Initial startup full power operation of PARR-2

The Pakistan Research Reactor-2 (PARR-2) is a tank-in-poll type research reactor designed at nominal thermal power of 27 Kw. Experiments were conducted at low and full power level to determine kinetic and control parameters. Transient behavior of the reactor was tested with step input of 2mk and ramp input of 4mk reactivities and inherently safe characteristics of the reactor were thus confirmed. The performance of startup channels, reactor instrumentation and safety equipment was satisfactory. Theoretical calculations are also done which can be verified with the experimental results.
