本報告は,高速増殖原型炉「もんじゅ」1次主循環ポンプ(モックアップ)の低速駆動装置に関するもので,通常および緊急時のモードで性能試験,作動試験を実施し,以下の結果を得た。主モータとポニーモータの引継ぎは円滑に行なわれる。減速機,クラッチは効率よく動力伝達をし,ポニーモータの回転数およびトルクの変動はほとんどない。ポニーモータによる主循環ポンプ起動において,異常現象はない。ポニーモータ駆動時の負荷電流は,定格の約6365%であった。異常雰囲気温度でも,ポニーモータ,減速ギヤ,クラッチの性能は通常温度の性能と同一で,差異は認められなかった。ポニーモータ駆動時におけるポニーモータ軸受部振動は,小さい。

This report describes the performance test of pony motor system mounted on the MONJU primary prototype pump. The test was conducted under various operation modes, and the following results were obtained: (1)The transition from the main motor to the pony motor was achieved very smoothly. (2)The transmission of the pony motor system worked well with its speed and torque kept constant. (3)start-up of a pump with a pony motor was accomplished very smoothly. (4)Apony motor current was about 6365% of it rated operation. (5)A characteristics of pony motor system in high temperature atomosphere remained as same as that in the room temperature. (6)The amplitude of pony motor bearing vibration during operation was a little.
