Appropriate location for fission chamber detector in Tehran Research Reactor

In this work, the fission chamber detector with 5 MW of power had tested in different locations of TehranResearch Reactor pool. If the detector was located at the distance of 1 meter from the eastern edge of the reactor and atthe height of about 1.4 meters from the floor, it were the best location for detector counting but due to the differentplacements and displacements in western part of the reactor, it was not possible unfortunately. The dead time for 3 MWof power had been 1.67% which was the best result in comparison with Monte Carlo Code.
