Review of neutronic design criteria

The neutronic design criteria for fusion reactors is reviewed. It was found that some values for criteria are poorly fixed. For example, the tritium breeding ratio has often been set unrealistically high with no provisions for adjusting values. It was also found that although energy production is the primary reason for a reactor's existence, little effort has been made to maximize it by blanket energy multiplication. Lastly, further optimization studies could result in thinner shields
