Moderator temperature coefficient of reactivity

{
  "id": "MLC-T-NUC-000305",
  "term": "Moderator temperature coefficient of reactivity",
  "field": "Nuclear energy and radiation",
  "definition": "As the moderator (water) increases in temperature, it becomes less dense and slows down fewer neutrons, which results in a negative change of reactivity. This negative temperature coefficient acts to stabilize atomic power reactor operations.",
