SUBJECT:
- Shearon Ifarris Nuclear Power Plant Unit 1 C..II. Bettis operators, Purchase Order NY-435205 on Ruskin-supplied HVAC dampers ITIM:
The following damper tag numbers are affected by this condition:
AR-D3-1 CB-D2SB-1 AV-D15SA-1 AV-D78SA-1 FL-D35SA-1-4 AV-D79SB-1
.FL-D36SB-1-4 FL-D9SB-1-4 FL-D37SA-1-4 FL-D11SA-1-4 l
FL-D38SB-1-4 FL-D12SB-1-4 AV-D82SA-1 FL-D21SA-1-4 AV-D83SB-1 FL-D22SD-1-4 AV-D86SA-1 FL-D5SB-1-4 AV-D87SB-1 FL-D8SA-1-4 AR-D4-1 FL-D4SA-1-4
.AV-D9SA-1 SUPPLIFD BY:
Ruskin Manufacturing Company
.NATLTE OF D EFICIENCY: -
The following condition was discovered as a result of some Bettis operators failing a vendor in-house opera-t ional; test:
According to Bettis, some of the internal seals (made of ' ethylene propylene) in the operators become swollen, apparently due to absorption of the internal 1ubricant (Mobil Crease'28). This swelling s
increases friction-within the operator.' This increased f riction iney result.in. increased operator actuation time beyond that required - for design' conditions.

- TO EXIST:
. Based on al. copy of a telex from Ruskin to Ebasco dated
-- c December 2,- 1983 (received;approximately December 5,
' 1983); which indicated 'a' 10CFR21' reportable' condition -
concerning Bettis actuators, the condition was: determined to be, potentially treportable on -December'20, ~1983.
- Also,
. site-generated NCR-63-103 on December: 28,'1983 and NCR-84-333 oniFebruary, 10, 1984.were : issued.

o On January 18, 1984, CP&L informed the NRC by Letter NPC-169 that we would require until February 20, 1984 to determine the reportability of this item.
On February 17, 1984, CP&L informed the NRC by Letter NRC-182 that we would require until March 23, 1984 to determine reportability.
On March 23, 1984, CP&L informed the NRC by Letter NBC-198 that we would require until May 23, 1984 to determine reportability.
On May 22, 1984, CP&L (Mr. K. V. Ilate') notified the NRC (Mr. D. Myers) that the December 21, 1983 potentially reportable item had been evaluated and found to be reportable per 10CFR21 and 10CFR50.55(e).
SCOPE OF PROBLEM:
The following safety-related HVAC systems / areas are affected:
A.
RAB Electrical Penetration Area B.
RAB RHR Heat Exchanger Area C.
RAB Mechanical Penetration Area D.
RAB H&V Penetration Area E.
RAB Charging Pump Area F.
RAB Valve Callery C.
RAB Pipe Tunnels and Charging Pump Areas Exh. System H.
FHB Normal Exhaust System I.
FHB Normal Supply System J.
FHB Ioading Area SAFETY IMPLICATION:
Should the dampers fail to operate within the required actuation time, areas may not properly isolate and airborne contaminants may not be controlled as intended.
' REASON DFFICIENCY IS REPORTABLE: Should the dampers fail to operate within the design time limit during anticipated accident conditions, the radio-logical releases may exceed the 10CFR100 guidelines.
CORRECTIVE E
ACTION:
_ Replace lubricant and seals in affected G. H. Bettis actuators on Ruskin dampers supplied to SHNPP.
G. H.
Bettis is making available repair kits that contain the recommended lubricant, Molykote 44, and replacement s eals.
b
.n_.
a ;.,.
4 PREVENTIVE
- MEASURES:
Future orders for nuclear-qualified actuators should be furnished with Molykote 44 lubricant and EP seals.
' FINAL REPORT: Ruskin Manufacturing Company has placed an ormar for repair kits to replace seals and lubricants for all affected dampers.
Repairs will be made as kits are
~
received with completion by December. 31, 1984. At that time, a-final report will be issued.
