Pre-operational testing of TFTR systems

The Tokamak Fusion Test Reactor (TFTR) is composed of 21 major systems, all of which must function in order to meet project objectives. To assure adequate, timely and reliable function of these systems, a sequence of tests is planned for various levels of assembly. The test sequence is keyed to initial operational phases. Additional tests are planned for later operational phases leading to full power performance with deuterium and tritium. The overall test sequence is intended to expose design and fabrication problems as early as possible for corrective action to minimize impact on the schedule. Operational tests begin at low power levels and progress in steps to design levels while critical parameters are monitored. The sequence of tests required to meet the goals of initial TFTR operation is described. (author)
