TIIC CifAIPJ4AN. What is the basis for it? Why tnat particular tcrainology? MR. TILFC3D. It is simply a desertitive phrase that i n ec;..nonly roccgnized by investigators in this scrt of study. Taal is the name of an active volcano-
, which forms a part of this line. The fracture zonc indicatec that it is a line along which the earth's

surface is broken ccamon y. And we knew in this ins-tance that 6his is a :one or coastal extension that is - two sidcc have fallca apart and therefore the rgocions

A way of checking this deterministic talua-tica is to an attempt a probabilistic evaluation to see if the recults are comfortable. In such a process you study thehistoricals,eismisityoftheregionyoucountallof thecarthqdakesthathaveoccuredandyoudeterminetothe extehtpes'sible.theenergyreleasedduringthoseearth-quhs and keep in mind that in the Philippines you have a record t at is longer than 400 years aid that record is alcost Etdice as long as the record 1 -t is available tousinthhUnitedStates.

May we know if there are any other additional exhibits to be presented by Westing-house panel among those to be amended or corrected' or otherwise submitted? MR. FERG. Mr. Chairman, I would like to re- , submit the third page of Exhibit "14-B". I failed to inelude the footnote on the copy I turned in yesterday. I want t.1e footnote to show that that information was reconstructed, using the U.S. NRC report NUEG-0560. THE CHAIRMAN. So, this is an amendment to the third page of "14-3-1". MR. FERG. "14-B-1".

And perhaps, it might be useful if we were to serve that particular exhibit so that the Commission for a moment because I and others would look at that would like to make that a point. THE CHAIRMAN. Very well, reproduce that Exhibit "14", NPC. MR. TORRES. Mr. Chairman, in yesterday's proceedings, there was a question on the role that EDASCO plays with respect to ascertaining or verifying that the design site characteristics and parameters that they have developed from the NPC are being used e e.. e O
Commission on Nuclear Reactor Plants I2 July 1979 e li 30 pm - 2 : 00 pm Page 7 in the design and contruction of this plant. THE CHAIRMAN. And carried out. MR. TORRES. Ani carried out. And if the Commission pleases, since I furnished the answer to that question, I would like to make a short statement to further clarify those made 3esterday.
~
THE CHAIRMAN. You may do so. MR. TORRES. In assuring the safety of the plant after the site characteristics are determined a'nd furnished to the designer, the owner -- that is the NPC -- the designer, manufacturer and the constructor of this plant -- that is the Westinghouse -- the re-gulating agency, the Philippine Atcmic Energy Com-mission and the cperator which will te the NPC, in order that they may assure that the installation can be constructed and operated withcut posing undue risk and hazard to the health and safety of the public, 6 m MO i etc cc
Commission on Nuclear Reactor Plants 12 July 1979 - 1:30 pm - 2:00 pm Page S must right from the beginning assure that these pro-cesses of utilizing the parameters developed from the i site investigation are indeed inputed and utilized by the designer. The way this'is done and the way the consultant plays its part can be briefly described - as follows:
. Before the regulating agency -- that is, the Philippine Atomic Energy Commission -- grants the owner a construction permit, the owner has to submit a docu-ment which shows that among others the design of the structures, the components, equipment and system will comply with the design criteria that the regulatory body has issued and which must be complied with. This docu-ment is part'of a more extensive one that covers other subjcets. And in the preparation or submission of this proof to the regulating body that such is the case, this is embodied roughly in one volume of a 16-volume 6
m
Commission on :Juclear Reactor Plants 12 July 1979 - 1:30 pm - 2:00 pm Page 9 report that we have submitted. Ir this perticular volume, which is also one of the chapters, we show that we have -- that is, the National Power with tne assistance of its consultants, EBASCO -- determined and confirmed that the identification, description of the systems and the utilization of the data and, in particular, with respect to the question yesterday, the' use of the seismic information that has been estab-lished will be reflected in the design and that the right kind of de' ign analysis and design procedures and methods will be used. On the basis of this docu-ment which had been submitted to the Philippine Atomic Energy Commission and the evalua*f- ;f this report, the National Power Corporation has been issued a constructive permit. Now, during the course of the design and construction 4 1 e g - M
Commission on Nuclear Reactor Plants 12 July 1979 - 1:30 pm - 2:00 pm Page 10 of the facility itself, the National Power Corporation has in its organization units thac continuously monitor and assure that these are being done in accordance with our commitment embodied in this document submitted to the regulatory body. In this respect, EBASCO advisers are piso utilized. And yesterday, I think, the question was directed to the particular activity going on in the field on how EUASCO plays a role in this process of seeing to it that the constructio.7 will be inaccordance with the criteria and ccnditions that are imposed on the design of this project. At the field, it is not the EBASCO man alone who does this. It is really NPC's responsibility and it has a construction group that performs this. How-ever, because we have available to us the exp.rtise of EBASCO, we see to it that they have a man assigned through the field so that we have advisory services 0
._ _ m w-D
Commission on Nuclear Reactor Plants 12 July 1979 - 1:30 pm - 2:00 pm Page 11 available on a day-to-day basis. It is with respect to this that we have brought this afternoon, Your Honor, the EBASCO man in the person of Mr. Elliot. who will be alsS available if the Commission pleases to question him. THE CHAIRMAN. Will you please verify if Mr. Torres has been sworn in connection with his position paper? (Af ter a pause.) Not yet. He was sworn in connection with the dissertation. MR. TORRES. Dissertation. THE CHAIRMAN. Please swear Mr. Torres. CLERK. Do you swear to tell the truth, the whole truth and nothing but the truth in this investi-gation? MR. TORRES. I do. THE CHAIRMAN.

Commission c.. Nucicar Rcactor Plants 12 July 1979 - 1: 30 pm - 2 : 00 pm Page 12 MR. TORRES. Yes, sir. THE CHAIRMAN. You stated that there is an E3ASCO man and there is an NPC man charged with the verification and checking of the construction to sce to it that it complies with the EBASCO recommendation? MR. TORRES. There is an NPC organization, not only one man. THE CH7.IRMAN. !!r. Elliot is the EBASCO man? MR. TCBRES. Yes, Your Honor. THE CHAIRMAN. And who is the head NPC man? MR. TORRES. We have at the site, uncer our site manager whom you have met before under a cons-truction division headed by Mr. Eleuterio Gatus. THE CHAIRMAN. Eleuterio Gatus.

Cerc. mission on ?:uclear Reactor Plants 12 July 1979 - 1:30 pm - 2:00 pm Page 13 MR. TORRES. Gatus. THE C!! AIRMAN. All right. So, Elliot and Gatus. Now, Mr, Tilford, you may continue with your dissertation. May we have the exhibit? The Commissioners here have not been given any copy. We have the figure marked as Exnibit "14", NPC, being flashed on the screen.
.aase proceed.
MR. TILTORD. Since the news media df not put my records to this ficare correctly, Mr. Chairman, I thought of the porribility that their misunderstanding might be more ..despread. If I can refer to the lower lef t of the figure to the note that you have, that note reads:
" Cont. curs and numbers at ridge point represent horizontal acceleration expressed as presented gravity with 99.5% probability of not being exceeded in fifty (50) years. This is equivalent to a return period of M
'w=,
commission on Nuclear Reactor Plants 12 July 1979 - 1:00 pm - 2:00 pm page 14 10,000 years." 4 I would like to explain that that means that an earthquake affecting the site'with accelerations greater than .26g has a return period of 10,000 years. This does not mean that smaller accelerations can occur during shorter time spent, tiam is, an earthquake could cccur next week, yielding an acceleration of .lg. But this simply means that at a high level of probability, these values will not be exceeded in fif ty (50) years, and that is another way of expressing a return period of one in ten thousand years. t Before we move on away from this figure and this subject, I would like to correct something that I mis-stated yesterday. I reported to you that the horizontal accelerations experienced in Cotabato during the August 1976 earthquake represented .085% gravity. I indicated to you that this was exactly 140th, the

Before I move on away from the issue of seismicity, I would like to make one other point. [he1971 additional,theNationalStructureofCode for Buildings in the Philippines which was af t.er the 1976 Mindanao earthquake, would require that in ccm-pliance with the Code, if you are building a one or two-story building on Bataan, the horizontal design acceleration would be between .08 and .lg, depending on the type of bracing system being used, and I simply point this out to suggest in one more way that I 1) s't,1

I think t hat concludes my remcrks on the ay subject of sef amicity and I am sure that there m this be question', which I should try to address at point.

May I ask if you know if this is the f'est site that you were asked to make a study with respect to' nuclear plants in the Philippines? MR. TILFORD. With respect to nuclear plants in the Philippines, this is the first nugicar plant and, , therefore, this is the first site. MR. BAUTISTA. You are referring to the site at thpot point, Morong, Bataan? MR. TILFORD. We earlier contributed to a study of a' number of potential sitts in Central Luzon. The site that was finally selected and that we actually confirmed was the Napot point site. MR. BAUTISTA. Did you not study another site semewhere in Bagac or seventeen (17) kilometers away from Napot point?

This was the site that was considered to be the primary site at the time EBASCO was engaged to ec.mplete the siting evaluation. We call that Bagae 1. . That site was near, as I said, let us say, three (3) kilometers at the existing housing site. MR. BACTISTA. Why did you choose the Bagac site? MR. TILFORD. That site from the point of view of the development of a nuclear plant has a number of ailments. MR. BAUTISTA. Will you enumerate what are these ailments? MR. TILFORD. First, the site ground surface was an elevation of two (2) meters above sea level, sir. That is an entirely unacceptabic great level for a nucle.ar
.k plant in this kind of con'dition because of Tsunami. This '
t site was located in flood point of two rivers which l

Ccamission on Nuclear Reactor Plants 12 July 1979 - 1:30 pm - 2:00 pm Page 20 - diccharge into the South Chin; sea between the present housing area and tha't site. The flooding in those rivers t . during the monsoon season is a continuing major pr'oblem for ready access to any site. Asie, it is located on that flat plane which would have created a need to develop , an enormous system of devotion around the site. The site was located in a saturated ground with essentially twenty (20) meters around consolidated sediment underlying the ' land surface. It was some six hundred (600) meters from the seashore. I have asked you to v..sualize then an excavation twenty (20) meters deep and uncensolidated luvium which would leave you eighteen (18) meters below sea level at one founding level of the plant.
- hey were not only the safety issues associated with that, but of course, the very real construction and design problems that would be asscciated with it. You 'could be trying to pump e

/
The site was not a highly desirabic site from many pcints o f view. MR. BAUTISTA. When you made that study at Bagsc reint, was tr.e housing site alread.y under construction? MR. TILFORFD. With the cooperation of MpC, we were able to get constructed for our use and study sixk6) temporary pre-cast buildings which we used to house our geology-seismology and environmental staff which at one time are occupied with some twenty (20) of our people. There was no permanent construction at the existing housing area at any time during the carrying out of the study. MR. EAUTISTA. Tha t is all. THE CHAIRMAN. Please proceed to your next one. a O
Commiss4.on or ue 12 July 1979 - 1:30 pm - 2:00 pm Page 22 c MR. TILFORD. I will make reference now to the CO:;VOL re.=,anse to the Cr mission. I THEI CHAIR:!AN. It this a new exhibit? MR. TILFORD. Yes, sir. This is a new exhibit. I believe it will be No. 15. , THE CI!AIRM.AN. Is that the correct number, Exnibit "15", NPC? MR. TILFORD. You can identify this exhibit as
" site-looking air-blown radar museum". The Commissien is most welcome and, of course, invited to look at this more closely. There is a lot of information in it.
I would like first, just briefly, to address one of CONVOL's most important comments as we view it. We will address each of their comments, but let us go to their response No. 5 initially.
"CONVOL believes that eruption f rom any of the volcanic complexes in the area is possible not only fren h - - ~ ~

Mariveles. This possibility is exemplified by Taal. It did not only crupt f rom the main crater in 1911 cruption cut also recognized ncmcrous parasitic craters; . for- example, Benintiang Manti and Benintiang Malaki alternately erupted before 1749 but was able to make open its southwestern plank and posted the eruptions from 1965 to 1977." Now, let us move at Taal for a moment. I regret that in this particular response, we are unable to agree with CONVOL. CONVOL mentions that the main cratcr of Taal on volcano island was the site of the 1911 cruptions. This was confirmed. There are ...

. MR. TILFORD. That is a correct inpression, sir.
The desiEn cecoleration for the plant at Bataan is one of the highest accoleration for any nuclear plant in the Iworld. That is true because the plant is located in 6 a region which is seis=ically active and in which there are faults. I have probably conplicated the issue un-necessarily by, stating that the Taal fracture line is a i zo.no of extension which tends to reduce or attenuate earthquake notions. If you will forget, sir, that I said that because it is probably not naterial at this point. Then you can continue with your i=pression that the fact, that a region contains active capable faults thus, require more careful address to earthquake. That inpression is correct. r31. var,qUEZ.

' MR. TILFORD. Yes. Bataan as a part of the Philip-pines and the Philippine archiepelago is Eenerally consi-dered to be one of the more active areas of the world as f ar as volcanies and seismisity is concerned. The fact rennine!that like California, in the western United . l States, it is possible to select sites where sensitive
't installations can safely be built. And the Bataan penin-sula and, specifically, the Napot point site, in our professionni judsnent, is probably the best nuclear power plant site in Central Luzon, largely because of its re-latively low historical seisnisity.
MR. VASQUE3. And that is precisely the reason why you recen= ended that the site of the plant be such that it will withstand the strongest earthquake? MR. TIL?ORD. Yes, sir. t MR. VASQUEZ. I have no more question.

MR. TIL?OED. That is correct. MS. BAUTISTA. Now, just to catisfy questions fren our conio$ people, the can in the streets, and since you said, you were able to otudy different sitea for a nuclear power plant in the Philippines, particu-larly, in Central Luzon, the connon question ic, why una not the nuclear site rather chosen the Sierra Madre Mountain or the Cordillera Mountain? What would you answer ne? MR. TILFORD. Firstly, the seis=ic risk in that region ac shown on inhibit "14", is hi E her than the ceisnic rick at Bataan. THE CEAIEMAN.

You really only have to be able to distinguish between the colors: red, white and green. Rod is the area of hiS her seisnic risk; white is an crea of conewhat lower seisnic risk; 6reen is the area of lowect seisnic risk in this area. That is the prinary reason, sir. hR. haUIibTA. So that when you =ade your recon-nendation that the Bataan site is the nos logical and safe site for a nuclear plant, you have considered all the othc5 sites or pinces in the island of luzen? MR.

The result of our studies, and they were indeed ex-haustive, (in cur view, at 1 cast that exhaustive, and pro-Lahly raore exhaustive than any study that have been performed anywhere in the world for this type of project) were that 6 1 wVI\ of the Napot point very effectively protected it frt'm the very rer.ete possibility of having to facc the hazards of new vol-canic flows of any type from the volcano.

CILP.0RI: I did not say that. The volcanoes have been defined by COMYOL as dormat. As considered by L3ASCO, and as reported Gn in the TSAR, uc cannot preclude the possi-bility of volcano activity associated with the volcano, licw-et er, en the basis of very exhaustive samp]ing and scientific study, we have euncluded that the probability of such an escat is highly remotc.

I could explain 8 possibly the earlier question concerning the suitability of t he Bagac site with my service preamble to my answer to your question.
, In February of 1975, Mr. Tilford and I came to the Philippines for the first time to make an ocular ins-k pection of the site arca and to review the results of the on-going field programs.
During that visit, we inspected the test pits that had been excavated. No observed the enrcs that had been recovered during the drilling process. We chscrved the fact that cach of the holes that have been drilled was producing water under pressure at volumes in the order of 80 to 100 GPM. This water was heated, h ving an average temperaturc possibly in the vicinity of,115 degrees and was alkaline in naturc. 1 mentioned earlier that we had concern 3 regarding the suitability and stability cf the materials. I had
. inn.cred earlier that we were concerned about the flooding of t he excavation by the Payong and the Cabayo rivers.

t Ka. GILMC3E. I was attempting to answer your earlier question by showing this slide, Mr. Justico. This photograph is also taken from the bridge looking upstream to the Kabayo river showing the Kobayo river in flood during the monsoon season. 'ahat you recollect havicg seen earlier is a relatively small stream carryir.g approxi-mately one cubic foot water per second or in the order of 500 galloon per =inute in the dry season.

.\o. 7?
MR. IlE ALY. Yes, Mr. Commissioner, hith your indulgence, Mr. Tilford is prepared to handle that question. Tilli CIIAIR.n FAN. Who is he? MR. IIEALY. Mr. Tilford. Tile CilAIRMAN. Oh, finc. We call MR. Tilford ()] q ,) ; j g g m back to the rostrum, MR. IIEALY. Thank you. $k k f ,. Tile CilAIRMAN. Proceed. MR. TI Ll?ORil. I will try t o honor t he Commission's wish for brevity. The historical earthqt akes in the site region were examined to determine the scismic design hasis for the nnetear plant site. We have used the early data, which we have mentioned earlier is unusual in the world, showing that you have a very long carthquake history, count ing to some 400 years stretching hack to the late 1500s, early lo00s. We have used all of that historical information in developing the scismic design hasi3. We have also used all of the available instru.nentally recorded data and we have included all of t hat data in our eartiatuake catalogue. Liasi'ay, e we concur with the list of locally felt earthquakes repo.ted to you by the l'ACASA response to the question to the extent that if there is any difference 0 1223 001 o m em em
Con. mission on Nuclear Reactor Plants 13 July 1979 - 10:30 a.m. ; . til ; i Page 3 between the list that they have given you within the last few days and the one which we have submitted to you, it is lieeause of a definition. We have listed only those which were listed as having been felt in Bataan ar.d report ed f rom Hataan or they have included a few events which were not spccifically reported from llataan but which could reasonably be expected to have been felt in Bataan and we concur in that approach as well. Basically, the history of rthquakes in the parti-cular site of this plant is very slight. The Bataan peninsula occupics what almost might he described as a windbw, an open space, in the historical record of e.'ismicity in Central Luzon and is almost unique in Central Lu:on in that aspect. There have been very few e.arthquakes which have created any destruction on Bataan, i.e t me read /you very quickly the description of the worst of those which we considered to be the 1852 carthquake of Septemhcr 10th. The repor. states that Balanga su f fered cons iderably. The royal house had some cracks and fractures. The t'hurch t ower and turret roof of Orion were ruined. The entare roof, the choir, and part of the tower of the church
.'i Orani were down. The churches and pari.h houses ot Wu e.t y , Pilar, Mariveles and Balanga suffered considerah c loss.

The nuclear plant is, of c'ourse, on the other side of the peninsula on hard competent rock. I would conclude my remarks in the interest of brevity at that point and be happy to try to address any questions of the Commission. TilII CllAIRMAN. Questions by Justico Vasquez? JllSTICl. VASQUll .

Mr. Tilford, wherc did you get your naterials relative to your response to Quest ion No. 7? MR. TILFORD. The information availabic on the earthquake history of the region coacs primarily from the catalogue of Raf fety and the subsequent catalogue, 1 believe, cf Sobia and others, prepared by local people, primarily from records of the church. That record hcgins, I think, with the first entry, which is 1599 or 1000, and is complete through the early p.i r t of this century, instrumentally reco ded carthquakes are available from the US National Ocean and Atmospheric Administra-tion tape files. We relicd on that file a good Jeal in 8 1223 003
