World Bank, IAEA partner to fund nuclear energy
The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

An experimental comparison has been 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 Ni58, the fast-neutron activation cross sections for the reactions Fe54 (n,p) Mn54 and Ti46 (n,p) Sc46 are found to be 73 mb and 8 mb respectively. It is concluded from this experiment that the Fe54 (n,p) Mn54 reaction using iron enriched to 95% Fe54 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.
