7㎿급 중속 4행정 원전 비상디젤발전기 저속기동 적용 이후 연소실 성능에 미치는 영향에 관한 연구 A Study on the Effect on Combustion Chamber Performance After the Slow Start Application of 7㎿ Medium Speed 4 Stroke Emergency Diesel Generator for NPP
pp.931-936
In the past, the U.S. NRC(Nuclear Regulatory Commission) strictly required testing of the EDG for NPP through Reg.Guide 1.108 Rev 1. However, these test requirements acted as a deterioration and wear factor for diesel engines, and are now applying Reg.Guide 1.9 Rev 3, which relaxed regulatory requirements and improved performance monitoring. After applying the new regulatory guidelines in this study, the EDG analyzed the performance of the combustion chamber. As a result, there were no signs of deterioration or decreased performance of the current EDG. This is due to slow start, short operation time, the use of high quality fuel oil and proper maintenance. On the other hand, if the performance is proven, it is judged that proper period extension of cylinder maintenance is possible.
