원자력발전소의 증기발생기는 여러 요인으로 인해 부식 또는 누설 등 전열관 손상이 야 기되며, 특히 증기발생기 2차측 이물질은 사전에 발견 및 조치가 쉽지 않으므로 접근이 어려운 곳을 간접육안검사 장비를 이용한 이물질 검사 및 제거를 통해 증기발생기에 영 향을 주지 않고 문제진단 및 해결을 함으로써 증기발생기 건전성 및 효율성 증대에 크게 기여하여 품질향상을 증가시킬수 있다. ㈜한빛파워 O&M 사업본부에서 수행한 월성원자력 2발전소 3,4호기, 고리원자력 2발전소 3,4호기 및 고리원자력 3발전소 신고리1,2호기의 증기발생기 2차측의 Tube Sheet 상부의 이물질 검사 및 제거(In-Bundle FOSAR)를 ㈜한빛파워에서 보유한 이물질 검사 제거 장비 NTIS/GIIS 및 육안검사 장비인 MVIQ(Video Image Scope)를 이용하여 전열관 표면 및 환형공간부, 중앙통로부, 튜브다발내부를 육안검사(In-Bundle FOSAR)를 수행하여 전열관의 건전성 및 증기발생기의 발전효율과 수명연장에 기여하였다. ㈜한빛파워 O&M 사업본부에서 수행한 고리원자력 3발전소 신고리1,2호기 이물질 검사 및 제거(In-Bundle FOSAR)작업시 다음과 같은 문제점 및 개선방안을 사전도출 하여 시행하였다. 증기발생기 Handhole작업으로 인한 과피폭은 모의 훈련 및 방호용품 착용철저로 개선하고, 이물질 검사 및 제거(In-Bundle FOSAR)작업시 Lance 끼임현상은 장비설계검토로 사전예방하였다, 또한 장비 Trouble 문제는 수행기간 장비제작사 상주 및 장비 필수예비품 확보로 조치하였으며 이물질 검사 및 제거 작업 공정지연을 사전예방하기 위해 반복적인 모의 훈련을 실시하고 다양한 제거 Tool 및 Guide를 확보하였다.

This paper aims to study the use of the reflexive pronoun in a picture noun. I examined important questions about the selection of an antecedent, the choice of an anaphor, the interpretation of the anaphor and the order of antecedents and anaphors. It suggests the following as the properties of English picuure noun refexives. A. If a sentence is said in the antecedent's viewpoint, a reflexiveis used but it is said in the speaker's one a pronoun is used. (ⅰ) a. John?? heard some strange gossip about himself??. b. John?? heard some strange gossip about him??. B. If the antecedent perceives the content of the picture noun phrase, a reflexive pronoun is obligatory. (ⅱ) a. John knows that there is a picture of himself in the morning paper. *b. John doesn't know that there is a picture of himself in themorning paper. C. If theantecedent(addressee) is the identifier of the content of the picture noun, we use a reflexive pronoun but the speaker is the one, we use a pronoun. if both can be the indentifiers, either anaphor can be used. (ⅲ) a. Mary is drawing a picture of you/*yourself. b. Mary drew that picture of you/yourself. D. If the antecedent is animate, backward reflexivization is possible, but whether it is animate or not, backward pronominalization is possible. (ⅳ) a. John's paintings of them make my cars/slaves look pretty. b. These paintings of themselves make my slves/*cars lood pretty. I conclude the reflexives of English picture nouns are controlled by the pragmatic meanings or roles of the antecedent rather than syntactic conditions.
