The scope of these specifications is as set forth in Section 50.36 of 10 CFR 50 for Final Safety Analysis Report Technica l Specifications. Items in six broad categories are included:
(1) safety limits, (2) limiting safety system settings, (3) limiting conditions for operation, (4) surveillance requirements, (5) design features, and (6) administrative controls.
Safety limits are limits upon meas urable plant variables, such as thermal power, neutron flux, flow rates, pressures, and temperatures, which ensure fuel cla dding and reactor coolant system integrity.
Limiting safety system se ttings are settings for automatic pr otective devices that ensure that even under the most adverse situ ation anticipated, a safety limit will not be exceeded. Prime examples are the reactor trip settings. Instrument inaccuracies, calibration errors, and circuit response times, as well as calculat ional uncertainties, are considered.
Limiting conditions for operati on primarily establish the conditions of the various safety-related components and syst ems necessary to either begin r eactor operation or to continue operation. The reactor coolant sy stem, Chemical and Volume C ontrol System, steam and power conversion system, instrumentation systems, containment system, auxiliary electrical systems, and the systems making up the engineered safety features have minimum acceptable capabilities.
Specifications on pumps, valves, tanks, fluid levels, ch emical constituents in certain fluids, radioactivity levels, etc., ensure that the above syst ems meet their minimum acceptable performance levels.Surveillance requirements are imposed on pl ant conditions, system s, and components to ensure that the limiting conditi ons for operation are being met.
Tests, checks, calibrations, inspections, and samplings at ap propriate intervals verify the required plant conditions and performance capability of systems and components.
Design features include a descri ption of the plant' s site, reac tor containment, reactor core, reactor coolant system, and fuel storage facilities. The purpose of this section is to delineate the features of a plant not cove red in other specifications.
Revision 52-09/29/2016 NAPS UFSAR 16.1-2 Administrative controls are meant to preven t the existence or development of an unsafe condition in connec tion with the operation of the reactor.

VEPCO submitted proposed E nvironmental T echnical Spec ifications as Chapter 16A of the FSAR during September 1976. The NRC staff issued on November 16, 1976, a working edition of the ETS.
Revision 52-09/29/2016 NAPS UFSAR 16.1-3 The ETS underwent an iterative process of review and developmen t between VEPCO and the NRC. The finalized version of the ETS was issued by the NRC as Appendix B to the Operating License.
