DESIGN REPORT FOR NMSR PRESSURIZED WATER LOOP AT ORR

PDF Version Also Available for Download.

Description

A pressurized water loop constructed in the Oak Ridge Research Reactor for use in the Maritime Reactor Program is described. irradiation testing of pressure vessel materinl specimens and several sets of fuel pins for the NS Savannah'' Nuclear Merchant Ship Reactor, NMSR, was completed. Operating conditions for the fuel tests nominally were 500 deg F and 1750 psig. The loop has capability for operation at 650 deg F, 2500 psig, with a maximum water flow rate of 80 gpm, and heat removal in excess of 150 kw. Design features include convenient access for insertion and removal of test specimens, efficient ... continued below

Description

A pressurized water loop constructed in the Oak Ridge Research Reactor for use in the Maritime Reactor Program is described. irradiation testing of pressure vessel materinl specimens and several sets of fuel pins for the NS Savannah'' Nuclear Merchant Ship Reactor, NMSR, was completed. Operating conditions for the fuel tests nominally were 500 deg F and 1750 psig. The loop has capability for operation at 650 deg F, 2500 psig, with a maximum water flow rate of 80 gpm, and heat removal in excess of 150 kw. Design features include convenient access for insertion and removal of test specimens, efficient use of equipmert cubicle space, and reliable operation. The loop is entirely constructed of 300-series stainless steel. A bypass purification and sampling system affords continuous waterchemistry control, and provision was made for attachment of special equipment for chemistry studies. Fuel and material test specimens are irradiated in the space provided by two tubes, 1.5 in. ID by 24 in. long, in positions A-1 and A-2 of the ORR core. The maximum unperturbed thermalneutron flux is approximately 7.5 x 10/sup 13 neutrons/cm/sup 2/. sec and the peak gamma heat about 5 w/g with the ORR operating at 30 Mw. (auth)
