional restraints are installed as a result of the preoperational piping test, the NBC will be advised of the change.
In addition, any ( stress analysis required to verify the change will be raintained on 8 file for FRC review. 14.2-129 Amendment No. 34, (1/84) D ^
