SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NOS. 50-445 AND 50-446 DIESEL GENERATOR CONTROL AIR REGULATOR SDAR:
CP-87-31 (FINAL REPORT) l Gentlemen:
On July 6,1987, we verbally notified your Mr. H. S. Phillips of a potential deficiency involving the air pressure regulator on the IMO Delaval Diesel l
Generators which may contain manufacturing defects in the dripwell gasket
{
seating surfaces.
These defects could cause a loss of control air which in
]
turn could cause a loss of starting air pressure.
The 10 CFR Part 21 report submitted by IMO Delaval indicates the defective regulators are identifiable by the date of manufacture stamped on the bottom of the regulator.
It has been confirmed that none of the defective regulators (including four installed regulators and three spares) are in use at Comanche Peak Steam Electric Station.
4 As discussed above, no deficiency existed at Comanche Peak Steam Electric Station, therefore no report pursuant to 10CFR50.55(e) is required.
Very truly yours, k). h.( % w )1 1
