The nuclear administrator must estimate the value of any debt which, by reason of its being subject to any contingency or for any other reason, does not have a certain value.

The nuclear administrator may revise any estimate previously made under paragraph (1), if the nuclear administrator thinks fit by reference to any change of circumstances or to information becoming available.

The nuclear administrator must inform the creditor as to the estimate under paragraph (1) and any revision of it under paragraph (2).

Where the value of a debt is estimated under this rule, the amount provable in the relevant licensee nuclear company administration in the case of that debt is that of the estimate for the time being.
