Abstract

In this paper, the result of an ultrasonic performance demonstration are analyzed. The requirements for an ultrasonic performance demonstration (PD) for a nuclear power plant were first described in ASME B&P Code Section XI, Appendix VIII (1989 winter addenda). In order to establish the performance demonstration scheme in Korean nuclear power plants, the Korea Hydro & Nuclear Power Co. Ltd (KHNP) has developed the Korean Performance Demonstration (KPD) system for the for the ultrasonic examination of nuclear power plants. An analysis of the ultrasonic performance demonstration results from 2004 through 2013 will improve the detection of flaws in an ultrasonic examination, as well as the further development of the KPD training system.

본 논문에서는 국내 원자력발전소 초음파검사자 기량검증시험 결과를 검토하였다. 원자력발전소 안전관련 설비에 대한 초음파검사 기량검증 요건은 ASME B&PV Code Section XI 1989 겨울 부록에서 최초로 언급되었다. 한국수력원자력(주)은 ASME Code Section XI, Appendix VIII의 요건 적용을 위해 국내 원자력발전소에 적합한 한국형 초음파검사 기량검증(KPD) 시스템을 개발, 규제기관의 승인을 받아 2004년 7월부터 운영하고 있다. 본 논문에서는 2004년부터 2013년까지 수행한 초음파검사자 기량검증시험 결과의 검토 내용으로 초음파검사 결함 검출 향상 및 기량훈련시스템 연구 개발에 도움을 줄 것으로 기대한다.
