OCCUPATIONAL RADIATION EXPOSURES b AT LIGHT WATER COOLED POWER RESCTORS l 1969 - 1975 1 W 4 INTRODUCTION l-T This report contains a compilation of the occupational radiation } exposures at light water nuclear power reactors for the years 1969- "p 1975. It is an updating of the inforn.ation contained in WASH-13111 and NUREG-75/032,2 which provided data through 1974. Data from plants l that were in commercial operation for a full year for the first time l, e in 1975 have been added. We have also included the data submitted to the USNRC for all power reactors in accordance with the requirements of 10 CFR Part 20.407. O For the first time, this report contains data on overexposures at nuclear power plants for the years 1971-1975. c \\ l D 3 Murphy, T.D., A Compilation of Occupational Radiation Exposures frca Light Water Cooled Nuclear Power Plants 1969-1973 USAEC, WASH-1311, .c May 1974. 2 Murphy, T.D., Hinson, C.S., Occupational Radiation Exposures at Light Water Cooled Nuclear Pawer Reactors, 1969-1974, USNRC,NUREG-75/032, 6 June 1975. 1 k 1

The 1974 and 1975 data for all plants were obtained from two '.[ sources,1) reports submitted to the USNRC to meet the requirements of 10 CFR Part 20.407; and 2) annual, semiannusi or nonthly operating reports q sutcittted in accordance witn individual station Techn cal Specifications. i Approximately twenty five percent of the licensees sutcitted infomation in accordance with Regulatory Guide 1.16 Rev 4, Reporting of Operating / Infonnaticn - Appendix A Technical Specifications. These reports are j available in public documert rooms (pDR) located near each licensed plant [ or in the 11.5. Nuclear Regulatcry Comission's Public 00cument Room at 1717 11 Street, Washington, D.C. j i The teminology man-rem is a unit of collective dose and, as used in this report, is the accumulation of the occupational radiation exposures of all individuals at the plant site including utility station personnel, t other utility personnel brought in on 6 te:nporary basis, contractor personnel and visitors. For this report this accumulatien of exposure is detennined by either of the following methods: 5 l c 9 I

Approximately one h5lf of the licensees submitted the sumation of the actua,l_ exposures of all of the individuals at their site. 2. For the remaining licensees wt determined the accumulated exposures by sum;ng the product of the numbers of individuals in each annual exposura range specified in 10 CFR part 20.407 . - J. b(2) by the mid point exposure :p -ach range. ') ,i Its both cases the resulting accumulated exposure is expressed in man-rams. Where a comparison could be made, the two frethods yielded a number

l...

of man-rems whicS were within fif tcen percent of each other. I MA*!-REM PER RtArTOR PER YEAR ti i Appendix A presents the total annual man-rem received 3t cach LWR power statlan for each year 1969-1975. If there is rnore than one reactor at each k station, the data in Appendix A is the total for all units. The average '.i-exposure per reactor per year for all LWR's, also categorized by pressurized 'M water reactc. and boiling water reactor, is presented in Tables la, Ib, and Ic. For those statioris which isave multiple reactors, the total exposure l 1 for the station is arbitrarily divided by the number of reactors at the 1 station to get the average exposures for each reactor at that station. .} The frequency distribution for the exposures of the reactors at each i station for the years 1969-1975 is plotted in figure 1.
