As a result of research from 1974 to 1976, two likely solutions to the problem of tellurium attack have been developed. The first involves the development of an alloy that is resistant to tellurium attack but still retains the other required properties. This development has proceeded sufficiently to show that a modified Hastelloy N containing about 1% niobium has good resistance to tellurium attack and adequate resistance to thermal-neutron embrittlement at temperatures up to 650°C. It was also found that alloys containing titanium, with or without niobium, exhibited superior neutron resistance but were not resistant to tellurium attack.
The second likely solution involves the chemistry of the fuel salt.
Recent experiments indicate that intergranular attack on Hastelloy N
is much less severe when the fuel-salt oxidation potential, as measured
by the ratio of U4+ to U3+, is less than 60, the possibility that the superior titanium-modified Hastelloy N could This discovery opens up be used for MSRs through careful control of the oxidation state of the Fuel salt.
