In Supplement No. 20 the NRC staff concluded that WBN Unit 1 met all applicable regulations and guidance as stated in the SER and supplements. Based on satisfactory findings from all applicable inspections, on February 7, 1996, the NRC issued a full-power operating license to WBN Unit 1 to authorize operation up to 100-percent power.

In this and future Supplements to the SER, the staff will document its evaluation of TVA's application for a license to operate WBN Unit 2.

This supplement provides information specific to the operating license review for WBN Unit 2 regarding the status of the items remaining for resolution, which were outstanding at the time that TVA deferred construction of Unit 2 and were not evaluated and resolved as part of the licensing of WBN Unit 1.
