, EARLY CONTAINMENT OVERPRESSURE FAILURE At a meeting on Wednesday, November 12, 1986, with the NRC and their contractor Brookhaven National Laboratory (BNL), certain assumptions regarding early containment failure, referred to as NUREG-1150 assumptions, were discussed. For scenarios which involved high pressure accident sequences where the RWST is not injected prior to vessel breach, a median probability of early containment failure on the order of 0.01 was indicated under these NUREG-1150 assumptions . , As discussed in Section 4.2.4 of the RMEPS report (PLG-0432) and presented at the meeting on November 12, 1986, our assessment of these assumptions indicates that they are not physically possible under the
.. specific geometric configuration of the Seabrook plant. We would, therefore, interpret the results of any analyses resulting from these-assumptions as a sensitivity study to explore the safety margins and the robustness of the conclusions submitted in the RMEPS report.
s-In this context, we would like.to submit the following information for ' your consideration. According to Figure 11.3-14 (attached), the containment pressure at which there is a 1 percent probability of containment failure is 163 psia. The solid curve for " wet" containment conditions is used because at this time in the accident sequence the temperature of the concrete containment shell has not increased significantly from the normal operating temperature, and it is actually lower than the temperature upon which the solid curve in Figure 11.3-14 is based. Thus, this curve can even be considered conservative for this evaluation. ! The dashed curve in Figure 11.3-14 shows the contribution to the total
- failure probability distribution which arises from gross (Type C)
- - containment failures. At 163 psia, it is concluded that the conditional
( probability of a Type C failure, given that the containment does fail, is L 2 x 10-4/0.01 or 0.02. Thus, the conditional probability of a Type B failure at this pressure is 0.98. Note that the same conclusion would be reached even if an arbitrary 1% strain failure criteria is adopted, since , the pressure at which a 1% deformation strain occurs is 190 psia, well above the 163 psia pressure for a 1% failure probability. 1

An early type C containment failure on the other hand would be represented by release categdry S1 in . the SSPSA and in RMEPS and by 51W in the WASH-1400 sensitivity study. The characteristics of accident scenarios in which the NUREG-1150 assumptions were applied, namely, high RCS pressure and no-RWST injection before vessel breach, are both explicitly represented by the plant damage state parameters, as shown in Figure 11.4-1 in the SSPSA. Plant damage states with numeral designators 3 or 7 meet these conditions. A consistent set of point estimate frequencies for both the plant damage states and the release categories is given in Table 4-2 in the WASH-1400 sensitivity study (PLG-0465), as follows: Plant Damage States 30 and 70 3.8(-5) Plant Damage States 3FP and 7FP 1.9(-5) Total numeral 3 and 7 Plant Damage States 5.7(-5) Release Category S1 5.2(-9) - Release Category S6 3.2(-7) g Assuming a 1% early containment failure probability, as described above, for the plant damage states with numerals 3 and 7 would result in an increase for release categories Si and S6 as follows: Frequency Increase for S1 = 5.7(-5) - (0.01) - (0.02) = 1.1(-8)/ year Frequency, Increase for S6. = Sq(-5) - (0.01) - (0.98) = 5.6(-7)/ year The new total frequency of these two release categories for this t NUREG-1150 sensitivity case would become:
"NUREG-1150" Frequency. of S1 = 1.7(-8)/ year "NUREG-1150" Frequency of S6 = 8.8(-7)/ year Thus, if all the weight is given to these NUREG-1150 assur.ptionr., the frequency of release category S1 would increase by a factor of 3.2 and
- the frequen'cy of release category S6 would increase by a factor of 2.8.
The impact of this change on the population risk is estimated in the two attached risk suninary tables. Table 1 represents the WASH-1400 methodology case from NUREG-0465 with the Seabrook specific containment
- failure characteristics as assessed in the SSPSA. Table 2 represents the i WASH-1400 methodology case combined with the NUREG-1150 assumptions for containment failure. Table 2 thus combines both the assumptions of the WASH-1400 source term methodology, as well as the NUREG-1150 assumptions
+ for early containment failure. It represents a very' conservative combination of two fundamental assumptions addressing the sensitivity of
- the results.
O o I
t y'r - ' '* J $ovember 18, 1986 Page 3 of 6 The results show that the NUREG-1150 assumptions regarding containment failure do not have a large impact on risk. The early fatality risk for the no evacuation case increases by 15%, due to the NUREG-1150 assumptions, and the risk decreases a little more slowly with etacuation distance. With a two mile evacuation, the risk of early fatalities is reduced to 2% of the no evacuation risk, whereas, for the the WASH-1400 case (Table.1), the two mile evacuation risk is 1% of the no evacuation risk. Overall, we conclude that the NUREG-1150 assumptions for containment failure do not have a large impact on the results and conclusions presented in the WASH-1400 sensitivity study (PLG-0465), with regard to risk or safety goals. Because of the rapid decrease in the early fatality risk with evacuation distance, it is anticipated that the conclusions with regard to the 200 rem curve are also not affected. Therefore, we conclude that: (1) The NUREG-1150 assumptions with respect to early containment failure are not credible in the context of the Seabrook specific design and configuration.
~
(2) Postulating these assumptions in the sense of a sensitivity analysis would not have a large impact on the results presented in the WASH-1400 sensitivity study. (3) All of the conclusions with regard to emergency planning would ' still be valid. l S

RAI 47
Address the risk from creep failure of the steam generator (S/G) tubes due to exposure to high temperatures during core melt sequences
- in which the reactor coolant system (RCS) remains at high pressure and the secondary sides-of the S/Gs are dry. Your discussion should reflect-the recent experiments and modeling ef forts that show 3-dimensional convective flows which transfer heat from the overheating core to other places within the RCS, _particularly into the upper plenum and from the upper plenum along the hot legs into the S/Gs and through the U-tubes.
Also include the influence of pressure driven flows resulting from reactor coolant pump (RCP) seal-LOCAs, PORV/ safety valve actuations,
" bumping" the RCPs, etc. Localized heating ef fects due to redistribution of fission products in the RCS should be included. ; s. What is the total probability of occurrence for the high RCS pressure core melt sequence with dry S/Gs?
- b. What is the estimated conditional probability that the S/G tubes will fail due to overheating before the pressure is relieved by failure of the RCS elsewhere?
- c. What is the ef fect of preexisting S/G tube leakage (within technical-specifications) on .che heating rate and temperature required for failure of the leaking tube (s).
- d. What release category would creep failures of the S/G tubes result in?
RESPONSE 47 The risk from creep failure of steam generator (SG) tubes is very small for the following reasons:
. o The frequency of high pressure core melt with dry steam generators s is very small.
o Given the postulated occurance of a high pressure core melt
.' with dry steam generators, creep rupture of the SG tubes is not M a credible failure mode.
- I
,' o A large number of tubes must f ail to produce an early large containment bypass. -
A simple sequence diagram in Figure i shows that three failures must occur for containment bypass to occur as a result of a high pressure melt seq uence. The three failures are (1) failure to recover water to the SG, (2) f ailure to depressurize primary system and (3) creep f ailure '. of SG tubes. Success of any one of these three ensures success (no SG tube creep failure). O

' The potential for creep failure of the steam generator tubes for core melt
-dequences in which the steam generators are dry was evaluated using the
' best tools available including the MAAP 3.0 computer code developed in the IDCOR program. As a result of the technical issue resolution i I
process between IDCOR and the NRC, this code includes models for the ! natural circulation flows between an overheated core, the upper plenum, the hot legs and the steam generator tubes. The analytical updels used
' in the MAAP PWR program have been benchmarked with the recent published experiments carried out at Westinghouse under EPRI sponsorship. In addition, these analyses also include the influences of PORV/ safety valve actuations, as well as models for fission product release, transport ,
deposition and localized heating. Several variations of station blackout sequences were consicered: all assumed f ailure of main and emergency feedwater such that the secondary sides of the steam generators remained dry. The sequences studied include: (1) no RCP seal LOCA or manual PORV actuations (2) a 50 gpm per pump seal LOCA with no manual RCS depressurization (3) manual RCS depressurization when the core outlet temperature equals 12000F, and (4) several uncertainty analyses on key physical parameters in the system models. These analyses indicated that the steam generator tubes would not be subject to a sufficient temperature increase to result in creep rupture before failure of the reactor coolant system. In particular, since the secondary side temperature is limited to about 7000F due to L thermal inertia of the SG shell and heat losses to the containment , the SG tube temperatures only achieve temperatures of about-iiGG^2.~ This 700'I i is far less than that required for creep rupture. Based on information j provided in Appendix B of the attached draft report, creep, rupture of the SG tubes would not be expected. These conclusions are valid for all of the sequence variations considered as well as all of the uncertainties considered in the analysis which include variations in the core eutectic formation and slumping behavior, flows through the steam generator tubes, etc. l During station blackout sequences, the Seabrook operating procedures require ! that the operators monitor the f unctional restoration guidelines. These l guidelines would first lead the operator to consider restoration of l reactor coolant system inventory control which would be met with the , discovery that no electric power is available for this postulated sequence. Subsequently,,the restoration guidelines would lead the operator to consider procedures for restoration of a RCS heat sink. l The procedure for loss of heat sink calls for manual depressurization of the primary system using the PORVs. While this procedure is not specifically implemented for station blackouts and is only monitored, if new evidence subsequently turns up to support the view that creep rupture is a credible failure mode, the station blackout procedures 4 could be changed to require some appropriate method of RCS depressurization. The preferred method would be to blow down the secondary side of the steam generators using the SG PORVs. Such action would permit introduction of steam generator cooling via the firewster pumps (diesel driven). An alternative method would be to depressurize the primary system using the pressurizer PORVs. With such an action, the pressure difference imposed on the entire primary system pressure boundary is dramatically reduced, thereby eliminating any potential for creep rupture f ailures. I

The action of " bumping" the RCPs cannot be accomplished without the return of offsite power. If one postulates of f site power being returned, the
- operator would first' rest' ore ECCS systems. This action alone will recover ;L core cooling and make bumping the RCPs unnessary.
- In sunmaary, extensive NAAP 3.0 analyses, which includes models for the pro-cesses in question, were carried out in response to this question. These -
analyses show that the steam generator tubes would not be threatened by the creep rupture mechanism due to either the natural circulation flows between the core, upper plenum, hot legs and steam generators or the pressure driven flows resulting from RCP seal LOCAs or manual RCS depressurization. Also, the calculations show that localized heating ef fects due to fission I product deposition are not sufficient to increase the temperature of the steam generator tubes to a level where creep rupture would be 1 anticipated. Consequently, if any such mechanism were anticipated, it would occur elsewhere in the primary system long before the steam generator tubes would be threatened. The mean annual frequency of early high pressure core melt sequences of interest is approximately 4.5 x 10-5 events per reactor-year.

These sequences broadly include transient and loss of of fsite power sequences with failure of main and emergency feedwater and failure or inability to feed and bleed and transient without scram sequences. The above results for PDS 8A consist of 8 sequences involving station blackout and emergency feedwater f ailure in which ef forts to recover containment heat removal states are successful. In the containment i event tree analysis, all the "A" are assigned a high chance l of no containment f ailure, the "C" and "D" states a high chance of long term overpressurization, the "FP" states a high chance of small bypass
! and the "E" states a high chance of large bypass. Hence, in terms of relative consequences, the " A, C and D" states would experience the l'
greatest increase in consequences if a SG tube failure were assumed to result from creep failure during high pressure melt sequences. I

- ' These particular recovered sequences were assigned to PDS 8A. PDS 3F
' and 4y are not of interest because a large containment bypass (release category 56) already exists. PDS 3FP and 4FP are not of interest.
because a release path (S2) already exists. , , a l The above frequency of early high pressure core melt is conservative for three reasons. '
- 1. There are still potential recovery actions to ensure wet S/Gs not yet considered. For example, the dominant sequence (3D-1 on RMEPS page 3-58) involves a loss of sain feedwater transient and failure of the solid state protection system (mean annual frequency = 8.3 x 10-6). Solid state protection system f ailure is assumed to result in no auto initiation of safety equipment such as emergency feedwater. Emergency feedwater and other safety equipment can be started manually from the Control Room but these actions were conservatively neglected in the PSA.
- 2. There are early high pressure melt sequences with wet S/Gs in some of these plant states (i.e. emergency feedwater available and operating). For example, sequence 3D-4, a non-recovered station blackout and the operators don't depressurize S/Gs. Other such sequences include 4A-2 and 3, and 3A-29. (Exclusion of these sequences would not signif-icantly reduce the total estimated above).
y
- 3. No credit is taken for operator actions to manually depressurize which '
reduces pressure (i.e., riot high pressure core melt). Also, there is some chance the PORVs may fail to close. , 1 i The analyses indicate that the steam generator tube temperatures and the hot legs are both well below the levels where creep rupture would occur. In addition, it is likely that the operator would be instructed to manually depressurize the RCS when the core oa'elet temperature exceeded 12000F. This action would decrease the primary system pressure such that the stresses on the stesa generator tubes and the hot legs would both be reduced to levels less than that observed under normal operation. Consequently, the estimated conditional f requency that the plant conditions 1 for the hypothesized creep rupture of steam generator tubes would occur is dependent upon the likelihood that the operator would fail to manually ! depressurize the primary system. With modified procedures and adequate ' training, the frequency of operator failure to depressurize could be i reduced below 10-Z to 10-3 per demand. This would lower the frequency of creep failure potential conditions to the 10-7 to 10-8 range.
~
Given the occurrence of these conditions, the probability of creep rupture is a matter of our state of knowledge about the laws of physics that govern heat transfer to the SG tubes as opposed to a statement about. the relative frequency of a random process (which we make about the likelihood of achieving the necessary plant conditions in terms of l " frequency"). Due to cooling of the steam generator tubes by,the secondary side steam, the SG tube temperatures are well below (approximately l 700 Y ^0G4 6v r) that required for creep rupturet Due to the very strong dependence of creep rupture on temperature, 7 this consideration means ! that creep rupture would not occur even if high pressures are maintained. l _ i #%og )m,g ,, novcas o oc catre,q pcecte % Ca$c Cen@ red . m v _ r.- -e-.- n,,w.m._,.,~,m. -,e ,_ m.,_, _ _ _ _ _ ,.m.,.,m-

Despite the uncertainties in our models and data,'we are quite confident that errors as large as several hundred degress on the low side of the correct valve are not credible.3 To express our confidence in the models and data, we assign a 99% chance that failure of SG tubes will not occur before reactor vessel melt through or piping nozzle failure. The effect of a pre-existing steam generator tube leakage (within technical specification - 1 gpm per steam generator), would be a small flow rate compared to that created by the 50-gallon per minute flow assumed for the i pump seal I.0CA case. Since the major influence of an additional flow would be to provide higher temperatures in the steam generators, this is bracketed by the results of the pump seal LOCA case which showed no major influence on the steam generator tube temperatures. Given the assessment of the primary system response, potential for creep rupture of the steam generator tubes is extremely unlikely. Consequently, no specific calculations were carried out for the actual release categories since it is not risk significant. If specific questions were to arise regarding such releases, these would be analyzed with the MAAP 3.0 PWR code. If one postulates creep rupture failure of steam generator tubes, the pressure inside the previouly dried out and isolated stream generator secondary side
!- would increase until the steam generator PORVs setpoint is reached at I which time these valves would lif t and modulate until reator vessel melt 7
through occurs and the RCS depressurizes into the cone.ainment. There are no ' existing release categories / source terms analyzed for Seabrook or other PWR plants that adequately represent this scenario. During the periods of SG PORV opening, there would be a high leak rate bypass condition directly' from the RCS to outside the containment. However, after vessel melt 1 through, the leak rate out this path would be low corresponding to any low pressure leakage through the reclosed PORV. This leak path could be enhanced if the SG safety valves also lif t and f ail to reseat properly; however, it is believed unlikely that the safety valve setpoint would be reached. If a source term were developed for this scenario, it would i probably resemble S2 with the addition of an early puf f to cover the relief valve opened period of the release. Depending on the sequence, there may or may not be a long term overpressurization component to ,
- the source term.

SUBJECT:
SUMMARY
OF MEETING HEl.D ON NOVEM8ER 12, 1986 TO DISCUSS SEA 8 ROOK EMERGENCY Pl.ANNING SENSITIVITY STUDY
REFERENCE:
Seabrook Station Risk Management and Emergency Planning Study and Seabrook Station Emergency Planning Sensitivity Study. Submitted by letter from John DeVincentis to Vincent Noonan, dated July 21, 1986. A publicly noticed meeting was held on November 12, 1986, at NRC offices in Bethesda, Maryland. The NRC staff was represented by members of the Office of Nuclear Reactor Regulation, and Brookhaven National 1.aboratory. The Applicant was represented by members of the Public Service Company of New Hampshire, Pickard, l. owe and Garrick, Inc., Fau'ske & Associates and Westinghouse Electric Corporation. A list of attendees is included as Enclosure 1. .. The purpose of the meeting was to discuss issues affecting the level of confidence in PSNH's conclusions that could be established by Brookhaven's review of the referenced documents. The discussions' focused on the dose probability vs. distance parameterization of public risk. It was agreed that the region of interest lay in the distance range of a few miles and the probability range near the values shown by NUREG-0396 for a distance of 10 miles. (The PSNH results ghow the risk at 1 mile from Seabrook to be below the NUREG-0396 value at 10 miles.) BNI analyses are not yet complete enough to determine whether explicit differences identified in their review would challenge the PSNH conclusions, but those differences that have been quantified to date have not negated the PSNH conclusion. . There was also a discussion concerning confidence that all significant risk contributors have been identified and quantified. Because the Seabrook study resulted in reducing the overall risk by reducing the estimates for several
- known risk contributors, the question was raised as to whether other events that may have been neglected in previous studies because of low probabilities I might still have probabilities high enough to be significant contributors to j the Seabrook results. There was some confidence tentatively expressed by 1
Brookhaven personnel that all risk contributors significant to the region of interest delineated above had been identified. However, there may be some i difficulty in adeouately quantifying some of the potentially significant risk contributors.

~2-One potentially significant risk contributor not included in the referenced study is rupture of steam generator tubes during core melt due to convective transport of heat from the core to the steam generators. This was the sub.iect of an earlier meeting at Brookhaven on October 17, 1986. An additional presentation on this subject was made by Fauske & Associates personnel during the current meeting. Their conclusion was that the tubes would not reach temperatures high enough to cause creep failure. Copies of the slides from this presentation are included as enclosure 2.
2 The final topic of the meeting was a presentction by Westinghouse personnel concerning the potential for direct containment atmosphere heating by high pressure ejection of core debris at the time of vessel failure. Physical modeling results were presented for the Zion plant configuration to demonstrate that the fraction of the ejected debris that was aerosdlized ranged from 0.003 to 0.052. The slides from this presentation are included as Enclosure 3.

SUMMARY
OF MEETING AND SIMUI.ATOR TOUR HELD ON OCTOBER 15, 1986 TO FACILITATE NRC REVIEW OF THE SEABROOK EMERGENCY PLANNING SENSITIVITY STUDY
REFERENCE:
Seabrook Station Risk Management and Emergency Planning Study and Seabrook Station Emergency Planning Sensitivity Study. Submitted by letter from John DeVineentis to Vincent Noonan, dated July 21, 1986. A publicly noticed meeting was held on October 15, 1986, at the Seabrook Station in New Hampshire. The NRC staff was represented by members of the Office of Nuclear Reactor Regulation and Brookhaven National I.aboratory. The Applicant was represented by members of the Public Service Company of New
. Hampshire and Pickard, lowe and Garrick, Inc.
A list of attendees is included as Enclosure 1. , j The purpose of this visit was to allow the NRC staff and its consultants to examine the control room operating environment and procedures to facilitate its ongoing review of the referenced doments. .-
- During the morning the Seabrook simulator training staff presented and 1
discussed a new training module designed to assist the Seabrook operating staff in recognizing the occurrence of a loss of coolant accident (1.0CA) through an interfacing system, with emphasic on the RHR system. During the afternoon, the NRC personnel and consultants visited the simulator to visually examine the in,dications and controls available to the reactor operators. Procedures pertinent to emergency conditions were also examined. During the visit, simulations of two types of I.0CA sequences were run without operator intervention to demonstrate timing of events and some indications of 1.0CAs outside containment. (The Seabrook simulator is not now programmed to simulate event V.) One of the sequences was rerun to demonstrate operator recovery actions. The meeting was concluded following discussions of check valve testing procedures and indications for leaking valves, s / 4

SUMMARY
OF MEETINGS HEl.D ON OCTOBER 16 and 17,1986 1 TO DISCUSS SEA 8 ROOK ENERGENCY Pl.ANNING SENSITIVITY STUDY
REFERENCE:
Seabrook. Station Risk Management and Emeraency Planninc.Studv and Seabrook Station Emergency Planning Sensitivity Study. Submitted by letter from John DeVincentis to Vincent Noonar, dated July 21, 1986. Publicly noticed meetings were held on October 16-17, 1986, at Brookhaven , National 1.aboratory in New York. The NRC staff was represented by members of the Division of PWR I.icensing-A and Brookhaven National I.aboratory (9NI.). The Appl.icant was represerited by members of the Public Service Company of New Hampshire, Pickard,l. owe and Garrick, Inc., Structural Mechanics Associates, Fauske & Associates, and Westinghouse Electric Corporation. ' The purpose of these meetings was to facilitate the NRC's oncoing review of , the information in the referenced documents. There were two distinct sub.1ects covered by two separate working groups. A group which focused on details of containment strength calculations met b'oth days. A second group met only on October 17 to discuss convective transport of heat from the melting core to other parts of the reactor coolant system (RCS)." 1.ists of attendees are ! included as Enclosures I and 2. The group dealing with containment strenoth issues discussed in detail the containment strength calculation report prepared by Structural Mechanics Associates (SMA) for Pickard, l. owe and Garrick, Inc. (Pl.G). The SMA report was incorporated into the probablistic safety analysis study performed by Pl.G . The entire meeting was devoted to the discussion of the SMA report by Sle.] 2 % Y.l.(.pl
%pp.
3 L' ( (i-examining the methods used, the underlying assumptions regarding the variability estimates and results obtained. A number of items of clarification needed by the BNI. staff were discussed, and these action items were later forwarded to the I.fcensee in a letter from Steven M. l.ong to Robert J. Harrison dated October 23, 1986. The group dealing with convective transport of high temperatures inside the RCS during core melt heard presentations by Westinghouse and Fauske personnel. Physical model exoeriments at Westinghouse facilities in Pittsburgh were described, and computer modeling'of the convective flow phen'omena for hioh pressure core melt sequences at Seabrook was presented. The applicant concluded that the heat transport phenomena would not raise the steam generator tubes to a temperature sufficiently high to cause creep failure. An important element of the applicant's model is the interruotion and the convective transport mechanisms by the disruption of core oeometry dur,ing
. melt. Discussions focused on the nature of the mode'l and the sensitivity of its results to its underlying assumotions. Materials from the a*oplicants' presentation are included as Enclosure 3. ,
Questions arising in both meetings were formally submitted to tile applicant by letter dated October 23, 1986, from Steven M. l.ong to Robert J. Harrison. During a combined meeting of.the working groups at the end of the second dav, it was decided to publicly announce three additional meeting dates so that [ additional discussions could be held, if necessary, durino the period when the NRC's review is nearing completion. The dates chosen were November 6, 12 and 19, 1986.

e During unmitigated station blackout sequences, the presence of high pressures and no makeup lead. to strong natural circulation flows between the core and the upper plenum of the reactor vessel, e Since a loop seal exists in the pump bowls so that no flow can pass there, high temperatures in the upper plenum will initiate counter-current natural circulation between the steam generator inlet plena . and th'e RV upper plenum, e The resulting increased temperature in an. Inlet plenum leads to natural flows out to the outlet 7, c ,, plenum through some tubes and a return flow to the !.__ inlet plenum through other tubes.
, o High temperatures in the inlet plenum or tubes raise concerns 'that steam generator tube failures O could result.

SUMMARY
OF RESULTS
- 1. In the bcse case, peak stecm generator temperatures prior to vessel failure occur in the inlet plenum and are s 850*K, l
- 2. Seal LOCA case very similar to base case,
- 3. When the operator opens the pressurizer PORVs, -
depressurization occurs very rapidly due to the . small water inventory. Accumulator discharge
._ occurs approximately 1400 seconds later, Stecni generator temperatures. are low (4 700 *'K) prior to '
. depressurization below 7 MPa, Temperatures in-crease after complete depressurization but remain L generally lower than'the base case, -
6 . ' T, c. Steam generator
~
- 4. temperatures in the uncertainty
._ _ cases are significantly higher only in the low steam generator flow case where peak temperatures
. cre approximately 150*K higher. -

, Washington, D.C. 20515 ATTN: Lando Zech, Chaiman .
Dear Mr. Zech:
I am writing to ask that the Nuclear Regulatory Commission carries out
~
a comprehensive, independent investigation into ' alleged safety violations at the Seabrook nuclear power plant before it considers granting the utility a low-power testing license. Fomer employees at the plant have recently come forward and testified. to a long list of alarming conditions and procedures at the construction i site. These include epidemic levels of drug and alcohol abuse on the job, l electrical cables along the inside of containment vessel walls that give l off sparks and ignite small fires, a clogged and inadequate fire protection system, improper mixtures used in the containment cement, empty beer cans and bottles dropped into wet containment cement (which may create air pockets), improper training procedures for various jobs, including delicate welding work, and much more. By now everyone is aware that
- accidents can and will happen at nuclear power plants. At any moment during operation a cooling system, a fire pro-taction system, or a containment building could be tested to its limits, and the health and lives of thousands of people would depend on the integrity of the original design and construction of the plant. -
i Please know that we citizens are aware of the allegations being made p by Seabrook construction workers, and that they will not be satisfied with L the Comission undertaking anything less than a well-designed, well-monitored, L and independent investigation of these claims. [ Thank you for giving your attention to this matter. L Sincerely, b' Sally A.

g c. 2 Staff -on December 22, 1986, in response to Applicants' petition. - proposed that parties be allowed to submit schedules for responses to the petition by January 20, 1987 and that the Board schedule a pre-hearing conference during the week of January 26, 1987, "to discuss and schedule for further proceedings on Applicants' petit. ion." On January 5,1987 NRC Staff's Motion for Reconsideration of Licensing Board Order of December 23, 1986 was filed in which the Staff states its
" technical input will be of crucial importance to a proper detennination by the Licensing Board and by the Commission of the'important issues raised by the Petition." The Staff seeks reconsideration of the December 23, 1986 Order by requesting that a proposed schedule for reply to Applicants' petition be established and that January 20, 1987 be the due date for such schedules.
The Board finds that the authority vested by the provisions of 10 CFR 2.758 is to review the petition and any responses to determine if l the petitioning party has made a prima facie showing that the ,; application of the specific Conmission rule or regulation would not a
- - serve the purposes for which the rule or regulation was adopted and that
, the rule or regulation should be waived or an exception granted. This Board is not directed to conduct an evidentiary proceeding or to decide if a waiver or exception should be granted; this power is reserved to the Commission. Our duty and obligation is to review the petition and
Q. ( .y . 3 any responses and determine if a prima facie showing has been made by the petitioner. The Board affinns that responses will be filed in-hand by close of business on January 27, 1987. We have directed that responses address the Applicants' petition on the issue of whether a prima facie showing for a waiver of the 10-mile EPZ has been made. The Board expects all parties to diligently work to complete their responses by January 27, 1987. If, however, any party cannot complete its response by Janu-ary 27, then that party will provide to this Board by close of business on January 27, 1987, its partially completed response and advise the . Board of a reasonable date certain on which its written response can be completed. In view of the technical nature of the issue, the Board will determine the prima facie issue at hand through written pleadings. No oral hearings to supplement written responses are anticipated. IT IS SO ORDERED. FOR THE ATOM SAFETY AND LICENS GB0$RD k} Helen F. Hoyt, Chairpersory" i Administrative Judge Dated at Bethesda, Maryland this 7th day of January 1987. Although prima facie is not defined in 10 CFR 2.758, one Licensing Board has found it " reasonable to equate ' 3 rima facie' showing with
' substantial' showing." Carolina Power & .ight Company and North Carolina Eastern Municipal Power Agency (Shearon Harris Nuclear Power Plant), LBP-85-5, 21 NRC 410 (1985). We believe, however, prima facie to mean evidence of a sufficient nature that would cause reasonable minds to inquire further.

The Board believes that in the best interests of all parties and the Board, we should clear the deck for,a period of seve:al weeks to permit the 'arties p an unencumbered period to respond to Applicants' petition unoer 10 CFR 2.758 and 10 CFR 50.47(c) to reduce the plume exposure pathway emergency planning zone to one mile. The resulting hearing schedule reafsfon will allow the Board time to consider pending contentions and responses and further advance the date for discovery to commence. As we noted in our January 7,1987 Memorandum and Order, the parties are directed to respond to the issue
. g of whether a prima facie showing for a waiver has been made by the 4pp. Applicants' petition.
.L w I- .
,- 2 In revising the hearing schedule, we have used the same time frames between the various events leading to comencement of hearings as were l
set forth in our December 4,1986 order. We begin with the next' event in the sequence leading to the hearings which is the Board's ruling on contentions and the comencement of discovery. We encourage the parties to respond to requests for information prior to commencement of discovery on February 13, 1987 whenever possible. The new dates are as t follows: Date Deadlines i February 13, 1987 Board Order ruling on contentions, discovery comences. March 6, 1987 Discovery closed (last discovery . request due). March 19, 1987 Answers to last interrogatories due within 14 days after the close of discovery. March 26, 1987 Deadline for motions for sumary disposition on late-filed Rev. 2 Contendons admitted or for other contentions as to which circumstances have changed such that sumary disposition is now appropriate. April 16, 1987 Response oppo~ sing or supporting motions due within 20 days. April 27, 1987 Opposing parties'may file responses to new facts and arguments presented in statements supporting motions for sumary disposition. May 11, 1987 Board Order ruling on =ction: for sumary disposition. May 21, 1987 Prefiled testimony due 10 days after Board ruling on motions for sumary disposition.

.t +,
3 No sooner than Hearings commence. May 28, 1987 (Date depends on arrangements for spaceandlocation.) The Board again directs that service of papers relating to offsite emergency planning contentions be effected by express mail or personal delivery in any instance where nomal service would not result in actual receipt of those papers on or before a deadline for the filing of those papers. As has been thih Board's custom,. the date for filing of any pleading means that the pleading be delivered in hand to the parties and ^
~4kis Board on that date.

) Docket Nos. 50-443-OL-1 PUBLIC SERVICE COMPANY OF ) 50-444-OL-1 NEW HAMPSHIRE, E &. . ) (Onsite Emergency Planning
) and Safety Issues)
(Seabrook Station, Units 1 )
.and 2)
.t ORDER The Comission has decided to review ALAB-853 sua sponte to consider a single issue: whether as a matter of law or policy a utility applicant should be required to submit a radiological emergency plan (either a governmental plan or a utility plan) for the entire emergency planning zone (EPZ) for the facility before any operating ifcense may be issued. The n Commission specifically notes that our taking review does not indicate any position on the merits of the issue. Since the Appeal Board!s interpretation of 10 C.F.R. 50.33(g) in ALA8-853 would be subject to being
- modified or overruled by the Comission, we view it 'as appropriate to resolve the issue now so that a decision on low power ifcensing can be made with Comission guidance in hand. It is undeniable that this matter engages oroad public concern. Accordingly we find that the Commission 87eg %%
(fT -
.. . 2-itself properly should consider and deliver the final agency decision on this issue and should do so before any low power license is issued. In light of the sp;:ellate record already made on the interpretation of 10 C.F.R. 50.33(g) before the Appeal Board, the Comission does not require briefs at this time. However, the following posissive briefing schedule is established for any party who wishes further to develop before the Comission its position on this issue. Page limits on filings are indicated in parentheses. All filings shall be served by hand or by overnight express. By January 21, 1987, any party, including staff if applicable, advocating revision of ALAB-853 may file. (20 pages) By January 27, 1987, any party, including staff if applicable, advocating upholding.ALAB-853 may file a response. (20pages) By February 3,1987, any party, including staff if applicable, advocating revision of ALAB-853 may file a re71y. (10 pages) The Licensing Boards may, of course, make any necessary adjustments to their schedules that fairness dictates.to accomodate the Comission's expedited briefing schedule. The Comission by this order stays the Director of Nuclear Reactor , Regulation (NRR) from authorizing low power operations at the Seabrook facility until the Comission's review is complete. Comissioner Carr disapproved this order and would not have taken review. 4
