YANKEE CRITICAL EXPERIMENTS HAZARDS SUMMARY REPORT

Davison, P W; Hunter, D; Jedruch, J

The hazards associated with the operation of the third of the series of Yankee critical experiments in which the water-to-uranium metal ratio is 4: 1 are described. These experiments will be carried out in a core lattice which has more moderation than the 3: 1 lattice; the temperature and void coefficients of the core remain negative but are smaller in absolute value. The energy released during the Maximum Credible Accident considered is lower than that given for the comparable incident considered in YAEC-31, provided advantage is taken of a weighted value of Doppler coefficient. It is concluded that the experiments to be performed on this critical experiment reactor do not increase the hazsrds to the public in the surrounding area beyond those hazards evaluated in YAEC-31.
