Description

수냉식 원자로의 코어내부구조(core internals)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 상부 코어구조로 설치한 연료 저장풀(fuel storage pool)의 절삭단면도,
제3도는 센터링핀(Centering pin)을 고정시킨 상부 코어 구조 그리드판(gid plate)의 부분영역 확대단면도.

Claims (6)

  1. 연료조립체단편(fuel assembly endpiece) (7,8)의 리세스내에 자유단(free ends)으로 돌출되는 다수의 센터링핀(centering pin) (10)을 지지한 저부코어구조(lower core structure) (3)와 상부코어구조(upper core structure) (4)를 가진 수냉식원자로의 코어내부구조(core internals) (2)에 있어서, 중심공(center core) (22) 는 원추형상으로 경사진 단상구멍(stepped bore) (23)으로써 그 연료조립체 (5)에서 떨어져 있는 그 단부에서 구성되고, 그 단상구멍(23)은 센터링핀(10)과 단상구멍과 동일한 피치(putch)로 그리고 동일한 방향으로 원추형성의 구성을 하는 그 센터링핀의 원주면에 대해서 축방향으로 대치시킬 수 있는 플러그(plug) (24)를 수용하며, 그 센터링핀은 이것을 수용할 수 있는 구멍(18)에서 헐거움(play)의 거의 없는 피팅접속(fitting connection)을 하고, 그 단상구멍(23)의 레벨에서 센터링핀의 원주면은 그루빙(grooving) (25)을 구성시켜, 그 그루빙(25)는 플러그(24)가 상태운동을 발생한 후에 그리드판9grid plate) (9)에 형성된 구멍(18)벽과 체결접촉(positure connection)을 하도록 구성함을 특징으로 하는 수냉식원자로의 코어내부 구조.
  2. 제1항에 있어서, 상기 센터링핀(10)을 피팅(fitting)할때에는 상기 중심구멍(22)을 통하여 상기 플러그(24)의 막힌구멍(blind bore)으로 하나의 태핏(tappet) (32) 이 형성되고, 상기 태핏의 충격력은 센터링핀(10)의 그루빙(25)과 구멍(18)벽의 그루빙사이의 경도 차이에 따라 선택하도록 구성함을 특징으로 하는 상기 수냉식원자로의 코어내부구조.
  3. 제1항 또는 제2항에 있어서, 상기 플러그(24)는 그 플러그(24)가 상태운동을 발생한 후 단상구멍(23)에 재질로 된 비드형성부(bead formation) (35)을 받아드리는 적어도 하나의 주변요흠(34)를 구성함을 특징으로 하는 상기 수냉식원자로의 코어내부구조.
  4. 제1항 내지 제3항중 어느 한항에 있어서, 상기 센터링핀(10)의 원주면은 그 그루빙(25)의 상하에 하나의 리세스(27, 29)를 구비함을 특징으로 하는 상기 냉식원자로의 코어 내부구조.
  5. 제1항 내지 제4항중 어느한항에 있어서, 상기 그리드판(9)와 대향하는 소울더(21)에 요흠(36)을 형성시켜 그 주어진 거리에 탄성요흠(37)을 설정시킴을 특징으로 하는 수냉식원자로의 코어내부구조.
  6. 제1항 내지 제5항중 어느 한 항에 있어서, 상기 센터링핀(10)은 하나의 셋백(set-back) (39)을 구비하며, 그 셋백은 체결접소(positure connection)을 하고 중간편(38)을 구비함을 특징으로 하는 상기 수냉식원자로의 코어내부구조.
