Can we use neutron absorbers? Here's what wikipedia [1] says about them: "The most important neutron absorber is B [boron] as B4C [boron carbide] in control rods, or boric acid as a coolant water additive in PWRs. Other important neutron absorbers that are used in nuclear reactors are xenon, cadmium, hafnium, gadolinium, cobalt, samarium, titanium, dysprosium, erbium, europium, molybdenum and ytterbium; all of which usually consist of mixtures of various isotopes—some of which are excellent neutron-absorbers." By the way, boron carbide [2] has an extraordinarily high melting point (2763 C), maybe this could be handy if one wants to convert the thermal energy of neutrons into electricity.
