Why does the caesium 135 produced in nuclear reactors not react explosively with the water in the reactor like we see with caesium 133 and water?

  1. Cesium-135 reacts explosively with water. Which is why nuclear fuel pellets are typically encased in stainless steel or zirconium fuel rods. This keeps the radioactive waste from mixing with the water.

    As shown below, uranium oxide fuel pellets are contained in stainless steel tubes as a containment barrier.
