5 B. 7:eed for the Proposed Action There are about 20 licensed uranina fuel fabricat ion plant s.

It is estimated that these plants wil.1 process about 13'+0 net ric tons of uranium in 1976, and the processing of about 10 t f ries that arount is projected for the year 2000. Data report ed to t he NRC purt:uant j l

There are also varying degrees of utilization of the data reuulting from nuch surveys. h1t i l e none espects of each 1.UR fuel fabrica: !on progr; , and fr. cili Ly a re uni.que to that operation, there are any mpec ts L:ut are common to all eparations. The NMSS liccuse revien rs r ust u'ke a very detailed analy sis of the healt h ,hysics j program as one part of the evaluation of the application, of ten requiring co.siderable correspondence with the applicant. In spite of this time consuaing effort, uniform health physics program require- ,

ments a re not achieved. It is reasoned that the development of a fairly detailed guide on health physics surveys at uranium fuel fabrication plants would improve safety conditions at many plants by upgrading the progrars proposed by future appliennts, and by leading to in:provements and greater uniformity in existing licenced programs.

It is expected that the guide will also result in some (unq ua n t i fied) reduction in t he com.ai tment of ImSS resources.

NRC reneurces would be cord t ted to the development, review, and publication of the proposed guide. The priaary safety benefi.t

]

assoc.ated with the guide would be the degree to which it racets  !

the need for the preposed action E,et out in II.B. An additional i

benefit to N:ISS would be less necessity for negotiations and i

correspondence with applicants and those seeking 1icenne renewals; -l i.e., the subject could be more ef ficiently dealt with I.n the licensing process. I B. Other Government Very little benefit or cost would be expected to accrue to any  ;

other Federal Agency or State program. (States license only quantities l l

C. 1.'.o n a s There would be a greater degree of uni formity of health physics survey progra.ns, and uparuding of the surveys i.n nome plants. To

~n the extent that this is a,chieved, the protecrion of the health of i l

r. ..

the workers would be increased through ir" proved eva7 un tion o f, or decrease in, r< diation levels or concent rat tunt, of rt:d ioactive natorial in restricted areas. iny changes in the henith phycics program of l

t the licensee probably would be in t he direct ion of increased cost.

f It is antici; itM tha t the pot ential foc reduct ion in exposure of p'escanel could offset any increase in cost of t he health physics p rogr:r s .

The guide is not expected to invoice any chaages in the desi; n of future plants, or in any back-fit of operating pinuts.

Consideration of the caliber of current fuel fabrication plant health physica staffa does not indicate that the guide would be likely to result in higher costs to provide addit Ienal tra iniug or .

to upgrade the staffs by other means.
