Dear Mr. Sy._1via:

' ~ NRC' POSITION-ON IGSCC IN BWR AUSTENITIC STAINLESS STEEL PIPING t
SUBJECT:
GENERICLETTER(GL)88-01(TACNO.69135)
?
25, 1988,- the NRC issued GL 88-01. The GL requested iicensee's to lOnJanuary
..W respond within 180 days.of receipt of the letter regarding.IGSCC in austenitic r
. stair.less steel piping..By letter dated August 5, 1986, Detroit Edison Company
.(DECO)1 responded to GL 88-01. -By letter dated March 16, 1989, the NRC recuested
.f additional information.; Dy letters dated April 27 and May 12,1989,LDEco o
provided additicnal information.
E Enclosed is the-NRC staff Safety' Evaluation.
Based on the Safety Evaluation, 1the staff finds ~the Deco responses to GL EC-01 are complete'and acceptable with exception of the licensee's position concerning leakage limits.
- The. position concerning the tine from when a reactor is required to shutdown
-when unidentified reactor coolant leakage exceeds 2 gallons per minute changed-Lin' GL: 88-01 zfrort 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The Fermi-2 Technical Specifications (TS) currently' requires plant shutdown when unidentified reactor coolant leakage exceeds 2 gpm cver a 4-hour period which is a less conservative rate than the'-
limit' set in GL 88-01. The position of GL 88-011is to reduce the total reactor ccolant leakage. Therefore, we' request that DECO either propose a change to the'Formi-2 TS to be consistent with GL 88-01 concerning the leakage. limit or provide. justification for maintaining the current TS limitations given out.
' desire to reduce the total reactor coolant leakage.
