In addition to the above mentioned items, issues related to the presence of burnable poisons in HFIR
fuel plates need investigation. The requirements of burnable poison concentration and form (elemental
boron verses boron carbide or the use of alternative neutron absorbers) need to be studied so that
methods for burnable poison inclusion in fuel plates can be better addressed. The impact of burnable
poison inclusion on the overall fuel plate production process will also need to be evaluated.c600
