4; Dear Mr. Criers In accordmece with Appendix A, Beaver Valley Technical Specifications, Licensee Event Report LER 81-29/01P, Technical Specification 4.0.5, Inservice Inspection Program, is submitted. This occurrence use reported to the Beaver,,1; Valley Resident Inspector, Mr. D. A. Beelanas, at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on March 25, 1981..

• < l On March 22, 1981, the Duquesne Light Company Nuclear Services Quality Control (NSQC), while performing a review of the Inservice Inspection (IST)-

requirements for modifications recently completed on a 3/4" and 1" branch connection on the Reactor Coolant syntam and Saf ety In.jection System, respectivefy, uted a discrepancy between the Plant Modification Manual (PMN) and the Teebadant Specificacions. The hydrostatic cent requirements of the f90t referenced the 1977-edition through the 1978 summer addenda of ASME XI, while the Technical

$peciffemtions require hydrostatic testing be performed to the 1974 edition-shrovsh the 1975 summer addende of ASME XI.

WSQC requested tlwt BE.Co Engineerdag evaluate t.he noted discreponey.

Doguesna 1.ight Cocpany F.nstneering infermed the statio. that the appliestide of the PMM resulted in the following two dif ferences between the two editions the Code.

Li)g 1)

Branch connections l'* er less are exempted from hydroatatie testing....'.,

af ter repair or modification. These lines are not exempted from

.. Y hydrostatie testing under the edition of the code required by the.'gQ Technical Specifications.

..,. a A hydrostatic test time of ten (10) minu' ens for exposed stees was 2) penniesible under the Code subsection 1HA-5210 referenced in die Feat.

A test time of four (4) hours for all areas esposed or unexposed, is required under thw subssetion of the Code endorsed by the Technical.

Specifications.

i Item (1) was applied to the hydrostatie testing requirements of the two 7

l hranch connection modifications performed during the current pleet shutdown.

Item (2) was applied to the modif testions completed during the refueling and l

modifleation outage from December 1, 1979 through Nevenber 22, 1980.

The discrepamey resulted when the FMN was prepared and the requirements of The mee of the two appliesttoms is 10 CFR 50.55a(s)(4)(1) were misinterpreted. Item (1) was presented as code case IF-210 and s techniestly justified in thet:

Item (2) was incorporated in the 1975 winter addenda of the.1974 settion of ASE II; and subsequently in the 1977 edition of ASME 31. The 1977 edition through the 1978 Thors are as '_

potential safety effects resulting from the use of the two applicatimes.

Origbily, relief wem granted f rom subsection ZWA-5210 permeraph (a)-via the Reactor Coolant System Techniemi Specifiestion bases, which stated. "RepairsAc on components 2 inchee la diameter or man 13er receive a surface = =ination ud:

assures a similar standard of integrity" and "...a leak test will ensure 1eek '

tightness during normal operation".

The failure to obesin an exemption from Subsection TWA-5210 paragraph (a) and permission en invoke Code Case N-210 prior to applying their specific mee an the se=ver valley Fower station 151 program is a violation of Technical specification 4.05, Lisiting condition' for Dperation related to Inservice,,,,,_.
