Dear Sir:
In accordance with the requiranents of Title 10, Chapter 10, Ccde of Federal Regulations, Part 21, Tr===-ica Delaval Inc., hereby notifies the Comission of a potential defect in a cm ponent of a DSR or DSRV Standby Diesel G eerator.
'Ihere exists a potential problem with the engine's intake and exhaust valve springs which could result in engine non-availability.
Tran-rica Delaval has supplied the DSR and DSRV engines with this pot e tial defect to the following sites:

Novsber 6,1985 Page 2 Director, Office of Inspection and Enforement U.S. Nuclear Regulatory Cr-hsicn We have recmtly experienced isolated failures of this spring in conmercial applications. In June of 1984, one spring failed in a 16 cylinder engine used for ship propulsion, and in October 1985 eleven springs failed in a second ship.
The elevm springs all failed within a short time following a Coast Guard required over-speed test. We have not determined the causal relationship between the two evmts.
Wille our investigation continues, preliminary indicaticms reveal inpurities on the wire coupled with draw unrks frcm the manufacturing process and subsequmt incocplete shot peming. Additionally, all springs failed after an ext m sive operating period (approximately 5,000 to 7,000 operating hours).
During our investigation we reccumer.d all users inspect their engines for broken springs and to identify the original manufacturer.
This identification is made by the color of stripe painted on the springs the Betts spring has a Wtite stripe.
Our investigation of this problem is proceeding on a high priority basis. To assist in this process we request all users report the results of their inspection within thirty (30) days of this notification.
We will keep the esian and engine users appraised r
of the progress of our investigation.
A copy of this letter will be sent to all of the sites referenced in paragraph 2 of this letter as indicated by the carbcn copy list.
Our evaluation of this potential problem was coupleted cx1 Novaber 4, 1985.
