The neutron flux in the P1 irradiation position, located within the outer graphite reflector of the University of Missouri Research Reactor (MURR), was characterized through a combined experimental and computational approach. Activation data from cobalt, molybdenum, iron, and nickel flux wires were analyzed using the STAYSL-PNNL software suite to generate an adjusted neutron spectrum utilizing the SAND-II 640-group energy structure. This unfolded spectrum was compared against Monte Carlo simulations performed with MCNP6.3 using a detailed model of the MURR core and reflector region. Agreement between the measured and calculated reaction rates was found to be within the experimental uncertainty for most of the neutron energies and positions tested, indicating a strong consistency between the adjusted spectrum and the MCNP-predicted flux. The resulting adjusted flux spectrum provides a validated neutron flux characterization for the P1 position, supporting high-fidelity materials irradiation studies, neutron activation analysis, and future modeling efforts at MURR.
