THE HALDEN BOILING HEAVY WATER REACTOR
The project, officiaily designated as HBWR, was undertaken in 1956 by the Norwegian Institutt for Atomenergi as builder and owner. Project HBWR was conceived as a nuclear power experiment for the studying of the physical and technological aspects of a heavy water moderated reactor under boiling conditions at a power level above 10 Mw thermal. The facility is located at the outskirts of the town of Halden in south-east Norway and on the grounds of one of the large wood processing companies. According to agreement, the company will utilize the steam as generated under experimental conditions. The reactor vessel and the heavy water circuit are designed for 230 deg C steam operation. Utility steam at 205 deg C is raised in the secondary light water circuit. About 16 tons of heavy water are contained in the primary circuit, and the initial fuel cbarge of 7 tons is distributed on a 130 mm hexagonal lattice in the shape of 1 in diameter rods of natural metallic fuel in finned aluminum cans, fltted in steam shrouds. This initial fuel charge will, for the criticality limitation reason, presumably restrict operations to about 115 deg C, while 150 deg C is set as the limit for safe operation with aluminum as canning material. Spiking is planned to bring the reactor up to this temperature. A second charge'' type fuel is required to bring the reactor up to full operating temperature of 230 deg C. (auth)
