U.S. R= lear Regulatory Ccxrission ,

At Gulf States Utilities River Send Site, a failed Cra isF2f: Oil Plug was recently discovered during routine raintenance. The failed Plug was 22 gauge raterial.

On 3/10/80 the Oil Plug raterial specification was cFr.ged fr xn 16 gauge to 22 gauge. On 6/22/82 s ez:sterial specifica:icn was changed back frec 22 gauge to 16 gauge.

This Oil Plug, *.ich seals drilled oil passages in de Cradshaft, is installed by Transarerica Delaval. Tne til Plug is rolled into the CraisF2f: using an e:cansien tool. Foi ycr= inic:ra ion, ..

atta6ed is a ske:6 shcuing the Oil Plug as it is installed in the Cran'< shaft.

" *" s Oil Plu on the arom: c:g fails,st.ich oil fics Engine availability ray be affected depending is lost.

The F.ngines ranufactured before 3/10/80 and after 6/23/82 should have 16 gauge Flugs triless for scoe reason they have been changed after

.@ shipment. Parag aph 2 indicates those 11 Sgine Serial N.:6ers st.ich ocr records shcra :ny have 22 gauge Plugs installed.

We recocznend da all Fngines be inspected to deced.e if any 22 gauge Plugs are installed. The 16 gauge Flug has a wall thickness of

.0595. The 22 gauge Flug has a wall thickness of .0299. This wall thic'< ness should be checked by reasure::nn:. <

w Transamerica Delaval recocrnends all 22 gauge Flugs be replaced with 16 gauge Flugs.

The 22 gauge Flug can be re eved and replaced in the Sgine widcu difficulty. _

A copy of 61s le::er will be sent to all the Sites in paragraph 2 of this letter as indicated by the cc's, m
