I. Summary Greer supplied twenty-four valve actuators to Posi-Seal Inter-national for use on valves at Seabrook, Unit 2. Two of the actuators were tested by Stearns and Rogers prior to installa-tion at Seabrook. The actuators did not open and close the valves in the required time. The actuators were disassembled and the component parts reviewed. tn incompatibility between the ethylene propylene rubber (EPR) components and the lubricant was identified. The incompatibility caused the rubber components to swell, which increased the cycling time for opening and closing the valves.
The actuator components were cleaned and reassembled using Molykote 44 and new EPR components. The Molykote 44 is a Dow Corning lubricant compatible with EPR. The actuators were tested and performed in accordance with the original specifi-cation.
The remaining actuators are to be returned to Greer, disassembled, cleaned, and reassembled using Molykote 44 and new EPR components.
The units are then to be tested to assure compliance with the original specifications. This action is scheduled to be com-pleted by the end of March 1985.

I_I, . Problem Statement
-Greer Hydraulics supplied twenty-four valve actuators (See Appendix A),'in early 1983, to Posi Seal International, Inc. for installation by United Engineers and Constructors on various systems of Seabrook Unit 2. Two actuators were tested for cycling speed prior to installation, on November 9, 1984, by Stearns-Rogers Manufacturing, Inc. of Denver, Colorado. The actuators were specified to cycle (opened and closed) in 3 seconds. The cycling speed was 1.8 to 2.3 seconds to open and 19 to 28 seconds to close.- All actuators were successfully tested by Greer and Posi Seal prior to shipment to Posi Seal. ,
The two actuators were then distssembled and all components reviewed. All components appeared to be in working order, except the ethylene propylene rubber (EPR) components, which were swollen. It was speculated, after a review with Greer engineering personnel, that an incompatibility with the EPR com-ponents and the lubricant existed.
It was decided to repeat the actuator cycle testing on November 20, 1984. The testing was done after each actuator was cleaned and reassembled with new EPR components and Molykote 44, a Dow Corning lubricant compatible with EPR. (See Appendix C) . Both actuators were then cycled and determined to be cycling at~the specified rate for opening and closing.
Samples of the swollen EPR components and the original lubricant were returned to Greer'for analysis. The analysis was performed by Analytical Research Laboratories, Inc. (See Appendix B). The analysis confirmed the incompatibility between the EPR components and the lubricant. The grease' originally supplied in the actuators was a petroleum based product incompatible with EPR.
III. Corrective Action The remaining twenty-two actuators are to be returned to Greer for corrective action. The. actuators are to be disassembled, com-ponents cleaned, and inspected. The actuators are to be reassembled with new EPR components and Molykote 44. The units are then to be tested to assure compliance with the original purchase order specifications. The repair of the remaining twenty-two units is to be completed by the end of March 1985.
The twenty-four units supplied to Posi Seal International, Inc. are the only units supplied by Greer Hydraulics for use in a nuclear
. power generating facility. Future actuators requiring EPR components are to be lubricated with Molykote 44 to assure rubber compatibility.

The SN 3148-1-2 grease was only a petroleum grease whereas the SN 3146-1-1 grease also contained some silicone grease. Details of the analysis and the analytical procedures are given in the attached report.

APPENDIX C p Silicon Lubricant Recommendation The Dow Corning Molykote 44 silicon lubricant is recommended for use with ethylene propylene. The'Molykote does not react with the EPR and therefore the seal swelling that causes actuator slowing is eliminated.
Hydrocarbon based lubricants provide oil that is absorbed into the EPR. The penetration of the oil'into the EPR creates swelling
-that weakens the bond within the cured rubber. The reaction between EPR and hydrocarbon based lubricants is the result of a mutual attraction the materials have for each other because of their similar molecular structures.
Silicon lubricants, on the other hand, have a molecular structure based on silicon and oxygen and are much different from the carbon and hydrogen molecular chain configuration. The molecular, differ-ences between the silicon lubricant and the EPR result in no attraction between the two substances.
Actual' test results indicate that EPR and other synthetic elas-tomers shrink from 1 to 2 per cent when in contact with Molykote 44.
The shrinkage is not detrimental to the life of Greer valve actuators.

(418) 357 3247 Greer Hydraulics, Inc. Lab Log No. 124071 1 January 1985 Two sets of 0-rings and gaskets with small amounts of lubricant on them were submitted by Greer Hydraulics, Inc. for identifications. The sets were iden-tified as SN 3148-1-2 and SN 3146-1-1.
~
A portion of the grease from each of the two sets was scanned using infrared spectrometry to identify the grease types., The grease from SN 3148-1-2 is a petroleum grease cataining only aliphatic hydrocarbons. The grease from SN 3146-1-1 contains the petroleum grease but also contains some silicone grease, possibly as much as 5%.
From each set of 0-rings an'd gaskets, the following were selected for polymer identification; the smallest 0-ring, the small gasket, the largest 0-ring and the largest gasket. Portions of each of these samples were acetone extracted using method ASTM 0297 to remove any grease or plasticizer. The extracted polynier portion was then analyzed using pyrolysis infrared spectrometry. All 0-rings and gaskets were made of the same kind of polymer. The polymer is iden-tified as an ethylene / propylene copolymer. This type of polymer is known to be recommended for use with water, silicone oils and greases, dilute acids or alkalies, ketones, alcohols and automotive brake fluids (glycols). It is not recommended for use with petroleum oils or di-ester base lubricants. Since the greases are primarily petroleum greases, poorer performance of the seals
~
might be expected. The presence of some silicone grease in SN 3146-1-1 may give a slightly improved performance.
