Abstract

922,498. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Oct. 20, 1961 [Nov. 4, 1960], No. 38065/60. Class 39 (4). A nuclear reactor core comprises a plurality of rotary fuel elements each having eccentric multiplying and non-multiplying regions (i.e. regions having infinite multiplication factors greater than unity and less than unity respectively) and being mounted for rotation to afford control of the reactor by the interchange of the positions of the multiplying and non-multiplying regions in the core. By way of example, the core of a fast fission reactor has seven fuel elements in the form of six drums 12 to 17 encircling a seventh drum 11, each of the outer drums being rotatable about its longitudinal axis and comprising distinct semicircular sectors 18, 19. The sectors 18 include natural uranium fuel enriched in the fissile 235-isotope and act as the multiplying regions while the sectors 19 contain a predominance of fertile material, e.g. the 238-isotope in natural uranium which has been depleted in the fissile 235- isotope, and act as the non-multiplying regions. The central fuel drum 11 is stationary. A reflector structure 20, e.g. iron or graphite bricks, or, alternatively, a fertile material, fills the outer interstitial spaces between the drums while the inner interstitial spaces afford locations for the insertion of conventional control rods 21 or further fertile material.
