These technical specifications, as issued by the AEC, are incorporated into the facility license and are conditions                                    In September 1974 the Regulatory staff published of the license. Technical specifications are now included                              Revision 2 of Regulatory Guide 1.16. This revision re- as two appendices to the license: Appendix A technical                                flected results of a Regulatory staff review of operating specifications relate to health and safety, and Appendix                              intormation needed to permit assessment by the Com- B technical specifications relate to environmental im-                                mission of safety-related activities during the operating pact.' Each of these appendices includes a section on                                  phase of plant life. Significant differences in this guide reporting requirements.
