A revision of the Monte-Carlo calculations in DP-Report--559 has been made and the ratio of the carbon-atom displacement rate per unit nickel fission flux in the Dragon capsule in Petten to that in the TE.10 hole in BEPO was found to be 0.49 as compared to the experimental value of 0.52. This result together with results reported in AERE-R-4701 for other reactor systems gives us confidence in using the Monte-Carlo method for obtaining the ratio of carbon-atom displacement rate per unit nickel fission flux from one reactor to another. Calculations have therefore been made using this method to relate the carbon-atom displacment rate per unit nickel fission flux in Dragon and a number of proposed HTR's with that in a DIDO Mk.III fuel element. These calculations were then used to give the DIDO nickel dose obtained in Dragon, and the proposed HTR's after a period of 300 days. It was found that the average DIDO nickel dose across a cell of a reactor was proportional to the power density for the reactor systems considered. (auth)
