1、Designation: E1034 95 (Reapproved 2013)Standard Specification forNuclear Facility Transient Worker Records1This standard is issued under the fixed designation E1034; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThere is a high degree of concern in the nuclear industry regarding the ability of present recordskeeping practices to adeq

3、uately monitor the cumulative radiation doses of individual transientworkers. This concern arises from the fact that the transient worker moves rapidly among the nuclearfacilities, in some cases working at as many as four or more facilities within one calendar quarter. Theaccurate monitoring of a tr

4、ansient workers cumulative radiation dose depends, in part, on theindividual workers ability (and willingness) to provide a correct record of his occupational radiationexposure.At nuclear facilities licensed by the U.S. Nuclear Regulatory Commission (NRC), these datapresently are supplied by the wor

5、ker on forms NRC-4 and NRC-5. Similar procedures are followedat other nuclear facilities (see Note 1). Accurate occupational radiation exposure data are required toensure that the radiation doses that an individual transient worker will receive are within regulatorylimits.Another problem confronting

6、 the owners of nuclear facilities is how to in-process large numbers oftemporary workers efficiently. These workers may be required for such activities as the decontami-nation and decommissioning of a nuclear facility, the annual refueling of a nuclear power plant, or amajor special modification to

7、an operating nuclear facility. In-processing involves determining aworkers occupational radiation exposure history, security clearance, health status, ability to wear anduse respiratory protective equipment, and training and qualification for work in controlled areas.In-processing is the responsibil

8、ity of the licensee, and depends on the cooperation of the worker andthe workers present and past employers and other past contracting licensees.In-processing is complicated by the fact that different facilities keep the required information ondifferent forms in varying degrees of detail. In-process

9、ing one worker often can take several days andresult in a loss of productive time as well as increased staffing costs for the facility operator.One possible solution to these problems is a cooperative effort within the nuclear industry todevelop a common or central data base that can be accessed to

10、obtain pertinent historical data on aworker. A central record keeping system (CRS) is envisioned for this purpose. Such a system couldhelp reduce in-processing time for temporary workers.However, some degree of standardization is necessary before a centralized record keeping systemis possible. This

11、specification standardizes the necessary content of transient worker records.1. Scope1.1 This specification covers the required content and pro-vides retention requirements for records needed for in-processing of nuclear facility transient workers.1.2 This specification applies to records to be used
