TECHNICAL SPECIFICATIONS AND EQUIPMENT CONTROL GUIDELINES
16.1 TECHNICAL SPECIFICATIONS AND EQUIPMENT CONTROL GUIDELINES
The Technical Specifications (TSs) for Diablo Canyon Power Plant (DCPP) are contained in Appendix A of the Operating Licenses. The TS Bases provide the bases or reasons for these TSs other than those covering administrative controls. In accordance with 10 CFR 50.36, the TS Bases are not part of the TS, and are included by reference in this section of the UFSAR in accordance with 10 CFR 50.34 and 10 CFR 50.36.
Changes to the TS Bases are processed in accordance with TS 5.5.14, Technical Specifications (TS) Bases Control Program.
The Equipment Control Guidelines (ECGs) provide administrative controls and operability requirements for selected equipment that is not addressed by the TSs.
ECGs are developed when controls are required by regulatory commitments or when plant management determines that it is prudent to control equipment to maximize its availability. TSs that have been relocated to licensee controlled documents are generally transferred to ECGs.
Similar to TSs, ECGs provide operability requirements, action statements, and surveillance requirements. If the equipment cannot be returned to service as required by the ECG, administrative review, approval, and evaluation under the plant Quality Assurance Programs is required.
Table 16.1-1 lists those DCPP ECGs that have been implemented due to relocated TSs in accordance with the U.S. Nuclear Regulatory Commissions (NRCs) Final Policy Statement on TS Improvements and 10 CFR 50.36, which include four criteria to be used for identifying TS requirements that may be relocated to licensee controlled documents. Several license amendments (LAs) were issued by the NRC related to relocated TSs as noted in Table 16.1-1.
The preparation and revision process for ECGs requires evaluation under 10 CFR 50.59 or other applicable requirements. All ECGs and ECG revisions are approved by the Station Director.
