A. INTRODUCTION
SCction 50.36. "TTechnical Specifications." of 10CFR Part 50, "Licensing ot Production and UtilizationiFacilities," requires that easch applicant for a licenseauthorizing operation of a nuclear power plant includein his applica tion proposed technical specifications.These technical specifications as approved by the AE-Care incorrporated into tire facility license and areconditions oif the license. The technical specifications fornuclear power plants include a section on reportingrequirements. In addition to the reporting requirementsnecessary for compliance with the technicalspecifications of the license, there are specific reportingrequirements included in Part 50 as well as in Parts 20.40. 70. and 73 of Title 10. For the convenience oflicensees, these specific reporting requirements areincluded in the reporting program described in thisguide. Each report discussed in this guide is eitherrequired by AEC regulations or is normally specified inlicensees' technical specifications. In some cases thisprogram may need to be supplemented or modifiedbecause of unique plant design features or other factors.The need for a supplemental or modified program willbe determined on an individual-case basis. The AdvisoryCommittee on Reactor S'feguards has heen consultedconcerning this guide and has concurred in theregulatory position.
B. DISCUSSION
The information provided in the reports discussedherein should be sufficient to permit an assessment bythe Commission of all safety-related activities during andfollowing the startup of the facility.In addition to those reports that relate to the safetyof operation of the plant, the information on nuclearmaterials safeguards that must be reported pursuant tothe ('omliission's regulations is also included. The AEI'Regulatory staff has ieviewed Ihe types sf inorloratislatneeded.

In the courseof reviewing past AOR's the AEC Regulatory staff hasfound a wide variance in the type and detail ofinformation reported. To assure that AOR's submittedare consistent both in format and in the principalinformation included, the format for abnormaloccurrence reports presented below should he usci andthe information requested should be submitted whenapplicable. If investigation is not complete by the timethe initial report is submitted, the licensee should soindicate and give estimated time when a supplementalreport will be submitted.STANDARD FORMAT FOR ABNORMAL OCCURRENCE REPORTSReport Number: .(1)Report Date: (2a)Occurrence Date: (2b)Facility: (3)Identification of OccUrrence:(4)Description of Occurrence: (6)Designation of Apparent Cause of Occurrence: (7)DesignManufactureInstallation/Construction-Operator-Procedure-Unusual Service Condition Including Environmental-Component Failure-Other (specify)Analysis of Occurrence: (8)Corrective Action: (9)Failure Data: (10)Conditions Prior to Occurrence: (5)-Steady-State Power-Hot Standby-Cold Shutdown-Refueling Shutdown-Routine Startup Operation-Routine Shutdown OperationLoad Changes During Routine Power Operation-Other (Specify)NOTES TO AOR STANDARD FORMATI.
