iD. Analysis of Limitorque's Qualification Method Type testing was performed on a model SMB-0. It is intended through this program to qualify the entire family of Limitorque Actuators - SMB, SB, SBD, and SMB/HB in .d1 unit sizes (SMB-000 to SMB-5) . . The following. summarizes the testing performed.
. _ . Thermal Aging: . . . . . . ...______.._.u...... . . . -

a r.-.,
The description of-thermal aging will be provided based on the " " '
following breakdown of the test sample assembly:
a) Motor --
b) Actuator c) Contact blocks, torque, and limit switches
.a) Motor: The stator. of the Reliance motor with class Ril insulation was heat aged at 180 C for 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> by Reliance Electric. Certification to this affect is contained in G.h Appendix C of Appendix B to B0058. Based on the regression O line for the insulating material contained-in Section 3.2.1.2 of B0058, the stated aging parameters equate to a motor temperature of 162 F for 40 years.
E j b) Actuator: The actuator was not thermally aged. A review s of the parts lists for the actuator (REF Limitorque E Bulletin 871) indicates non-metallic internal parts consist
$ (- of lubricants, seals and gaskets. Limitorque has stated that the seals and gaskets are used in the actuator to
, retain the grease in the gear box. Since th.e actuator is n 4- permitted to breath during a DBE, the seals and gaskets i do not have to completely seal the actuator; therefore, failure of seals and gaskets would not deter the actuator 3 from performing its safety function. It should also be C' noted that grease instead of oil is used to minimize the 8 impact of a seal failure.
E The qualification of the lubricant is insured by adhering to the recommend maintenance and inspection program and demonstrating the capability of the lubricant during the adverse conditions of radiation exposure and LOCA.
The deletion of the actuator from thermal aging is justified by the above discussion.
c) Contact Blocks Switch Materials: Contact blocks and switches were not thermally aged. Justification for this position ~is contained in Section 3.2.2 of Limitorque Report B0058. The 1

Additionally, the locat ion of E'u n a -N s e a l s in the pilot solenoid valve as s e rrb l y are such that the seals w il l not see the max imum co il t e rrp e r a t u r e due to the heat s ink created by the metal parts and the surroundings (See Tab F-3, page 2 & 4 of the qu al if ic at f or package).
