Title: INITIAL OPERATION AND TESTING OF THE ARMY PACKAGE POWER REACTOR APPR-1

Abstract

The startup and initial operation of the APPR-1 and the results of the test program on the reactor are described. The latter program began with testing of the vapor container for leaks, checking the integrity of the entire primary and secondary systems, and testing of individual components. Pre-nuclear testing of the primary system was performed. The system was operated at full temperature and pressure using dummy fuel elements in the core. The reactor was brought critical and was generating electrical power one week later. Numerous low and high power performance tests were performed and the reactor reached its full rated power at 10 megawatts of heat. The temperature coefficient of the reactor was measured as --2.3 x 10/sup -4// deg F and the pressure coefficient as 2 to 4 x 10/sup -6//psi at the operating conditions of 450 deg F and 1200 psi. Measurements were made to demonstrate that the reactor would be cooled by thermal convection in the event of loss of primary coolant flow. Data are presented om Xe buildup, shielding, and over-all plant heat balance, and the control of water purity in both the primary and secondary system is described. The APPR-1 has proven itself to bemore » a reliable nuclear power plant with remarkable stability and it has operated so as to meet all design requirements. (auth)« less
