After replacceent of the cachet and prescuria nc the prkat y syt.te a, the conor.ud rasket was still leaking. In order to continu.e with lou power operation of the teactor, a new conorcal with a cap uns de.;igned and fabriccted to seal off the entire port, since the telefic.s thithles nre only rtquired for pwer physics teasureraents. The necessary design and f abricatf oi of a ccal vill be inado during thc zero power operation.
