- 10 CFR PART 21 REPORT -
THE GRINNELL CORPORATION DISCOVERED DEVIATIONS ON A DUKE POWER
PURCHASE ORDER FOR GRINNELL HYDRAULIC SHOCK AND SWAY SUPPRESSORS
(SNUBBERS).
THESE SNUBBERS HAD BEEN QUALIFIED TO ENVIRONMENTAL CONDITIONS
THAT VARY FROM THE ACCIDENT ENVIRONMENTAL CONDITIONS CONTAINED IN
DUKE POWER'S SPECIFICATIONS FOR THE MCGUIRE AND OCONEE PLANTS.
GRINNELL NOTIFIED DUKE POWER SO THAT THEY COULD PERFORM A SAFETY
EVALUATION. DUKE POWER NOTIFIED GRINNELL THAT THE SNUBBERS ARE
OPERABLE AS SHIPPED. THEY ARE CONTINUING FURTHER INVESTIGATION
OF THESE SNUBBERS.
***UPDATE BY GRINNELL CORPORATION TAKEN BY MACKINNON ON 11/19/96
@ 0950***
GRINNELL CORPORATION SENT THE FOLLOWING FACSIMILE UPDATING THE
ABOVE 10 CFR PART 21 REPORT:
"GRINNELL HAS REVIEWED ALL CUSTOMERS DESIGN SPECIFICATIONS FOR
ENVIRONMENTAL CONDITIONS RELATED TO HYDRAULIC SNUBBERS. WE FOUND
THAT, EXCEPT FOR THE ORIGINAL INCIDENT WITH DUKE POWER, THE
HYDRAULIC SNUBBERS SHIPPED BY GRINNELL MET THE CUSTOMER'S DESIGN
SPECIFICATIONS. THIS REVIEW COVERED THE PERIOD FROM YEAR 1986 TO
PRESENT."
"SINCE DUKE POWER HAS NOTIFIED GRINNELL THAT THE SNUBBERS
SUPPLIED 'ARE OPERABLE AS SHIPPED,' WE HAVE DETERMINED IT IS NOT
NECESSARY TO FILE A REPORT UNDER THE RULES OF 10 CFR PART 21."
THE NRC OPERATIONS CENTER SENT THIS UPDATE TO NRR (VERN HODGE).
