e when warranted). Since 1993, a majority of plants currently operating have elected to convert existing TS to improved technical specifications (ITS) based on the applicable STS. A plant may not have incorporated in the ITS some or all of the STS changes approved after submission of the ITS application. A plant with ITS also may deviate from the improved STS because in the ITS conversion it chose to retain an existing TS provision in place of the corresponding improved STS provision. In accordance with 10 CFR 50.36(c)(2)(iii), a licensee is not required to modify TS that are included in any license issued before August 18, 1995. For these licensees, adoption of ITS and subsequent STS changes is voluntary.

Copies of travelers for NRC-approved changes to the STS may be obtained from the NRC website at http://www.nrc.gov.

An applicant for an OL under 10 CFR Part 50 is required by 10 CFR 50.34(b)(6)(vi) to include in the final safety analysis report (FSAR) “proposed TS prepared in accordance with the requirements of 10 CFR 50.36.” The OL applicant should propose TS based on the current STS and any
