NRC ADMINISTRATIVE LETTER 98-05: AVAILABILITY OF SUMMARIES IN ELECTRONIC FORMAT OF TECHNICAL REPORTS BY THE OFFICE FOR ANALYSIS AND EVALUATION OF OPERATIONAL DATA

Addressees

All holders of operating licenses for nuclear power reactors.

Purpose

The U.S. Nuclear Regulatory Commission (NRC) is issuing this administrative letter to inform addressees of the availability on the Internet of summaries of technical reports produced by the Office for Analysis and Evaluation of Operational Data (AEOD). This administrative letter does not transmit or imply any new or changed requirements or staff positions. No specific action or written response is required.

Background

AEOD has published more than 500 reports on a broad range of operational experience since 1980. Some of these reports have been published as NRC technical report designations (NUREGs), including the NUREG-1275 series of Operating Experience Feedback Reports. These reports have been broadly disseminated throughout the nuclear community and to the public. Most reports can be found in the NRC's Public Document Room and the local public document rooms. Most of the reports may be found in the Nuclear Documents System database.

Discussion

Abstracts of the AEOD operational experience reports are now available at the NRC Home Page on the World - Wide Web at http://www.nrc.gov/NRC/reactors.html#AEOD. Full-text versions of those reports issued since 1992 will soon also be available for downloading as either a WordPerfect zipped file or as a Portable Document Format file. Instructions for ordering hard copies of the full text of any report are provided on the web site.

To facilitate finding information provided in a report, the report may have been identified in multiple places within the following four topics, depending upon its scope: Pressurized-Water Reactor Systems, Boiling-Water Reactor Systems, Activity/Human Factor Deficiency, and Topics.

Each operational experience report is identified by either a NUREG number or an AEOD number. AEOD numbers consist of an alphanumeric sequence. The first character is a letter prefix that denotes the type of report. The remaining characters comprise the report number, which indicates the year of publication and the sequence number of the report. The types of reports, their designators, and the numbering conventions follow.

Case Studies. Case studies are designated by a C prefix and involve substantive, in-depth analyses of significant safety issues that are identified through the review of operating experience.

Special Studies. Special studies are designated by an S prefix and document accelerated investigations and suggest or recommend regulatory actions that are to be completed expeditiously.

Engineering Evaluations. Engineering evaluations are designated by an E prefix. They document assessments of significant operating events and suggest remedial actions, if appropriate.

Technical Reviews. Technical reviews are designated by a T prefix and document studies of little safety significance. These studies typically conclude that planned or scheduled corrective actions of the licensee or nuclear industry are adequate.

Report Number. For reports issued in the 1980s, the report number is a three-digit number. The first digit is the last digit of the year of publication (i.e., a "0" indicates 1980, and a "1" indicates 1981). The remaining two digits are the sequence number, which represents the sequential order of reports published in that year. For reports issued in the 1990s, the report number consists of four digits separated by a hyphen (xx-xx). The first two digits represent the last two digits of the year of publication (i.e., "90" indicates 1990, and "95" indicates 1995). The last two digits represent the sequential order of reports published in that year.

This administrative letter requires no specific action or written response. Any questions about this administrative letter should be directed to the contact listed below in the Office for Analysis and Evaluation of Operational Data.
