A387RACT on May 21, 1991, the Nuclear Regulatory Commission (NRC) issued a revision to its standards for protection against ionizing radiation, 10 CFR Part 20.

Although the revised part (55.20.1001-20.2401) became effective on June 20, 1991, licensees may defer implementation of the revised rule until January 1,-1993, Licensees continue to be required to comply with the provisions of li 20.1-20.601-until the time they adopt-the provisions of il 20.1001-20.2401.

Therefore,-between June 20, 1991.and' January 1, 1993 both the provisions of $$ 20.1-20.601 and il 20.1001-20.2401 are.in effect.

This NUREG presents a comparative text of the provisions of the revised Part 20 (55 20.1001-20.2401) to the text of-li-20.1-20.601 for use by the NRC staff and NRC licensees.

ACKNO'dhCOGLKENTS The comparative text of the provisions of 55 20,1-20,601 with the provisions of 55 20.1001-20.2401 were prepared by SCIENTECH, Inc. under Contract No.

l INTRODUCTION The comparative text in this NUREG is organized to show the full text of each set of regulationn in a side-by side format for ease of comparison.

The text of $$ 70.1-20.601 is on the left-hand j

side and the text of $$ 20.1003,20.2401 is on the right-hand side of each page.

The sections ap9 ear in the table in numerical order according to il 20.1001-20.2401, with the il 20.1-20.601 sections shifted and moved so that they appear opposite the orresponding sections of il 20.1001-20.2401~.

An arrow above the

$$ 20.1-20.1-20.601 provirion indicatos that the corresponding I

provision in $$ 20.1001-20.2401 contains the same requirements as the $$ 20.1-20.601 provision.

Where there is no provision in either $$ 20.1-20.601 or il 20.1001-20.2401, this is indicated by "No corresponding provision" in tha appropriate column.

The table is arranged so that each provision appears in its entirety in a portion of the table.

Where a particular provisin1 requires more space tren that available on a single page and continues to the n6xt this is in.icated by a note at the bottom of the page.

As an additional identifying aid, the applicable section n er for the text for $$ 20.1001~20.2401 is indicated at the to,

' each page.

Footnotes appear in the table with the section ot iragraph which they amplify.

The presence of a footnote it..ndicated by " TOOTH 0TE" and "END TOOTHOTE" at its beginning and end, respectively.

Since il 20.1-20.603 does not appear in nunierical order in the table, an index to those sections is provided at the end of the document.

This index lists those sections in numerical order and indicates the page numbar whero each section appears in tho table.

Although ev9ry effort has been made to ensure that the text of both $$ 20.;-20.601 and $$ 20.1001-20.2401 are the same as the text in thn Code of Fodoral Regulations and the Federal Reaister, differences may exist between the wording as it appears in the table and in the Federal Reaistgr.

If there are any differences between the table in this NUREG and the actual regulation, the wording in the regulation should be used.

For this reesort, the DAC and sirborne efftuent limits are not etweys proportionet es was the cose in appendix B to il 20.1-20.601 The air concentration values listed in Table 2, Coluuri 1, were derived by one of two methods.

For. those redionuctities for which the stochastic timit is govgening, the occteetionet stocheatic treetation ALI was divided by 2.4X10, relating the irhetstiert All to the DAC, es explained above, and then divideo by a f actor of 300.

• The f actor of 300 includes the following components: e factor of 50 to relate the 5-rem ennuet occupationet dose timit to the 0.1-rem limit for awatsers of the public, a f actor of 3 to adjust for the dif ference in. exposure time ami tre irtetetton rate for a worter and that for meneers of the public; and e factor of 2 to adjust the occipetionet values (derived for oestts) so

)

that they are aceticable to other age groups.

For those radionuctides for which etiseersion (enternet dose) le limiting, the occteetionst DAC in Tebte 1, Columre 3,' was divided by 219.

The factor of 219 is composed of a f actor of 50, es described above, and a f actor of 4.38 relating occtestionet exposure for 2,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> per year to futt-time esposure (8,760 hours0.0088 days <br />0.211 hours <br />0.00126 weeks <br />2.8918e-4 months <br /> per yeer). sote ghet en additieret f actor of 2 for age considerations. is not worrented in the sdsmersion case.

The water concentrations esere deriw=d by taking the most restr/ctive occyzstionet stochestic cret ingestler All and dividing ty 7.3x10. The I

f actor of 7.3K10 (mt) includes the followirs etaponents: the factors of 109 (Centinued on sent Page)

Note 2 of this appendix provides grespings of.-edionuttides which are applicable to unknown pristures of rediervux t ides.

These groteings (incitafing occupationet inhalation ALis eruf DAts, sir and water ef f tuant concentretions and sewerage) reesire htrating that the oest limiting I

radionuclides in successive ctesses are absmt.

The limit for the unknown misture is definad eben the presence of the one of the listed radionuctides comot be definitely escludad es being present either from knowledge cf the radionuclide conyssition of the source or from actunt M esur M s.

Table 3 " Sewer Disposet" the monthty everoga concentrations for reteese to senitary sewers are egpticebte to the provisions in i 20.2003. The concentration vetues were derived by taking the most restrigtive occtpetienst stochest)c cret ingestion ALI and dividing by 7.3x10(at). the factor of 7.3x10 (et) is composed of a f actor of 7.3X10 (at), the emuet water inteke by

" Reference Men," and e factor of 19, such that the concentretions, if the sewage reteesed by the licensee were the only source of weter ingested by a referewe mean during a year, would result in o ceneritted ef fective i

dose equivalent of 0.5 rem.

Sarne as 8. above 10 bal4'LtMt Ni AH v' t401 t b i Aasta.cr ow wo.....i On May t,1991, the Nuclear Regulatory Commission (NRC) issued a revision to its standards for protection against iontimg radiation,10 CI R Part 20. Although th.' revised part (C) 20.1001-20.2401) became effective on June 20,1991, licensees may defer implementation of the revised rule until January 1,1993. IJcensees continue to be required 60 comply with the provisions of $9 20,1-20.601 until the time they adopt the provi-sions of $$ 20.1001-20.2401. 'lherefore, between June 20,1991 and January 1,1993 both the provisions of 9h '").1-20401 and 59 20.1001-20.2401 are in effect. This NUREO presents a comparative text of the provi-sions of the revised Part 20 ($$ 20.1001-20.2401) to the text of $$ 20.1-20.601 for use by the NRC staff and
