Ultradense deuterium as a nuclear fuel in laser-ignited inertial confinement fusion appears to have many advantages. The density of ultradense deuterium D(-1) is as high as 140 kg cm-3 or 1029 cm-3. This means that D(-1) will be very useful as a target fuel, circumventing the complex and unstable laser compression stage. We show that the material is stable apart from the oscillation between two forms, and can exist for days in the laboratory environment. We also demonstrate that an amount of D(-1) corresponding to tens of kilojoules is produced in each experiment. This may be sufficient for break-even.

    The heat generated by irradiated nuclear fuel is one of the important considerations for its safe storage, transport and possible recycling. One method to calculate the decay heat of irradiated fuel is from an inventory code such as FISPIN or ORIGEN-S. These codes were part of a code comparison...
