The LPTR is a tank-type thermal, heterogeneous research reactor facility at the Livermore site. The light water moderated and cooled reactor core will generate a peak flux in excess of 10/sup -3/ n/cm/sup 2/-sec at an operating power of 2 Mw. Access to the flux is provided by a variety of experimental facillties, including 6 horizontal beam tubes (the largest almost 13 in. in diameter), 2 thermal columns (one largely removable to provide a high fast flux within an associated cave-like lrradiation cell), and 2 pneumatic tubes. These, combined with a number of other irradiation ports, are istended to make the reactor a versatile, flexible research tool, available to all groups within the LRL research program. The LPTR design calls for a core containing roughly 4 kg of U/sup 235/ in fuel elements of the MTR type, arranged within a 5 by 7 element grid configuration which also provides space for beryllium reflectors. Aluminum is the primary structural material in the core, and in the closed circuit cooling system. A compact biological shield is achieved through use of magnetite concrete. The reactor core is cortrolled by 4 boron-carbide shim safety rods and a stainless steel regulating rod, with convertional console control instrumentation. Total containment is emphasized in the reactor housing- an all- steel, air-tight structure which is connected to adjacent labs and the control room by an air lock. (auth)
