10CFR21 Interim Report 21-96-004: ITT Barton                                          l Hydramotor Actuator Pump Assembly Failed to                                           !
Develop Hydraulic Pressure During Testing l

==Dear Sir:==
g,  ;
On Merch 6,1996, Illinois Power (IP) identified the failure of a pump assembly for an ITT Barton series NH95 hydramotor actuator as a condition potentially reportable under the provisions of 10CFR, Part 21. The pump was withdrawn from stores and installed during an overhaul of the actuator. The function of the pump is to develop the hydraulic pressure to operate the actuator. During testing of the hydramotor actuator following the overhaul, the pump failed to develop hydraulic pressure. IP suspects that the pump did not develop pressure because it may not be fitted / ported properly. The pump assembly has been returned to ITT Barton for inspection. The pump assembly is ITT Barton part number NS109761EQX07.
l IP has not completed the evaluation of this condition required under the provisions           ;
of 10CFR, Part 21 and cannot do so until the supplier completes the inspection to determine the reason for the failure of the pump to develop pressure.                                 ;
ITT Barton has informed IP that the inspection of the pump assembly is scheduled to be complete by December 31,1996. IP will evaluate the ITT Barton inspection results when received to determine the reportability of this issue under the provisions of 10CFR, 9607300354 960725 PDR    ADOCK 05000461 S                       PDR                              _
