Title: EXPERIMENTAL ORGANIC COOLED REACTOR CONCEPTUAL DESIGN

Abstract

The conceptual design for an Experimental OnganicCooled Reactor which will provide a flexible facility for experimentation to speed the advancement of the organiccooled power reactor toward its goal of economic nuclearpower was prepared. Basically, this goal called for a facility capable of irradiating simuiltaneously a number of different types of fuel structures and moderators under environmental conditions approximating or exceeding those in organic power reactors. These requirements were satisfied by an organic-cooled and -moderated reactor designed for operation at 40 Mw at 500 deg F inlet temperature. This reactor, as designed, could also be operated at 20 Mw and 7O0 deg F or intermediate conditions to provide desired test environments for the program. Plate-type fuel elements with stainless steel cladding over a UO/sub 2/-stainless steel alloy will be used. The reactor will operate at a pressure of 150 psi and a flow rste of 25,000 gpm. The system is designed to operate at pressures up to 300 psig and temperatures as high as 850 deg F. The reactor tank, thermal shields and biological shielding are designed for power levels up to 220 Mw. The design incorporates provision for installation of several experimental loops up to 7.5 in. in diameter. Ofmore » these, two loops about 6.5 in. in diameter and three loops 2.5 in. in diameter are recommended as part of initial construction. The core lattice spacing is such that driver (stainless steel) elements can be replaced by largecross-section power reactor elements for experimental purposes. Fuel and coolant studies can also be carried out in larger scale by utilizing the entire core and coolant system. Removable gride and tank internals will permit core rearrangement for testing any core array not accommodated by the original grids. The estimated cost for the reactor constructed at the National Reactor Testing Station (excluding loops) is 310,000 and the operating costs, not including the experimental program, are 510,000 annually fur a staff of 59. The estimated cost of one 6.5-in. OD loop is 4,000, and the total cost of the five loops which constitutes the recommended initial installation of experimental facillties is 800,000. -The general needs of the organic program and the principal design features of the EOCR are discussed. The research program and design objectives are given in detail. The EOCR design, supporting information, and design details are presented. ( auth)« less
