The inhour equation was derived using the bare core approximation and few group diffusion theory. The method can be used for any reasonable number of groups. Simple analytical expressions for the prompt neutron lifetime are given for two, three, four, or more neutron groups. Different constants were used for the prompt fast and delayed neutron energy groups. The effective delayed neutron fraction is shown to be numerically equal to the delayed multiplication constant'' times the delayed neutron fraction. The expressions are suited to hand calculation for the interpietation of critical experiments or the analysis of reactor transients for safeguard studies. (auth)
