The neutron decay constant, a, and effective delayed neutron fraction, beff, are important parameters for the control of the dynamic behavior of nuclear reactors. For the heavy water zero power reactor (HWZPR), this document describes the measurements of the neutron decay constant by noise analysis methods, including variance to mean (VTM) ratioand endogenous pulse source (EPS) methods. The measured a is successively used to determine the experimental value of the effective delayed neutron fraction as well. According to the experimental results, beff of the HWZPR reactor under study is equal to 7.84e-3. This value is finally used to validate the calculation of the effective delayed neutron fraction by the Monte Carlo methods that are discussed in the document. Using the Monte Carlo N-Particle (MCNP)-4C code, a beff value of 7.58e-3 was obtained for the reactor under study. Thus, the relative difference between the beff values determined experimentally and by Monte Carlo methods was estimated to be < 4%
