in-plant* releases of r11dioactivity that require e. acu~tion of individual rooms was inconsistent with the general thrust of the rule to require reporting of s gnificant events. They noted that minor spills, sma11 gaseous waste releases,
  -. or the dfsturbance of contaminated particulate matter (e.g., dust) may all require the temporary evacuation of individual rooms until the airborne concen-trations decrease or until respiratory protection devices are utilized. T ey noted that these evens are fairly COfl1'Tlon and should not be reportable unless the required evacuation affects the entire facility or a major portion thereof.
In response to these co1T1Tients th wording of this criterion has been changed to signi icantly narrow the scope of the criterion to include only those events which significantly hamper the ability of site personnel to performs fety-related activities.
The NRC has also revised this reporting requirement to eliminate reference to building e acuat.on and instead rely on specific radiologica release rate criteria .
Plant O erating and Emergency Procedures Several come ters said that the reporting cri eria sho uld not a e refere ce to plant operating and emergency procedures because:
: a. '  It would take opera ors too long to decide whether a pla nt condition was co ered by the procedures,
: b. The procedures cover events that are not of concern to the          RC ,
and
: c. The procedures vary from plant to plant.

Reactor Scrams
                . Several commenters said reactor scrams, particularly those scrams below po er operation, should not require notification of the the NRC within                    ~f 1
          ~ hour.

Cit i ng 10 CFR 50.72 as Basis for Notification A few commi,~nters* objected to citing &sect;50.72 as a basis when making a telepho ne no t i ficati on .        e letters o comment quest ion ed t he pur pose , lega l effec t) and burden on the licensee.

The
* conmi~sion does not believe that it is a unnecessary burden for a licensee to kno        3nd identify the basis for a telephone notification required by &sect;50.72.      There have been many occasions when a licensee could not tell the NRC " hether the telephone notification was being made in accordance with vJ technical specifications, 10 CFR 50.72, some other requirement, orAjust a cou*r tesy can.      Unless the licensee can identify the nature of the report, it is  difficult for    t he. RC  to  know  what significance        the  licensee attache5 to the report and it b comes more difficult for the                  RC to respond quic ly and properly to th*~ event.
Persor1: :c4 Radioact *ve Contamin ation Several co enters objected to the use of ague terms such as "extensive onsite contamination" and "readily removed 11 in o e of the reporti g criterion of the proposed rule.
Based on this commen~ ne~ criteria have been prepared that do not use these terms.
Notification Ti ing The commenters ge era1 ly had two points to rn.ake regarding the timing of reports to the NRC.        first, the comments          upported notification of the RC after

Based on these commen ts and its experience, the NRC has established a 11 four-hour report 11 category titled "Non-Emergency Notification 11 as was suggested.
Im;.,::d
* a e S utdol'm Several co menters objected to the use of the term "immediate shutdown 11 saying that tec hn ical s ecificat*ons do not use such a term.
 
              ---                                Since the term *is used in some bu not all . Technical Specifications, the I
ColliTlission has revised the reporting *c riterion in question. The final rule requires a report upon the initiation of any nuclear po er plant shutdown required by Technical Specifications.
Explicit Threats                                                                        \
I A ff!W commenters said that the intent of the term "explicitly threatens 11      l was unclear .      Those commenting wondered what level of threat was being referred I
to. The t'erm 11 explicitly threaten" ha., been deleted from the final rule.
I I
Instead, the wording ofAfinal rule r;fers to "any event that threatened the safety of the nuc1ear powe r plant" (50 .72(b)(l}(vi 1 ) and gi~es examples so that it is clear the Co        issio is interested. in real or actual threats.
III. SPECIFIC FINDI GS Ove rvie of the Immediate otification Syste When this final rule becomes effec ive, the immediate notification reporting requiremen tI ill pro ide the RC with ti mely reports of e ergencies and other significant events.      This amendment of &sect;50.72, "Notification of Signifi-cant Events" will resul t ) in basicall~ three types of impr?vements.
One improvement is that the NC will receive not i f ication of safetY,~
significant events that were not previous l y covered under the existing provisions of &sect;50.72.        For exa ple , the final r4le requires reporting of any "major loss of emergency assessment or communications capa ility (e.g., significant portion of control room indicator or Emergency Notification System) .      11 This and o her changes in repor ing criteria will prov :de the NRC ith a more co plete Irrnnediate Notifi ca ion System.

of this pa agraph is to capture those evens where the p1ant, i eluding is principal safety barriers, was seriously degraded or in an unanalyzed condition.
For exampl e, sma ll voids in syste s designed to re o e eat fro t e reactor core which have been previously shown through analysis not to be safety significa          1 need not be reported.      Ho ever, the accumuloticn of vo*ds that could in ibit          e ab"li    y ta adequately remo e heat from the reac or core, particuler1y u der natural circulation conditions, would consti ute an unanalyzed condi ion and

an erroneous i dication causing the operator to misunderstand he true cond'tion of the plant is also an unanalyzed condition and should be reported.
The Commission recognizes that he licensee may us~ engineering judgment and experience to determine whether an unanalyzed condition existed.            It is no t intended that this paragraph apply to minor variations in indi idual parame ers, or to problems concerning single pieces of equipment.        For example, any time, o e or ore safety-re a ed co        onents ay e        of serv*ce due to es i o, mainte-ance, or a fa u t t ha has not yet been repaired.      Any trivial singl e failure or i nor er ror in    rfo  ing sur eil l ance tests could produce a sit uatio    in hie

Techni-cally, this is an unanalyzed condition.      However, these events should be reported only if they involve functionally related components or if t ey significantly compromise p1ant safety.
Finally, this paragraph also includes material {e .g., meta11urgical.

This paragraph is intended to capture t ose events where there ~s an actual threat tc the plant fro    an eternal condi*'on or natural phenomenon, and here the threa    or da age challenges t he ability oft e plant to co ti nue to operate in a safe manner (including the orderly shutdo'rln and a i ntenance of sh utd o *n conditions).

The intent and scope of      is reporting requirement have not cha ged fro            that 1n the prbposed rule.
This paragraph is in ended to capture events during which an ESF actuates, eit er manually or automa ically, or fails to ac uate .              It is ased on he premise that the ESFs are pro ided to mitigate the consequences of the eve t; there ore, (1) they s ou1d or prop r1y when called upo and (2) t ey s ou1d not be challenged un ecessarily.      The Commission is interested t)Ot in e e s where an &#xa3;SF as needed to      i igate the consequences of            he e et ( e her or

Paragrap 50.72(b)(2){iii) and (iv) (proposed 50.72(b)(4)] requires report.ing of:
        "Any e ent or condit,on tha alone could have prevented _he ful illment of the safety function of structures or syste          that are needed to:

ln respons e to pubic comments, the ords "any insta ce of perso al error, equip en failure, or discove        of design or procedural inadequacies" ta appeared int e prop:"lsed rule have been replaced by            e ords e et or cod. ion".
0 This simplification in language i~ *ntended to clarify what as a confusing phrase to many of those who co      en ed on the proposed rulE.        Also in response to  ub 1 i c co ent,    his report* g requi remen  is a  "f ' n-E erge cy to be 11 repo    ed with*n    our ours i stead of    i  hin one hour.

In surrmary, the ording of this .paragraph *has been changed to ma e it easier to understand,    hi1e the i~tent and scope of the paragraph ha e not been changed. *This paragraph is based on the assumption that safety-rela ed syste      5 and structures are intended to mit\gate the consequences of an accident. Wile          1 pa ragraph 50.72(b)(2)(ii) applies to actual dema ds for actuation of an ESF, paragraph 50.72( )(2) (ii ') co ers an event    ere a safety sys :e could have fai le.d to perform 'ts intended function because of one or mon1 perso e1 errors, including procedure io a *o s; equip ent failures; or design, ana ys s, fa ricatio , construction, or procedural deficie cies.        e events o ,d b

The app1ica ility o paragrap includes those safety s s es designed to mitigate the consequences of an accident (e.g., co tain e        so a o , e rge cy filtra *on }. Hence , inor operat*onal events sue as val e pac ing ea s, w ic could be considered a lac nf control of radioact* e material , shourd not be reported under this paragraph.

This paragrap does not include t ose cases where a syste or co onen i s remo ed from service as part of a planned e elution , in accorda nce with an approved procedure, and in accordance with the plant's Technical Specif'cations.
for exa p e, if the lice see remov es part o a syste fro ser ice to perfor maintenance, and the Tec hn ical Specifications permit the resulting co figurat*o,

... lubrication. Jnd e g*neeri    g  judgment ind'cates th t .here is a reasonable expectation that the funtt'onally redundant pump,            hich was also improp.~ly lubr*catea, would have also failed bE!fore it completed i s safe,ty unction, then the fa .ill.ire is reportable and the potential faiiure Jt the func . .onally redundant pump rnust be discussed in the LER.
Interaction between system. particularly a saf_ty syste . and a non-safety system, is also included in this c iterion.          Fore a~ple, the Co          is~ion s
    *ncreas*ng1y concerned about the effect of a 1oss or degr dation of what h' d been ass umed to be non-essen ial inputs~, safety syste s.            Therefore, this paragraph also includes those cases wh~re a service (e.g., heat i ng , ventilation, and . o1ing) or input (e.g., comp ressed air) which is necessar for re1iabJe or lon~-term opera ion of a safety system is lost or degraded,            Such loss or degradation is reportable " f      he prope r fu l fill men t oft *-~ safet function ls not or can not be assured.      Failures tha    affect inputs or services to systems hat ave no sa e y function need not be reported.
Finally the Commis_sion recognizes that the ~icensee may also u e engineering judgmen to decide when personnel actions coulQ_ have prevented fulfill ent of a safety fu ,c tion. For example, when an individual improperl        operates or maintains a component, he mi ght conceivably have made the same error for all of the functionally redundant component        (e.g .* if he *ncorrect y calibrates
    ~ne bistable amplifier in the heactcr Protection System, he could conceivably i correctly cali brate all bis ab ea plifiers).          Ho ever, for an e ent to be reportable *t is necessary that the actions actually aff~c            or involve components i    ore t han one train wr channel of a safety s s e , and the result of the

safety of        he public. The components can be functionally redundant (e.g._ t o pumps in d'fferent trains) or not functionally redundant (e.g., the opera or correctly stops a pump in Train "A" and, instead of shutting the pup dischargE val e in Train 11 A, 11 he mistakenly shuts the pump discharge va ve in Train B").      11 Paragraphs 50.72(b){2)(v) and (vi) [proposed 50.72(b)(6)) require reportir 11 (i)  A y airborne radioacti e release that exceeded 2 times the applicabl concentrat *ions of the limits specified in Appendix B, Table I of Part 20 of this chapter in unrestricted areas, whP.n a eraged over a time period of one ho (ii) Any liquid effluent release that exceeded 2 t*mes the 1i ti ti g co .

Immediate notifications must be made to the Corm1i*s sio i accorda ce with
                            &sect;S0.72(b)(2)(v).          These i  ediate notifications also meet the req uireme s of
                            &sect; 20 . 403( a ) ( 2 ) of Pa rt 20 of th i s ch apter . 11 These paragraphs have been chang d to clarify the requirf. ents to report releases of radioactive material. The first of these two paragraphs is similar o &sect;20.403 but p1aces a lower threshold for reporting events at corm1ercial powe i reactors.        The lowe r threshold is based on the significance of the brea down of the licensee's program necessary to have a release of this size, rather han on the significance of the impact of the actual release.
Based u on publ,c co ent, the report i ng threshold has been changed ~ro 11 25,4'" in the proposed rule to      11 2 times 11 in the f inal rule. Also, based on public co ent, this has been made as a 11 Non-Emergency" to be rt:ported wi thin 4-hours instead of within 1 hou . .

*.,. . :i. ~:
to make a more unifonn requirement by referring to specific release cri 11.eria instead of referring only to Technical Specifications.
This reporting requirement is intended to capture those events that constitute unplanned or uncontro 'l led releases of a significant amount of r,adioac-tive material to offsite areas.      Unplanned releases should occur infrequently ,
however ,      hen they occur, at least moderate defects have occurred in the safety design or operat ion al :ontrol established to avoid their occurrence and, therefore, such events should be reported.
Paragraph 50.72(b)(2)(vii) [proposed rJle 50.72(b)(7}) requires the reportir of:
              .        11
                          .Any event requiring transport of a radioact i vely contaminated person to an offsite medical facility for treatment."
Three chang'es have been made to this reporting requirement.                One is to e1 irninate the phrase "occurr*ng onsite ~' because it is implied by the scope of the rule.      The second change is to replace uinjury involving radiatfon 11              ith 11 radioactively co tam*nated person."      This c ange was made because of the difficulty in definfog injury due to radiation and more importantly *because 10 CFR Part 20 captures e ents involving radiatio n exposure.
The third change. in response to public comment, was to make this re orting require et a four-ho ur notification, instead of one-h ou r notifica ion .
Paragraph S0.72(b){2){viii) rnot in proposed rule] requires reporting of:
11 Any e et or situation related to    he health and safet of the public or 0 1 site    personnel or  ro ection of t he e vironrnent and for \-\'h ich a      ne\l.'S re ease is planned or not'fication to other government agencies -has been or will be made.

REGUL TORY A ALYSIS
(&sect;50.72)
OBJECTIVE The objective of the revised I ediate otification System described in 10 CFR 50.72, "!rmiediate Notification Requirements for Operating Nuc1ear Power Reactors" is to enhance the safety of nuclear plants by providing for timely notification to the NRC should sa ety significant events occur at operating nuclear reactors.
BACKGROU D The existing provisions of                  have generated basically three types of proble s. One problem is~certain safe y significa nt even          are not l,,J\,,c.
required to be reported. A second problem is that certain eventsAare i signifi-cant from the perspective of protecting the public health and safety are required to be reported. The third)and perhaps roost imp)rtan problej is tha existing reporting requirements are not coordinated;      For example. 10 CFR 50 . 3.
the new "Licensee Event Report" rule and the existing 10 CF 50 .72 do not use 1
similar terminology. phra:;ing or reporting thresholds.
1 In addition to the reporting problem noted ab ove, special consi deration must also be given to Section 201 of tne    ue:lear Regulatory Commission Authorizat*on Act for Fiscal Year 1980 (Pub . L. 96 -295). The in* ~nt of Congress as expres3ed
                                                                          )
in that laJ was that the Co ission establish specific guidelines for identifying accidents which could result in an unplanned release of ra dioact i ity in excess of allowable limits and to require immediate notification of these incidents.            ~ 7'fi :
re ision ofS&sect;S0.5 a d 50 . 72 is consis ent with ~ e intent of Co gress as A
expressed in the Authorization Act for Fiscal Year 1980.
The I RC published a proposed rule in the Federal Register on ece ber 21.
1981 (46  fR 81894} and su sequently received twenty letters of public com ent.
 
These 1 etters were generally supportive of the proposed revision of 10 CFR 'SO. 72 and these 1ett,e rs were most useful in the development of this final rule .
        -ALTER
            *- --- TIVES At the outset of this rulema ing, a wide variety of regulatory alternat ive s was considered . One al t ernative t hat was r ejected was the possibility of simply revising 10 CFR 50.72 without regard fr coordination with other rep orting requirements.      The need for coordination with o~her provisi'ons of 10 CFR, most notably the new LER system (10 CFR 50.73), resulted in the selection of t he approa ch defined in the final rule ,                      Each of the reporting criteria adopted in the final rule      as selected from a range of possible alternatives and each was co sidered carefully, usually by a corrrni                            ee representing the various elements Y- c. ~J; e. o of the    RC staff familiar            ith the rega~ informa .. ion and how the information could be collected from 1 icensees in the least burder som mann,e r through a part icular re po rting requir:e~ent .                      r        .

Consequently, a1terna ive 1 was selected.
BE EFITS AND COSTS The RC staff weighed the costs and benefits associat~d                          ith re ising 10 CFR 50.72.      The optimum benefi                is derived by revising both 10 CFR 50.72 and related portions of other reporting requirements.                            Accordingly, revision of 10
(\e.vJ CFR 50.72 is being coordinated ith develop ent of~10 CFR 50.73.                              In addition, a nu ber of substant{ve or administrati e cha ges are being developed that will amend other sections of 10 CFR Par~So,g-20,and Par 21.
The value of revising 10 CFR 50.72 goes beyond dollar be efits.                          The capability of the NRC to make timely decisions and to provide adequa e assurances .
regarding actual or potential threats to public health and safety depends on the rapidit with                  hich significant events occurring at nuclear cor.imunicated by nuclear power reactor lice sees to RC.
The majori ty*of events occurring tnroughout the nuclear industry pose little or no serious or immediate threatd-'to the public health and safety; however, certain events do pose such threats or generat~ fear or unusual concern.
