An experimental comparison was made in a hollow fuel element in PLUTO of a number of possible fast-neutron flux monitors with the object of providing such a flux monitor for irradiations in very high flux materials-testing reactors. If 107 mb is adopted as the reference fast-neutron activation cross section of /sup 58/Ni, the fast-neutron activation cross sections for the reactions /sup 54/ Fe(n,p)/sup 54/Mn and Ti(n,p)/sup 46/Sc are found to be 73 and 8 mb respectively. It is concluded from this experiment that the /sup 54/Fe(n,p)/sup 54/Mn reaction using iron enriched to 95% /sup 54/Fe will be an adequate long-half-life fast- neutron flux monitor for irradiation in the high-flux facilities such as those likely to be used in, for example, BR-2.
