Items that this cost includes

In particular, please explain how the following costs have been treated:

  1. Uranium extraction and processing
  2. Uranium storage
  3. Uranium disposal
  4. Connection costs to national grid

Unclear how this treats uranium and associated costs.

Items that this cost excludes

Detail on the conditions under which this cost is valid

This is for an "Nth of a kind" 3rd generation PWR.

Explanations as to why this cost differs from others

Limitations of this cost estimate


Typical average output is calculated from the 100% gross efficiency, the central 86.3% availability, the central 90% load factor and the central 5% auxilary power (86.2%90%95% = 74%). Note that the source gives ranges for these numbers, which we should perhaps imprive the tool to accept.
