Dear Hr. Denton:

i Attached is Revision 4 to the Zion Generating Station The

?, Inservice Inspection Program for the First Ten-Year Interval.

proposed revision provides relief from hydrostatic pressure testsin funder IWA-5244(a) 1 system, t

. The proposed alternative involves testing under theThis request i provisions of IWA-5244(c).rovisions of Technical Specification 4,3.4.C.3 and 10 CF

,with

!50.55.a.g the p(5)(111).

' Should you have any further questions regarding this matter, please contact this office.

Very truly yours, h

ATTACHMENT Revision 4'to Zion Generating Station Inservice Inspection Program for . the first ten-year interval.

Relle_f Request from IWA-5244(a)

Relief is requested from hydrostatic pressure tests in the buried piping sections of the service water systems on lines OSWOl3-48", DSWD14-48", OSW001-12", and OSWOCS-10". (Ncte that the buried section of line 05 WOO 8-10" actually lies between two 10 to 12 inch reducers and thus is 12" in diameter.)

Code Requirements IWA-5244(a)

The pressure retaining buried compo'nents within the class

111 boundary are subject to the hydrostatic test requirements of tIWA-5244(a) each inspection interval.

Alternative and Basis As an alternative, testing for evidence of leakage shall be POrformed on the buried portions listed ebove in accorosace with

'- IWA-5244(c),'1980 edition. This will involve verification that flow under nominal operating conditions is not. impaired.

The design of the test boundary valves precludes using a prossure decay test as required by IWA-5244(a). An attempt was made to ' verify' continuity of. flow through the buried section as described in IWA-5244(b). The use lof a flow meter was not possible due to the lack of the required straight pipe length in the actual piping configuration..

l_ -In addition to the required methods of IWA-5244, an acousti- ,

cal. emission-leak test was' considered, but the design configurations

,of the valves would produce questionable or inaccurate results.

This matter has received station on-site and off-site rGviews. Based on the above,'it has been determined that the'aubsti-tution of the testing method of IWA-5244(c) for the required method of .IWA-5244(a) will have no significant ef fect upon the probability for consequences of an accident'or upon the health and safety of.the lpublic.
