Which consequence results with an overabundance of deuterium in a moderator?

💡 Explanation

Excess deuterium raises the neutron absorption cross-section because deuterium absorbs more neutrons than protium. Therefore, neutron availability declines rather than increasing the fission potential or improving thermal capacity of the moderator.
