This report is a part of effort and the reliability of PARR-1 instrumentation and control after renovation/upgradation and assessment of linear channel has been performed. Before renovation there was only one channel which is now replaced by two channels having the operation based on one out of two logic. In this assessment the technique of component count method (CCM) has been applied. The same technique has been used in the studies for other channels of renovated I and C system. The comparison one to one basis with the old system concludes that system unreliability has been decreased. (A.B.). 6 fig.
