Claims (5)

  1. 가압수형 원자로용 연료조립체는 조립체 길이방향으로 배열되며 조립체 횡단방향으로 간격을 가지며 고정된 평행연료봉의 집합체로 형성되어 냉각수의 순환 및 봉주위에 감속경수층을 형성하는, 상기 조립체에 있어서, 주로 핵분열 우라늄에서 농축된 우라늄 산화물을 포함하는 제1 그룹의 봉(2,10)으로 구성되어 중성자를 방출하며 중성자 반응을 유지하여 감속경수층이 중성자를 충분히 열영역내로 유입시키게 간격을 가지는 주변부(1,11)와, 주로 플라토늄 또는 핵분열 우라늄에서 감손되는 우라늄을 포함하는 제2 그룹의 봉(5,15)으로 구성되며 주변부(1,11)에서의 봉(2,10)이 격거리보다 약간 작은 이격거리를 가진 중앙부(4,14)를 구비하는 것을 특징으로 하는 가압수형 원자로용 연료조립체.
  2. 제1항의 연료조립체에 있어서, 중앙부(4,14)에서의 봉(5,15)이격거리는 고에너지 영역에서 생성되는 중성자를 위해 충분히 얇은 경수의 층으로 정의되는 것을 특징으로 하는 가압수형 원자로용 연료조립체.
  3. 제1항 또는 제2항중 어느 한항의 연료조립체에 있어서, 스펙트럼 이동봉을 수용할 수 있는 가이드관(3,12)을 주변부에서 구비하는 것을 특징으로 하는 가압수형 원자로용 연료조립체.
  4. 제1항, 2항 또는 제3항중 어느 한항의 연료조립체에 있어서, 조립체 중앙부(4,14)의 봉(5,15)은 길이방향의 측면 스페이셔(6)에 의해 각각 간격이 유지되는 것을 특징으로 하는 가압수형 원자로용 연료조립체.
  5. 제1항, 2항 또는 제3항중 어느 한항의 연료조립체에 있어서, 조립체 중앙부(4,14)의 봉(5,15)은 상기 봉외부표면에 나선형으로 감겨지는 와이어에 의해 각각 간격이 유지되는 것을 특징으로 하는 가압수형 원자로용 연료조립체.
