      \                       1975.

8 9 After the hearing the Regulatory Staff requested 10 that the Board defer its decision until the Sta ff could 11 issue its position on the applicability to the South Texas Project, a new Commission regulation on "as low as practicable' 12 radiological releases. 13 The record was later reopened to receive the new 14 information and the decision was issued on August 7, 1975. 15 That partial initial decision authorized the issuance of a 16 limited work authorization to the applicant. This meant that 17 the Applicant could proceed at its own risk to perform certain 18 preliminary work at the site. 19 On October 24, 1~75, the Board issued the notice for the 20 evidentiary -hearing on health and safety issues. I read 21 those issues at the prehearinq conference on February~' 22 1975, but since some time ha~ passed, I will repeat them 23 quickly now: 24 ,!.,:~ . Jerol Reporters, Inc. We must determinine, one, whether,in accordance with 25

I 4( - I bw2 1i l I have described the p r opos ed design of the f2.cllitie.'-', .i.:1cluc:(;: 2J 3 but not limited to the principal architectur a l and 4 engineering criter ia for the design, and have identi fied 5 the major features or components incorporated therein for 6 the protection of the health and safety of th e public; 7 b, such further technical or design information as may be required to complete the safety analysis and which can 8 reasonable be left for later consideration, will be supplied 9 10 in the Final Safety Analysis Report; c, safety features or components, if any, which require research and development 11 have been described by the Applicants and the Applicants 12 have identified and there will be conducted a research* 13 and development progra~ recently designed to solve any 14 safety questions associated with such features or components; 15 and, d, on the basis of . the fore.going there is reasonable 16 assurance;that, (1) such safety questions will be 17 satisfactorily resolved at or before the latest date stated 18

application for *completion of constr\1ction of the in the 19 proposed facilities; and (2), taking into consideration the 20 criteria contained in 10 CFR Part 100, the proposed facility 21 can be constructed and_ operated at the proposed location 22 without undue risk to the health and safety of the public.

23 Number 2, whether the Applicants are technically 24 A-:ce _Jerol Reporters, Inc. qualified to design ad construct the proposed facility. 25

b'.-i3 IIlj I I Number 3 , whether th o Applicants are f inancially I 2 qualified t o designilld construct the proposed facility; and 3 Last, number 4, whether the issuance of permits 4 for construction of the facility will be inimical to the 5 common advantage and security or to the health and safety 6 of the public. 7 The notice stated that the public is invited and 8 the limited appearance statements will be accepted. 9 And oral presentations will be limited to five minutes, but 10 written statements without limitation on length, may be 11 inserted in the docket. We will call for limited appearances shortly. 12 I have introduced the Board on two prior occasions, 13 but some of you may be *attending for the first time today. 14 I amElizabeth Bowers . . I am a lawyer. I am 15 a member of the Kansas Bar and for the last 24 years I 16 have beeninvolved in federal administrative hearings. The 17 first 15 years as a trial attorney, and since then as a 18 presiding officer under various titles. 19 On my left is Mr.

Frederick J. Shon. His 20 education and experience has beenin the field of nuclear 21 reactors. Prior to joining this panel on a ful~-time basis, 22 he was the Assistant Director for Nuclear ~acilities, Division 23 of Operation Savety, U.S~ Atomic Energy Commission. I 24 Ace-, .,derol Reporters, Inc. think I failed to mention that his background, his 25

bw4 educa ti onal b a ck g r ound , is bo t h in phy s i cs a nd i,1 2 e ng ineerin g . 3 On my right is Dr. Ca det H. Han d, wh o is t he 4 Director of the Bode ga Bay M.~rine Labor a tory for ,t he 5 University of California at Berkeley. I am going to tell 6 a little secret that I was able to find out from Dr. Hand 7 that I think you might be interested in. One of the 8 reasons that Emperor Hirohito wanted, to visit America was to 9 meet Dr. Hand, who he has been corresponding with for many 10 years in the area of marine biology. So the Emperor invited 11 Dr. Hand to San Francisco and they exchanged qifts and had 12 an hour's discussion through an interpreter on marine biology, 13 which I think is a very interesting thing. 14 DR. HAND: We didn't say a word about nuclear 15 reactors or bombs. 16 MRS. BOWERS~ I would ~ike to now call for 17 appearances of the parties. 18 Is the Applicant present? 19 MR. SCHWARZ: Yes, Mrs. Bowers. With the Board's 20 permission, I would suggest I remain seated with reference 21 to the use of the microphone. MRS. BOWERS: Fine. 22 MR.

The book included the qualifications of each of 12 Applicant's primary witnesses, including those witnesses 13 who will sit on the panel of technical experts presented by 14 the Applicant for responses to the questions previously 15 submitted by the Board and other questions that the Board 16 may have. It shall rely on these materials and these 17 witnesses in the presentation of our direct case. 18 As a matter of procedure, subject to the Board's 19 approval, of course, we propose the identification, swearing 20 and qualification of each of Applicant's primary witnesses. 21 At that time, we propose to identify.

Re: Opening Statement on 3e~alf o f the South Texas Pr e ~ ct Participants and the Project Manager 1 I. Introduction. 2 My name is George W. Oprea, Jr. I am Execu-3 tive Vice President of Houston Lighting & Power Company, 4 and I am responsible for that Company' s nuclear program. 5 A resume of my educational and professional qualifica-6 tions has previously been received in evidence. 7 I wish to take this opportunity to welcome 8 you again to South Texas. 9 The purpose of my testimony is to describe 10 briefly the background for the South Texas Project and, 11 in a general way, the undertakings of the Participants 12 in support of the Project. These Participants are the 13 City Public Service Board of the City of San Antonio, 14 Central Power and Light Company, the City of Austin and 15 Houston Lighting & fower Company. I shall also address 16 the undertakings of Houston Lighting & Power Company, 17 as Project Manager, in establishing its own capability 18 to support the design, construction and safe operation 19 of the South Texas Project Nuclear Generating Station. 20 In addition, I shall sponsor the formal Application. 21 II. Application. 22 The Application for Construction Permits and 23 Operating Licenses, as amended by Amendments 1 through 24 3, Applicant's Exhibit No. 7, was prepared under my

1 supervision by representatives of all Participants. 2 The statements contained in the Application, as so 3 amended, are true and correct to the best of my knowledgE 4 and belief. 5 Amendments 2 and 3 to the Application, which 6 were filed on October 20, 1975, and October 30, 1975, 7 respectively, brought up to date the information 8 previously contained in the Application. They provided 9 the current cost estimates for the South Texas Project 10 Units 1 and 2, more current information as to the 11 financial qualifications of the Participants, the 12 currently planned net generating capability of the 13 Participants, and miscellaneous information, such as 14 memberships of Boards of Directors and principal officers 15 The Application, as amended, fully documents the financia 16 qualification of the Participants to design and construct 17 South Texas Projects Units 1 and 2. 18 III. Background for the South Texas Project. 19 The areas served by the four Participants in 20 the Project encompass about the southern one-third of 21 the State. According to the last census, these areas 22 include four of the eight largest metropolitan areas in 23 the State. It is each Participant's responsibility to 24 provide the electricity which is needed to support the 1 growth and the living standards of the c itizens of the 2 area it serves. Moreove r, the Partic i pants are respon-3 sible for providing this electricity at a reasonable 4 cost and in a manner that protects the environment as 5 well as the health and safety of those persons in the 6 vicinity of the proposed facility. I believe that each 7 of the Participants has been successful in meeting its 8 customers' needs and in being a good neighbor to those 9 who live in the vicinity of its generating facilities. 10 We are proud of this record and intend to perpetuate 11 it. 12 The currently planned net generating capability 13 of the four Participants in the Project through the 14 year 1984, is shown in graphic form in amended Exhibit 15 III to the Application. By comparing this projected 16 capability with that included in the Application as 17 originally filed in 1974, one notes certain reduction 18 in the facilities planned by each of the Participants. 19 Since the hearing on environmental and site 20 suitability matters the only significant reduction 21 results from Houston Lighting & Power Company's recent 22 decision to postpone indefinitely the construction of 23 its Allens Creek Nuclear Generating Station, planned 24 for a site in Austin County, Texas. None of the 1 Participants in the South Texas Project, other than 2 Hou ston Lighting & Power Company is involved in the 3 Allens Creek project. Therefore, the deferral of that 4 project does not affect the plans of the other Partie-s ipants in the South Texas Project. 6 From Houston Lighting & Power Company's 7 standpoint, deferral of the Allens Creek project h as 8 made timely construction of the South Texas Project all 9 the more important. This action further assures our 10 ability to finance the remainder of our construction 11 program, including Houston Lighting & Power Company's 12 30.8% share of the South Texas Project. As of December 13 31, 1974, Houston Lighting & Power Company's assets had 14 a book value of $1,692,088,000. The Company's 1974 15 revenues were $486,837,000, all attributable to electric 16 operations. The bonds of Houston Lighting & Power 17 Company are rated AA by both Standard & Poor's Corpora-18 tion and Moody's Investor Service, Inc. 19 The other Participants in the South Texas 20 Project are likewise financially qualified to undertake 21 their responsibilities with respect to the South Texas 22 Project. Central Power and Light Company's assets were 23 valued at $603,972,000 as of December 31, 1974, and 24 Central's 1974 operating revenues were $223,595,000. 1 Central's bonds are also rated AA by both Standard & 2 Poor's Corporation and Moody's Investor Service, Inc. 3 Central is a wholly owned subsidiary of Central and 4 South West Corporation. As of December 31, 1974 the 5 consolidated balance sheet of Central and South West 6 and its subsidiaries reflected assets of $1,788,708,000. 7 The City Public Service Board of San Antonio 8 and the City of Austin are both municipally owned 9 electric systems, serving metropolitan populations of 10 about 1,300,000 and 335,000, respectively. In the 11 fiscal year ended January 31, 1975 the City Public 12 Service Board of San Antonio had electric system revenues 13 of over $137,000,000. Its electric and gas system 14 bonds are rated AA by both Moody's Investor Service, 15 Inc. and Standard & Poor's Corporation. During the 16 fiscal year ending September 30, 1974, the City of 17 Austin had revenues from sales of electricity of over 18 $57,000,000. Austin's revenue bonds enjoy a AA rating 19 by both of those investment services. 20 Each of the Participants is mindful of its 21 responsibility to provide adequate financial support to 22 the Project. Each will finance its proportionate share 23 of the Project, and, while the sources of funds will 24 vary among the Participants, they will include funds on

-s-

1 hand, retained revenues, short term lo a ns and commercial 2 paper, and the sale of securities as required. 3 Less than one half of one percent of the 4 common stock of Houston Lighting & Power Company and of 5 Central and South West Corporation is owned by non-6 residents of the United States. 7 IV. Undertakings of the Participants. 8 As I indicated to this Board last April 9 during the portion of this proceeding involving environ-10 mental and site suitability matters, the Participants 11 in the Project approached this joint undertaking in a 12 deliberate manner. In the latter part of 1971 a feasi-13 bility study was undertaken to determine the desirability 14 of constructing and operating a jointly owned generating 15 facility. 16 By the end of 1973 these Participants had 17 entered into a formal agreement providing for a jointly 18 owned and operated nuclear generating facility. Houston 19 Lighting & Power Company was selected as Project Manager 20 and charged with designing, licensing, constructing, 21 maintaining and operating the Project facilities for 22 the benefit of itself and the other Participants. 23 V. Undertaking of Project Manager. 24 Houston Lighting & Power Company fully I*

1 recognizes that as Project Manager it has the ultimate 2 responsibility for the safe design, construction and 3 operation of the South Texas Project Nuclear Generating 4 Station. In order to discharge this responsbility, we 5 commenced developing our in house nuclear capability in 6 1971. This involved additional training for some of 7 our existing personnel and the hiring of a number of 8 new employees who already had experience in the nuclear 9 phase of the electric industry. I participated directly 10 in assembling and organizing this in house capability 11 which continues to report to me. 12 The Project Manager's Staff is complemented 13 by a strong support team comprised of Brown & Root, 14 Inc., the Architect-Engineer and Constructor for the 15 Project, and Westinghouse Electric Corporation, the 16 supplier of the nuclear steam supply systems and the 17 fabricator of the *fuel for each of Units 1 and 2. 18 Brown & Root is known favorably to the Project Partic-19 ipants as a result of its experience as a designer and 20 constructor of fossil fuel facilities and through its 21 reputation in the engineering and construction of other 22 large and complex facilities. Brown & Root brings to 23 this Project substantial nuclear experience, both from 24 the addition of personnel within its organization and 1 the use of experienced subcontractors such as NUS 2 Corporation, Woodward-Clyde, Consultants and others. 3 Westinghouse Electric Corporation needs no 4 introduction to the nuclear power industry. It is a 5 recognized leader in this field. Dr. Sumpter will 6 present a more detailed discussion of the technical 7 qualifications of Houston Lighting & Power Company, 8 Brown & Root and Westinghouse. 9 For many years, Houston Lighting & Power 10 Company has recognized the need for, and has maintained, 11 an extensive quality assurance program. In conjunction 12 with the establishment of its nuclear program, the 13 Company reorganized its quality assurance procedures. 14 Mr. D. G. Barker, who joined the Company in 1972, now 15 heads the Company's quality assurance program. He is 16 also responsible for, and in charge of, the South Texas 17 Project quality assurance plan. Mr. Barker will testify 18 in more detail as to the quality assurance plan for the 19 11 South Texas Project. Mr. Barker reports directly to 20 me. 21 I am a member of the Board of Directors of 22 Houston Lighting & Power Company and have direct access 23 at all times to the Chief Executive Officer of the 24 Company, Mr. J. G. Reese, who is also the Chairman of 1 our Board, and to the Chief Administrative Officer of 2 the Company, Mr. D. D. Jordan, who is also our President. 3 I am a member of the *.1 anagement Committee for 4 the South Texas Project. The Management Committee was 5 established under the provisions of the Participation 6 Agreement which is set forth in Exhibit I to the Appli-7 cation. Houston Lighting & Power Company, as Project 8 Manager, advises the Management Committee of activities 9 and developments concerning the Project and consults 10 with that Committee on a regular basis. On the other 11 hand, the Participation Agreement charges Houston 12 Lighting & Power Company with the safe design, construc-13 tion and operation of the South Texas Project Nuclear 14 Generating Station, and Houston Lighting & Power Company 15 has accepted and is carrying out this responsibility. 16 VI. Conclusion. 17 In summary, we have established a team of the 18 necessary talents to design, build and operate this 19 11 plant in a manner that is environmentally acceptable 20 and safe. I am proud of this team. Further, I assure 21 you that not only I, but the entire management of 22 Houston Lighting & Power Company, clearly recognize and 23 accept the responsibility of designing, constructing 24 and operating the South Texas Project Nuclear Generating 1 Station in a manner consistent with the health and 2 safety of both the workers in the plant and those 3 persons living or working in the vicinity of the plant. 4 In carrying out these goals, we h av e received, and 5 continue to receive, the full cooperation and support 6 of all of the Participants in the Project. 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 TESTI~ONY OF J .

I am Manager-2 Nuclear Division of the Power Plant Engineering and 3 Construction Department of Houston Lighting & Power 4 Company. 5 A resume of my educational and professional 6 qualifications has previously been received in evidence. 7 My responsibilities in connection with the South Texas 8 Project include the design, engineering and fuel manage-9 ment of the nuclear system, radiation protection, 10 licensing and safety analysis. 11 The Preliminary Safety Analysis Report, as 12 amended by Amendments 1 through 34, and including 13 Appendices A through F, Applicant's Exhibit No. 8 (PSAR), 14 was compiled under my supervision and direction. Some 15 of this material was prepared by Houston Lighting & 16 Power Company employees; however, the major portion of 17 the basic data was initiated and supplied by our 18 Architect-Engineer and Constructor, Brown & Root, Inc., 19 or by one or more of a number of consultants, including 20 NUS Corporation, and Woodward-Clyde, Consultants, and 21 EDS Nuclear, Incorporated. In all instances -either I 22 or one of the Houston Lighting & Power Company personnel 23 in the Nuclear Division reviewed and approved this 24 material prior to its incorporation into the PSAR.

TESTIMONY OF DOUGLAS W. PEACOCK

                       ~e:  RESAR - 41 1       My name is Douglas W. Peacock. I am Manager of 2 Reactor Protection, Nuclear Safety Department, Westing-3  house Electric Corporation . A sununary of my professional 4  qualifications has been received previously in evidence.

5 The purpose of my testimony is to provide an 6 explanation of what the RESAR-41 reference design 7 involves and an explanation of how it evolved from 8 earlier Westinghouse designs. I shall also sponsor the 9 RESAR-41 Reference Safety Analysis Report, as amended 10 by Amendments 1 through 19 (RESAR-41), Applicant's 11 Exhibit No. 9. 12 I have participated in the over-all safety review 13 of the Westinghouse design described in RESAR-41. 14 Portions of RESAR-41 were prepared under my direction. 15 I participated in the review and approval of those 16 portions of RESAR-41 which were not prepared under my 17 supervision, and for these reasons, I am familiar with 18 RESAR-41 in its entirety. The statements contained in 19 RESAR-41 are true and correct to the best of my knowledge 20 and belief. 21 RESAR-41 is a standard safety analysis report for 22 a Westinghouse nuclear steam supply system (NSSS) 23 design which was filed on December 3, 1973, and docketed 24 on March 11, 1974, by the Atomic Energy Commission,

1 predecessor to the Nuclear Regulatory Commission (NRC). 2 This submittal was in the form of an application for a 3 Preliminary Design Approval (PDA) to the NRC pursuant 4 to Appendix O of 10 CFR Part 50. 5 The issuance of a PDA is contingent upon successful 6 completion of a safety review by the NRC Regulatory 7 Staff and the Advisory Committee on Reactor Safeguards, 8 and is similar to the review given to conventional 9 custom plant construction permit applications. A 10 standard design receiving a PDA may then be referenced 11 by utility applicants for construction permits without 12 re-review by the NRC Staff with the exception of items 13 not resolved during the PDA review phase, site related 14 areas and interfaces, significant safety issues arising 15 subsequent to the PDA, any proposed modifications of 16 the standard design, or requirements arising from NRC 17 rules or directives promulgated after the PDA. 18 RESAR-41, as supplemented through Amendment 19, 19 describes the Westinghouse standard four-loop NSSS for 20 a 3817 MW (thermal) pressurized water reactor. Its 21 scope, as incorporated by the South Texas Project 22 Preliminary Safety Analysis Report (PSAR), includes the 23 Reactor, Reactor Coolant System, Emergency Core Cooling 24 System, Emergency Boration System, and various other 1 s af ety and ass oc i ate d s y s t ems incl uding in s t rumentation 2 and controls for the v ariou s s y s tem s . The ba lance of 3 plant structures, systems, components and power distri-4 bution systems are described in the Applicant's PSAR. 5 While the Sout h Texas Project license application 6 is the first applica t ion for a construction permit to 7 reference RESAR-41, the standard plant described in 8 RESAR-41 is similar in many respects to the RESAR-3 9 design [3425 MW (thermal)] which has been reviewed by 10 the Commission on license applications for the Catawba 11 plant (Docket Nos. 50-413 and 414), the Vogtle plant 12 (Docket No. 50-424 through 427), the Millstone 3 plant 13 (Docket No. 50-423), the Comanche Peak plant (Docket 14 Nos. 50-445 and 446), the Seabrook plant (Docket Nos. 15 50-443 and 444), and the SNUPPS projects (Docket Nos. 16 50-482 through 487). The RESAR-41 design is an evo-17 lutionary step from the RESAR-3 plant design and repre-18 sents design evolution of the Westinghouse nuclear 19 technology. The principal design differences and 20 similarities are summarized below. 21 The RESAR-41 reactor is similar to the RESAR-3 22 design except for an increase in active fuel length 23 from 12 to 14 feet providing approximately a 15% increase 24 in fuel loading and heat transfer area. In addition, r

1 correspondingly longer control rods have been provided 2 and the lower internals, of a design similar to the 3 basic RESAR-3 design, have been modified to accommodate 4 the longer fuel assemblies. The fuel design is also 5 similar except that it incorporates nine grids per 6 assembly rather than the eight grids in the RESAR-3 7 design. Similarly with the exceptions necessary to a accommodate the differences relating to the increased 9 system capacity and to accommodate the rapid refueling 10 concept, the RESAR-41 Reactor Coolant System is basically 11 similar to the RESAR-3 system. The reactor vessel is 12 of the design used on RESAR-3 applications with the 13 sole exception that the reactor vessel closure system 14 has been changed to facilitate rapid refueling. The 15 reactor coolant pump design is similar to the RESAR-3 16 pump but will have an increased capacity. To transfer 17 the additional heat.generated in the RESAR-41 reactor, 18 the steam generators will have longer and a greater 19 number of tubes thereby increasing the total heat 20 transfer area. The RESAR-41 Residual Heat Removal 21 System (RHRS), in providing greater flexibility and 22 operability, utilizes three cooling trains with inde-23 pendent pumps not shared with the Emergency Core Cooling 24 System (ECCS). The RHR pumps employed will be of the 1 vertical type rather than the horizontal pumps used in 2 previous designs; however the components of the modified 3 RHRS are of a proven technology. 4 The new Emergency Boration System (EBS), and the 5 redesigned Safety Injection System (SIS) are the only 6 fundamental modifications of the Engineered Safety 7 Features. The SIS design utilizes three independent 8 trains with complete separation from any function other 9 than emergency core cooling. The system components are 10 similar to previous designs with the exception that 11 vertical pumps are employed rather than horizontal. The 12 EBS, replacing the Boron Injection tank in the SIS used 13 on RESAR-3 design, is provided to mitigate the conse-14 quences of steamline break accidents. Although a number 15 of the EBS components differ from those utilized in the 16 RESAR-3 design, all are of proven technology. The in-17 strumentation and Control Systems for the Engineered 18 Safety Features and other systems are substantially the 19 same as previous designs with differences principally 20 to accommodate various system modifications. 21 A Spent Fuel Pool Cooling and Cleanup System is 22 provided in the scope of RESAR-41. The remainder of 23 the Auxiliary Systems, with the exception of the Fuel 24 Handling System and the Chemical and Volume Control I.

1 System (CVCS) are substantially the same as the RESAR-3 2 designs. The Fuel Handling System has been modified to 3 accommodate the rapid refueling provisions, and the 4 eves, basically the RESAR-3 design, incorporates a 5 number of modifications to achieve independence from 6 the ECCS and the EBS. 7 An in-depth comparison of the relationship 8 between RESAR-41 and RESAR-3 is presented in Tables 9 1.3-1 and 4.1-1 of RESAR-41. Additional insight to the 10 similarities of the principal parameters and design 11 features of RESAR-41 and RESAR-3 is presented in Attach-12 ment 1. 13 14 15 16 17 18 19 20 21 22 23 24 ATTAC~MENT 1 Comparison of Principal Parameters and Design Features of RESAR-41 and RESAR-3 Parameter/Feature RESAR-41 RES AR -3 Reactor Core Power Level (MWt) 3800 3411 Number of Loops 4 4 System Pressure, Nominal, psia 2250 2250 Total Thermal Flow Rate, lb/hr 144.7xl06 142.2x lo 6 Effective Coolant Flow Rate for Heat 138 . 2xl06 135 .8xl o 6 Transfer, lb/hr Effective Coolant Flow Area for Heat 51.1 51. l Transfer, ft2 Nominal Inlet Coolant Temperature °F 559 . 8 557 . 3 Coolant Temperature Ave rage Rise in Core 66.8 62.3 Average Thermal Output, kw/ft 5.33 5.45 Heat Flux Hot Channel Faqtor, Fq 2.50 2.50 Maximum Thermal Output for Normal 13.3 13.6 Operation, kw/ft Number of Fuel Assemblies 193 193 uo 2 Rods per Assembly 264 264 Number of Grids per Assembly 9 8 Fuel Weight (as U02), lbs. 253,675 222,739 Fuel Rod Array 17xl7 17xl7 Clad Thickness, inches 0.0225 0.0225 Clad Material Zircaloy-4 Zircaloy- 4

To date, Westinghouse field reactors have not 15 1 16 experienced any difficulty in meeting power distribution 17 limits and in controling xenon transi e nts in the Mode A 18 type of operation. 19 MRS. BOWERS: Mr. Schwarz, the understanding was 20 we would wait until later for Barad questions. And that 21 is true also in this area. 22 MR.

1' I 11 I ~ Dr. Peacock, the Board's fourth question r e ads:

                                "The Board not e s that one of the consequences of the new 12 *I 13       RESAR-41 refueling system is that fuel will be handl e d at a 14       shutdown margin of only five percent.                      How does this margin 15

compare with that generally allowed for fuel handling in 16 II reactors and cri tica1 f aci 1 i ties. at present?"

17 A. The National Standards Institute standard in 18.2 18 specifies a value of the K effectiveness should not exceed 19 a value of .95 in fuel storage systems, although no specific 20 criterion is given for the reactor fueling operation. 21 A five percent margin is adequate and is consistent 22 with what is generally allowed today for fuel handling opera-23 tions at reactor facilities. 24 I Q.

And, " (b) How many minutes warning will t he ii 11 i 9 ii operator have of impending criticality if r e liance is placed 11 I I I 10 1! entirely on nuclear instr umen tation for warning of such 11 1 1 I! criticality wheu it occurs by the most rapid po stulat ed 12 reactivity addition mechanism during refueling?" 13 .1 A. The present plan for the South Texa s Project is I,I 14

to lock out certain valves in the chemical volume control 15 system to preclude a potential for boron dilution during 1

16 I refueling. The only makeup water to the reactor coolant I 17 II system is via the refueling water storage tank. This water 18

is borated and sampled to insure adequate boration rpior to 19 the release of the reactor coolant system, thus, reliance is 20 not placed entirely on nuclear instrumentation, although it 21 will be available to warn against an approach criticality.

2 Nucl e ar Division of the Power Plant Engineering and Con-3 struction Department of Houston Lighting & Power Company. 4 A resume of my educational and professional 5 , qualifications has been previously received in evidence . 6 My responsibilities in connection with the South Texas 7 I Project include the design, engineering, and fuel manage-I 8 j ment of the nuclear system, and the radiation protection, 9 I licensing and safety analysis of the total plant. 10 The purpose of this testimony is to sununarize 11 the information regarding the technical qualifications 12 of Houston Lighting & Power Company as Project Manager 13 for the South Texas Project, as well as the information 1.4 regarding the technical qualifications of our principal 15 contractors. 16 More detailed information will be found in 17 the Preliminary Safety Analysis Report for the South 18 Texas Project, Section 13.1. You will also find addi-19 tional specific information in the attachments to this 20 testimony which I hereby incorporate. 21 Houston Lighting & Power Company is keenly aware of its special responsibilities assumed in under-22 taking the design, construction and operation of this 23 nuclear power station. 24

1 The matter of nuclear staffing has been the 2 subject of intensive consideration by our management. 3 We have, in place, a staff fully competent to execute 4 our design and construction responsibilities. Our 5 plans include the addition of further engineering and 6 operating personnel as required to assure the effective 7 design, construction and operation of the South Texas 8 Project. 9 Houston Lighting & Power Company is respon-10 sible for coordinating the overall design and construc-11 tion effort required to achieve a complete facility 12 which will provide safe, reliable and economic power. 13 The principal tasks involved in this effort include the 14 design control of the balance of plant and auxiliary 15 systems; the design control of the nuclear system; cost 16 control and scheduling functions; and finally, con-17 struction supervision. 18 These functions are performed in Houston 19 Lighting & Power Company by our Power Plant Engineering 20 and Construction Department (PPE&C} which is under the 21 direct control of our Executive Vice President, George 22 W. Oprea, Jr. PPE&C is, in turn, divided into four 23 basic groups as follows: 24 (1) The Engineering group is responsible for 1 thereof with the NSSS design. We also review bidders 2 lists, specifications, equipment selection and drawings 3 which are subject to our approval. 4 Other departments with important functions 5 con n e cted with the South Texas Project include the 6 Engineering Department, the Energy Production Depart-7 ment, the Environmental and Inter-Utility Affairs 8 Department, and the Quality Assurance Department. 9 The Power Plant Engineering and Construction 10 I Department utilizes forty-three people with engineering 11 I degrees in support of the Project. Of these, two have 12 I doctoral degrees, thirteen have Masters degrees, and 13 twenty-eight have Bachelors degrees. i The Energy Production Department has three 14 15

    ' people involved in the Project of which two have 16     Bachelors degrees and one is a registered Professional 17     Engineer.

18 The Engineering Department employs twelve 19 people in support of the South Texas Project. Of 20 these, two have Masters degrees, nine have Bachelors 21 degrees, and one is a registered Professional 22 Engineer. 23 The Environmental & Inter-Utility Affairs 24 Department employs nine people in connection with the South Texas Project, and of these nine one has a doctoral 2 d egree, five have Masters degrees, and three have 3 Bachelors degrees. 4 The Quality Assurance Department, which is 5 entirely separated from PPE&C includes 16 professiona l 6 personnel working in support of the South Texas Project. 7 Of these, three have Masters degrees and eight have 8 Bachelors degrees, and six are registered Professional 9 Engineers. A more detailed presentation regarding this 10 function is presented in the testimony of Mr. Barker. 11 Attachment A to this testimony provides per-12 tinent information regarding the technical qualifications 13 of key South Texas Project personnel including their 14 educational qualifications, experie rice and any special-15 ized courses taken in the nuclear field. 16 Attachment Bis an organizational chart show-17 ing the relationship of the organizational components 18 having responsibilities for the Project. 19 Our architect-engineer-constructor is Brown & 20 Root, one of the largest construction engineering com-21 panies in the world with over 48,000 employees on its 22 permanent payroll. Brown & Root has been intensively 23 involved in the design and construction of central 24 station thermal power plants since 1954. In the past

-s-

1 21 years it has bee 1. respo n sitlc far th~ jesign a~~ 2 co ns t r uction of 79 fossil fuel ge ne rating sta tio ns , 3 with a combin e d capacity o f over 27 , 000 me gawa t ts, in 4 s i zes ranging fr om sma ll ind u st r ial ~~ s t allati ons up to 5 units of 870 megawa t ts each. 6 In the nuclear field, Brown & Root has been 7 responsibl e for the construction o f two 8 20 megawatt 8 boiling water reactor plants for Ca rolina Power and 9 Light Company's Brunswick Station. 10 It is presently engaged in similar work on 11 behalf of Texas Utilities in the Comanche Peak Nuclear 12 Power Plant project which consist s of two 1150 megawatt 13 Westinghouse pressurized water reactor systems. 14 Brown & Root's South Te x as Project engineering 15 team is headed by an engineering p r oject management 16 group including the engineering p roject manager, the 17 assistant engineering project manager and the design 18 coordinator. The 3 engineers in the group have a 19 combined experience of 42 man-years in power plant 20 engineering and construction and specifically 40 man-21 years of experience in nuclear projects. 22 Under the project management group are various 23 support groups including licensing, documents and 24 controls, and various specific engineering discipline 1 g roups. Fo r the So uth Texa s Pro ject, Brown & Roo t has 2 d rawn from its existing pool of fos s il power plant 3 experience and from its nuclear power talent and has 4 supplemented these with expert s fr o m consu lti ng enginee r-5 ing organizations. 6 The 19 key project pers onnel for the South 7 Texas Project have a total of 163 man-years of nuclear 8 experience. The 16 key supporting personnel assisting 9 in the project h ave a total of another 224 man-years of 10 nuclear experience derived from work in 33 nuclear 11 projects. Attachment C to this testimony is an organi-12 zational chart showing Brown & Root's project organiza-13 tion for South Texas Project. Attachment D to this 14 testimony is a table showing the names of 19 key project 15 personnel for the South Texas Project together with a 16 brief indication of their educational background and 17 prior relevant experience. 18 In addition, several nationally known con-19 sulting organizations are making major contributions to 20 the South Texas Project in their areas of special 21 expertise. NUS is responsible for preparing the En-22 vironmental Report and for a number of design activities, 23 including certain auxiliary systems; primary shielding 24 analysis; containment analysis; accident analysis; 1 radiological effects analysis and licensing supp ort. 2 NUS engineering personnel now working on the South 3 Texas Project have a total of 800 man-years of previous 4 nuclear experience compiled in more than 80 nuclear 5 projects. Woodward-Clyde Consultants (WCC) are re-6 sponsible for the geology, seismology, soils engineering, 7 groundwater hydrology and soil/structure interaction 8 analysis for South Texas Project. wee has gained 9 experience from working on twenty previous nuclear 10 projects. EDS Nuclear has responsibility for pipe 11 stress analysis inside the containment and pipe break 12 analysis. They also provide support to the project in 13 the structural analysis area. EDS Nuclear has gained 14 experience from eleven previous nuclear projects. 15 The NSSS supplier is Westinghouse Electric 16 Corporation, one of. the leading suppliers of nuclear 17 systems in the entire world. As of October, 1975, 33 18 reactors of Westinghouse design are in operation in the 19 United States and abroad and 114 are in planning and 20 construction phases. Westinghouse's experience in the 21 nuclear field dates back over 30 years. This history 22 of experience is detailed in Section 1.4.3 of RESAR-41. 23 I should also mention, before closing, that 24 training programs have been planned and instituted by 1 Houston Lighting & Power Company for a large number of 2 personnel, including some not presently assigned to the 3 South Texas Project. This approach to the training of 4 engineering personnel in the fundamentals of nuclear 5 engineering will provide us with a pool of trained 6 personnel in the Company who can be assigned to the 7 project on a timely basis. It also provides a balance 8 between utility experience and nuclear training which 9 we feel is desirable. Attachment A provides an indica-10 tion of the key personnel participating in the training 11 programs. 12 In summary, I believe we have assembled an 13 unusually strong team within Houston Lighting & Power 14 Company and our principal contractors to assure that 15 the South Texas Project is well built and safely operated. 16 17 18 19 20 21 22 23 24 ATTACHMENT A Tables Of HOUSTON LIGHTING & POWER COMPANY PERSONNEL Table 1 - Power Plant Engineering & Construction Department Table 2 - Energy Production Department Table 3 - Engineering Department Table 4 - Environmental Protection Department Table 5 - Quality Assurance Department I

TESTIMONY OF D. G. BARKER Re: Quality Assurance 1 My name is David G. Barker. My position is 2 Manager, Quality Assurance Department with the Houston 3 Lighting & Power Company (HL&P). 4 A resume of my educational and professional 5 qualifications has previously been received in evidence. 6 My functions in connection with the South 7 Texas Project are the development, implementation and 8 management of the HL&P Corporate Quality Assurance 9 Program. This responsibility extends into all project 10 activities including design, procurement, construction, 11 and operation. 12 The purpose of this testimony is to present 13 information on the matter of quality assurance for the 14 South Texas Project, Units 1 & 2 including the portions 15 of the program implemented by Brown & Root and 16 Westinghouse. 17 Detailed information on this subject can be 18 found in Chapter 17 of the Preliminary Safety Analysis 19 Report for South Texas Project Units 1 & 2 and Chapter 20 17 of the RESAR-41 (Reference Safety Analysis Report). 21 This information may be summarized as follows: 22 HL&P, as Project Manager for the Project 23 Participants, has the responsibility for quality assur-24 ance during the design, procurement, fabrication,

1 construction and operation phases of the South Texas 2 Project. 3 HL&P is fully aware of the attention that 4 should be applied to quality assurance during all of 5 these phases of the South Texas Project. In order to 6 establish and maintain the high quality level required 7 for project activities, HL&P has developed and has 8 fully implemented a comprehensive Quality Assurance 9 Program. This program is documented in the Quality 10 Assurance Program Manual and the South Texas Project 11 Quality Assurance Plan. This Program was implemented 12 prior to the selection of the NSSS vendor and is 13 presently being utilized in all facets of the project. 14 This program requires, at a minimum, that the quality 15 assurance activities performed by HL&P and its prime 16 contractors, subcontractors, and vendors comply with 17 the NRC criteria established in 10 CFR 50, Appendix B, 18 "Quality Assurance Criteria for Nuclear Power Plants", 19 appropriate Regulatory Guides and industry standards. 20 The HL&P Quality Assurance Department was 21 established to provide for the effective control of all 22 quality activities related to the nuclear power plants, 23 including those performed by all contractors and sup-24 pliers. We have developed and implemented a detailed 1 indoctrination, training and continuing education 2 program to assure that all quality assurance personnel 3 are fully qualified to discharge the responsibilities 4 assigned to them. 5 As the Manager, Quality Assurance, I report 6 on all technical and administrative matters to the 7 Executive Vice President of HL&P. This reporting 8 arrangement provides independence for the quality 9 assurance function. 10 Our HL&P Quality Assurance personnel have the 11 duty and authority to identify quality problems; to 12 initiate, recommend or provide solutions; and to verify 13 the implementation and effectiveness of solutions. To 14 e n force this, they have authority to "Stop Work" in all 15 design, procurement, construction and operation phases 16 of HL&P nuclear power plant projects. 17 A Project Quality Assurance Manager is 18 assigned to the South Texas Project. He has the respon-19 sibility of implementing the South Texas Project Quality 20 Assurance Plan and deals directly with the HL&P Project 21 Manager, other line organizations, contractors and 22 subcontractors. In addition, HL&P will have on the site 23 qualified resident quality assurance personnel who will 24 perform continuous surveillance on all site activities; 1 t hese i ndivi du a l s r eport t o t he Pro j e c t Qualit y Assuran c e 2 Manager. 3 While HL&P retains overall responsibility for 4 the Quality Assurance Program, portions of the Program 5 are implemented by Brown & Root and Westinghouse. 6 Brown & Root and Westinghouse have developed 7 and implemented quality assurance programs that satisfy 8 the NRC regulatory requirements and those required by 9 HL&P. 10 Within the Brown & Root organization, a 11 Project QA Manager has been appointed to supervise the 12 site QA activities. He reports to the Brown & Root 13 Manager of Quality Assurance at Brown & Root headquarters 14 in Houston, who in turn, reports to the Senior Group 15 Vice President of the Power Division. At the Houston 16 office, a Project QA Engineer is responsible for quality 17 assurance during design and procurement and reports to 18 the Manager of Quality Assurance. Also, a Vendor 19 Surveillance Coordinator reporting to the Manager of 20 Quality Assurance is responsible for the vendor surveil-21 lance activities. 22 At Westinghouse, the Nuclear Energy System 23 (NES) Divisions are responsible for supplying the 24 Pressurized Water Reactor (PWR) nuclear steam supply - - - - - - . r - - - - - - - -- - - --*- 1 systems and compo nents for the South Texas Project. 2 Within NES, the PWR Sy s tems Division , headed b y a 3 General Manage r, is respon sible for design, procurement, 4 and quality assurance for all of the nuclear s ystems 5 and components. 6 The PWR Systems Division Product Assurance 7 Department is responsible for integrating and auditing 8 the quality-related work and the quality assurance 9 programs of the NES Divisions and the external suppliers 10 to Westinghouse. This Department is headed by the 11 Manager, Product Assurance, who reports directly to the 12 General Manager of the PWR Systems Division. 13 HL&P has conducted a comprehensive audit 14 program to verify that this overall QA Program as 15 described is indeed being implement ed in a satisfactory 16 manner. 17 In summary, a comprehensive quality assurance 18 program has been established and implemented for all 19 quality-related activities as described in Chapter 17 20 of the South Texas . Project PSAR. Implementation will 21 continue for the life of the Project, with reviews and 22 modifications to the program being made, as necessary, 23 to conform to new requirements as they may arise. 24 C i ! i:, i UY *\ R* SC: : : ., .1*t* 1 : 2 0 /.\ r

Re : Complia nce with A~penciix I . 1 My name is Walton A. Rodger. I am a partner in 2 the c onsulting firm of Nuclear Safety Associates. My 3 technical and professional qualifications have been 4 previously received in evidence. I have been continu-5 ously involved in the nuclear energy field since 1942. 6 Much of my professional career has been devoted to study 7 and consulting in the area of control of effluents from 8 nuclear facilities. 9 This statement addresses itself to the ques-10 tion whether the proposed nuclear facility, South Texas 11 Project Units 1 & 2, will discharge radioactive effluents 12 to air and water which will be "as low as practicable," 13 and whether the proposed facility meets the requirements 14 o :E Appendix I to 10 CFR 50, as adopted by the Nuclear 15 Regulatory Commission ("Commission") effective June 4, (1) (2) 16 1975 and amended.effective September 4, 1975. 17 Under Section I of Appendix I, design objec-18 tives conforming to the guidelines of Appendix I are 19 deemed to be a conclusive showing of compliance with the 20 i "as low ~s p~acticable" require~ents of 10 CFR 50.34a. 21 1 These guidelines are set forth in paragraphs A, B, C, 22 and D of Section II of Appendix I. This testimony will 23 Ishow that each unit of STP meets the design objectives 24 j of paragraphs !IA, IIB, and !IC.

1 Paragraph I ID of Ap pendi x I sets f or th a 2 cost-benefit analy s i s t hat mu s t be pe rf orme d t o ascer-3 tain whether additional items should be added to the 4 radwaste system. As amended by the Commission effec-5 tive September 4, 1975, however, parag raph IID provides 6 that such analysis need not be performed in the case 7 of an application docketed prior to June 4, 1976--such 8 as that for the South Texas Project--if the radwaste 9 systems satisfy the Guides on Design Objectives for 10 Light-Water-Cooled Nuclear Power Reactors proposed in 11 the Concluding Statement of Position of the Regulatory 12 Staff in Docket-RM-50-2 (hereinafter called the "Staff's 13 Concluding Statement") reproduced in the Annex to (3) 14 Appendix I. Applicant has presently chosen to comply 15 with paragraph IID by demonstrating that it satisfies 16 the Staff's Concluding Statement. Thus, this testi-17 mony will also show that the radwaste systems satisfy 18 paragraphs A, B, and C of the Annex to Appendix I. 19 I have made a completely independent analysis 20 of the South Texas Project radwaste systems using the 21 most recent versions of the Draft Regulatory Guides per-22 taining to Appendix I as follows: 23 I.AA Calculation of Annual Average Doses 24 to Man from Routine Releases of Reactor Effluents 1 for the Purposes of Implementing Appendix I, 2 September 23, 1975. 3 I.BB Calculation of Releases of Radioactive 4 Materials in Liquid and Gaseous Effluents from 5 PWR, September 9, 1975. 6 I.DD Methods for Estimating Atmospheric 7 Transport and Dispersion of Gaseous Effluents in 8 Routine Releases from Light Water Reactors, 9 September 22, 1975. 10 The results of my analyses are summarized in this 11 statement. 12 I. Description of Waste Systems 13 The waste systems to be used at the South 14 Texas Project have been described in some detail in 15 Chapter 11 of the Preliminary Safety Analysis 16 Report (PSAR). For an orderly presentation of this 17 testimony, a brief and simplified description of the 18 waste treatment systems proposed for handling the 19 gaseous and liquid wastes from STP follows. 20 A. Gaseous Systems 21 The South Texas Project reactors, in company 22 ith any Pressurized Water Reactor ("PWR"), can be ex-23 ected to have small but discernible releases of gaseous 24 astes from the following sources: 1 (1) Primar y Gas System 2 (2) Secondary Off-gas 3 (3) Steam Generator Blowdown Vent 4 (4) Containment Purging 5 (5) Ventilation of the Auxiliary Building 6 (6) Ventilation of the Turbine Building. 7 A brief discussion of each of the six 8 sources follows. 9 The primary coolent in a PWR, if the core 10 contains any significant fraction of failed fuel, 11 will contain some radioactive fission products some 12 of which are gases. At one or more points in the 13 system (in the case of South Texas Project at the 14 Volume Control Tank) some of these gaseous fission 15 products are drawn off and sent to the Primary Gas 16 System. This system in the South Texas Project con-17 sists of a compressor, cooler, moisture separator, 18 dryer (2 in parallel) and four charcoal-filled delay 19 tanks. The effective holdup time in the delay tanks 20 before discharge is about four days for kryptons and 21 more than 60 days for xenons. The purpose of the 22 holdup is to allow time for the shorter-lived corn-23 ponents of the waste gas to decay prior to release. 24 This significantly reduces the dose impact of the 1 discharge. 2 In PWR the primary coolant is used in a 3 steam generator to transfer heat to a secondary water 4 circuit in which steam is produced for use in the 5 turbine generator to produce electricity. So long as 6 there are no leaks in the tubes in the steam genera-7 tor, there will be no radioactivity associated with 8 the secondary system even if there is radioactivity 9 in the primary system. Thus the loss of radioactivity 10 from the secondary system of a PWR is a "second order" 11 probability, that is, there must be simultaneously 12 present significant failed fuel and significant steam 13 generator tube leakage to produce any significant loss 14 of radioactivity from the secondary system. In this 15 analysis allowance has been made for an assumed release 16 from the secondary system. 17 In most PWR the blowdown taken from the steam 18 generator to maintain proper water chemistry in the sys-19 tem is discharged into a blowdown tank where it is cooled 20 by allowing a portion of the liquid to flash (boil). The 21 off-gas from this tank has been shown to be a possibly 22 significant source of radioactivity, particularly 23 iodine, if discharged directly. At the South Texas 24 Project, however, the vapor from the blowdown tank is I 1 condensed in feed water heaters and all of the liquid 2 is returned to the condenser hotwell. This approach 3 eliminates this source of gaseous waste completely. 4 PWR are provided with containment shells. 5 There is a great deal of equipment inside these con-6 tainment shells and it contains the primary coolant 7 at elevated temperature and pressure. It is not pos-8 sible to maintain all of th is equipment in a com-9 pletely leak-free condition. Therefore, it is to be 10 expected that some of the primary coolent will escape 11 into the containment shell, and that some of the es-12 caped material will become and remain airborne. When 13 it is necessary to enter the containment shell for any 14 length of time, it is generally desirable to purge the 15 containment atmosphere in order to reduce the radio-16 activity in the air which will be breathed by the 17 personnel entering. When this is done the remaining 18 air-borne activity in the containment atmosphere will 19 be released to the environment. To reduce the amount 20 so released, the South Texas Project containment in-21 eludes two 10,000-cfm "kidneys", internal devices which 22 circulate the containment atmosphere through charcoal 23 and HEPA filters to reduce the iodine content. In the 24 calculation of emissions from containment, it has been 1 assumed that there wi l l be a continuou s purge of con-2 tainment at a rate o f 100 0-cfm, even though the plans for 3 operation do not include the use of conti n uous purge. 4 The Auxiliary Building of a PWR houses a good 5 deal of anciliary equipment used for the control of 6 radioactivity of the system and for man y other sub-7 systems needed for the operation of the reactor. Many of 8 these can be expected to leak small quantities of radio-9 active liquids into the building and some of these will 10 become airborne . Thus there is the possibility that some 11 radioactivity will escape with the ventilation air from 12 this building. At the South Texas Project the Auxiliary 13 Building ventilation air is released without treatment 14 prior to discharge. 15 Similarly, there is a possibility, albeit less 16 than in the case of the Auxiliary Building, that there 17 can be radioactive material in the air in the Turbine 18 Building. At the South Texas Project this ventilation 19 air is released without treatment. 20 B. Liguid sistems 21 Liquid wastes from PWR come from a variety 22 of sources which have a considerable disparity in chem-23 ical and radiochemical composition and concentration. 24 Normally these wastes are collected and treated I

1 separately. The liquid wastes from South Texas 2 Project fall into the following five categories: 3 (1) eves Waste - (Waste Portion of LWPS) 4 (2) Clean Waste - (Recycle Portion of LWPS) 5 (3) Floor Drains - (Waste Portion of LWPS) 6 (4) Chemical Waste - (Waste Portion of LWPS) 7 (5) Detergent Waste - (Waste Portion of LWPS) 8 A brief discussion of each of the five 9 categories follows: The eves System is set up to 10 control the concentration of boric acid in the primary 11 coolant. In a real sense it is not a waste system at 12 all but rather an integral part of the control system for 13 the reactor. However, a portion of the product needs 14 to be discarded to control the concentration of tritium 15 in the primary system; thus the system contributes 16 to the discharges of radioactivity in liquids and needs 17 to be considered as a waste system. 18 The eves System for the South Texas Project 19 consists of two ion exchangers (in parallel), two holdup 20 tanks, an evaporator, and a distillate ion ex-21 changer. A portion of the overhead distillate is sent 22 to the waste portion of the Liquid Waste Processing 23 System ("LWPS"), where it could, if necessary, be given, 24 further processing. Since further processing will .

-a-

~ : rrnally not be needed, in this analysis I have

I! ~ ::; sumed that this distill a te is released after 3 an alysis without further processing.

4 The Clean Waste (Recycle) System is set 5 up to handle reactor-grade water from equipment 6 and sample drains. These wastes are collected 7 separately in a Waste Holdup Tank and may be evaporated, 8 deionized, or both, or released without treatment as 9 circumstances dictate. 10 The Floor Drain System is set up to handle 11 the wastes which have been collected from the floor 12 sumps of all of the buildings save the Turbine 13 Building. These wastes tend to be more variable 14 in composition and lower in radioactivity than the 15 clean waste. Their treatment at the South Texas 16 Project consists of collection, evaporation, and/or 17 ion exchange, or they may be released without treat-18 ment if circumstances warrant. 19 The Chemical Waste System collects the 20 regenerant from the condensate cleanup system. This 21 waste, if contaminated due to steam generator tube 22 leakage in conjunction with significant failed fuel, 23 will require evaporation. 24 1 The overhead from evaporation can be further treated 2 with ion exchange if desired . . The evaporator overhead, 3 with or without further treatment, is released. The 4 evaporator bottoms are solidified and sent to a com-5 mercial burial ground. 6 Stearn generator blowdown from a PWR will not 7 contain any radioactivity unless there is sirnltaneous 8 steam generator tube leakage and a significant fraction 9 of failed fuel. At the South Texas Project steam 10 generator blowdown is returned to the condenser hotwell 11 and thence to the condensate dernineralizers. Thus in 12 a sense this waste stream does not exist at the South 13 Texas Project. 14 Detergent wastes come from the laundry, showers, 15 and decontamination operations. The activity level is 16 very low. The detergent content, on the other hand, very 17 much complicates the treatment of other wastes, were 18 these to be combined with them. Consequently it is 19 desirable to segregate this waste category and this is 20 done at the South Texas Project. The treatment provided 21 for this stream at the South Texas Project is normally 22 filtration, although additional treatment is available if 23 needed. In this analysis only filtration is assumed. 24 Turbine Building drains usually contain only 1 very low levels of radioactivity even if there is some 2 steam generator tube leakage. It is not generally the 3 practice to provide any treatment for this stream. In 4 our analysis, allowance has been made for the contribu-5 tion of this stream to total liquid discharges. II. Emissions of Radioactivity from the South Texas 6 Project 7 The emissions of radioisotopes from the 8 operation of the South Texas Project have been estimated 9 using techniques similar to those used by the Commission 10 Staff in making their analyses. My source terms were 11 developed using the same PWR-GALE code used by the Staff. 12 All such calculations are dependent, however, on a series 13 of assumptions and judgments. I believe that my assump-14 tions are essentially identical to those of the Staff 15 for the gaseous systems--so the resulting source terms 16 (shown in attached Table 1) should be almost identical. 17 The Project's liquid system is so flexible, however, that 18 no two analysts are likely to make precisely the same 19 assumptions. Thus there may be some small differences 20 between the liquid source terms I have calculated (shown 21 in attached Table 2) and those used by the Staff. 22 III. Calculation of Individual and Site Boundary Doses 23 The source terms from Tables 1 and 2 were con-24 verted into site boundary and "maximum individual" doses

1 using the equations give n in Draft Regulatory Guide 2 l.AA (September 23, 1975). Some of the calculations 3 were done by hand calculator, others by the use of 4 computer codes developed by Nuclear Safety Associates. 5 Site boundary calculations were done for the 6 north sector at a distance of 1430 meters. A number of 7 critical residences were checked--the controlling point 8 was taken as a residence located 4300 meters NNW of 9 the reactors. 10 In making these calculations it is necessary 11 to use values of atmospheric dispersion, X/Q, and 12 deposition, D/Q, at the points of interest. The ap-13 plicant's meteorological consultants, NUS Corporation, 14 reviewed the site meteorology as reported in the PSAR 15 and the Environmental Report in light of the new Draft 16 Reg. Guide l.DD (September 22, 1975). They provided the 17 meteorological parameters listed in attached Table 3 18 which I used in this analysis. 19 The calculated maximum doses to an individual 20 from liquid effluents are shown in attached Table 4. It 21 is obvious from Table 4 that the South Texas Project meets 22 with ease either the design objectives of paragraph IIA 23 of Appendix I or those of paragraph A.l of the Staff's 24 Concluding Statement. Further, Table 2 shows that South 1 Texas Project meets parag raph A.2 of the Sta ff's Con-2 c luding Statement. 3 The resulting site boundary air doses were 4 determined to be: 5 Single Unit Two Units 6 Gamma 0.013 mrad/yr 0.26 mrad/yr 7 Beta 0.26 mrad/yr 0.52 mrad/yr 8 Thus it is apparent that the Project also meets with ease 9 the design objectives for noble gas emissions contained 10 in paragraph II.B.l of Appendix I as well as paragraphs 11 B.l and B.2 of the Staff's Concluding Statement. 12 The calculated external doses from gaseous 13 effluents to real individuals, located at the above 14 ~efined residence, were determined to be: 15 One Unit Two Units 16 Total Body Dose 7.7E-03 mrem/yr l.5E-02 mrem/yr 17 Skin Dose 2.0E-02 mrem/yr 4.0E-02 mrem/yr 18 Here again these doses are much below the design objec-19 tives of paragraph II.B.2 of Appendix I or of paragraph 20 B.3 of the Staff's Concluding Statement. 21 The calculated doses from the emission of 22 iodines and particulates in effluents to the atmosphere 23 are shown in Table 5. The values shown in Table 5 are for 24 dose pathways which could reasonably exist, as required by I

1 Ap pe ndix I . These v a lues are for a s i ngle unit. Even 2 doubled to allow for t wo- unit operation at the s i t e , the 3 maximum individual total body dose is less than 1 mrem/yr 4 and the maximum indi v idual organ dose is less than 2 5 mrem/yr. Thus STP satisfies paragraph II.C of Appendix 1 6 and paragraph C.l of the Staff's Concluding Statement. 7 Table 1 shows that STP also satisfies paragraph C.2 of 8 the Staff's Concluding Statement. 9 The above calculated doses are summarized in 10 Table 6 and compared to the requirements of Appendix I 11 and the Staff's Concluding Statement. Again it is clear 12 that STP meets all pertinent requirements with ease. IV. Conservativeness of the Nuclear Regulatory Commission _ 13 Staff's "Upper Bound" Calculations 14 In an affidavit filed by Dr. Jacob Kastner for ( 4) 15 the Commission Staff earlier in this proceeding, an 16 "upper bound" calculation of the total annual population 17 dose resulting from the South Texas Project was presented 18 for purposes of demonstrating the unlikelihood that a 19 cost-benefit analysis pursuant to paragraph II. D of 20 Appendix I would require any addition to the radwaste 21 systems. In view of the Commission's subsequent revision 22 of paragraph II.D, as I have previously indicated, no 23 such cost-benefit analysis is presently required in this 24 case. However, it is clear that Dr. Kastner's analysis 1 was indeed a conservative "upper bound" calculation. 2 We are now in a position to make a more nearly 3 precise "upper bound" calculation. Attached Tables 4 4 and 5 show that the real individual subject to maximum 5 exposure may be expected to receive from the operation 6 of a single unit less than 1 mrem/year thyroid dose and 7 less than 0.5 mrem/year total body dose from liquids and 8 gases. 9 In general the average dose over fifty miles 10 is found to be about 1% of the maximum individual dose. 11 Therefore we can expect that the average doses over the 12 SO-mile radius will be about: 13 total body SE-03 mrem/yr 14 thyroid lE-02 mrem/yr 15 The projected year 2020 population for the 50-16 mile radius surrounding the Project site is about 17 800,000 persons. Therefore the total annual population 18 dose in 2020 from one South Texas Project unit can con-19 servatively be expected not to exceed: 20 total body 4 person-rem 21 thyroid 8 person-thyroid-rem. 22 Dr. Kastner's "upper bound" estimate, which was 23 based upon a total U.S. population, was about 24 total 24 body person-rem and 35 thyroid-person-rem. This clearly 1 conservati v ely over e stimat e d the annual p opul ation d o se 2 within 50 miles which would be considered if a cost-3 benefit analysis were being performed under paragraph 4 II.D of Appendix I. 5 V. Conclusion 6 My independent analysis of the South Texas 7 Project shows that the radwaste systems proposed by 8 the Applicant meet the design objectives of paragraphs 9 II.A, II.B, and II.C of Appendix I and that, since they 10 satisfy paragraphs A, B, and C of the Staff's Concluding 11 Statement, they also meet the objectives of paragraph 12 II.D of Appendix I. 13 14 15 16 17 18 19 20 21 22 23 24 l

Re: Occupational Exo a sures 1 My name is R . D. Ga un y . I am a Health Physi-2 cist in the Nucle ar Division of the Power Plant Engi-3 neering and Construction Dep artment of Houston Lighting 4 & Power Company. 5 A resume of my educational and professional 6 qualifications has previously been received in evidence. 7 It is my function in the South Texas Project to assure 8 that the facility is designed and operated in a manner 9 that assures that exposures are within regulatory 10 requirements. 11 At the earlier hearings in this proceeding, 12 the Board expressed interest in the occupational dose estimate included by the NRC staff in the Final Environ-13 mental Statement for the South Texas Project. The FES 14 assumed that the occupational dose associated with the 15 South Texas Project plant would be 450 man-rem per year 16 per unit. This, of course, is only an estimate based 17 upon experience at other nuclear power plants. Speci-18 fically, it is derived from WASH-1311, "A Compilation 19 of Occupational Radiation Exposure from Light Water 20 Cooled Nuclear Power Plants, 1969-1973." . 21 The matter of occupational exposures is dealt 22 with in detail in the Preliminary Safety Analysis 23 Report for the South Texas Project, specifically in 24

1 Section 12. 1. 6 and Tables 1 2 .1 -24 t hrough 1 2 .1- 30. 2 At t he out set , I would l ike to state that the 3 450 man-rem per unit figure (whi ch i n cl ude s e x posures 4 to both permanent operating personn e l and support 5 maintenance people) is neither a g oal nor a design 6 objective for the Project. It will be our objective to 7 reduce occupational exposures to a level as low as 8 reasonably achievable and, in fact, we would expect to 9 maintain in-plant exposures significantly lower than 10 those estimated by the Staff. Our management is com-11 mitted to this goal in the manner required by paragraph 12 C.l. of Regulatory Guide 8.8 on "Occupational Radiation 13 Exposures at Nuclear Reactors." 14 In implementation of our management commitment, 15 we are taking steps in the design of the facility and 16 will adopt work practices to help us achieve our goal 17 of minimizing radiation exposures to onsite personnel, 18 whether permanent or transient. 19 Turning first to the matter of design, the 20 South Texas Project facility will incorporate features 21 which should be extremely helpful in reducing occupa-22 tional exposures. Among the specific features designed 23 to reduce exposures are permanently installed scaffolding 24 around the steam generator, and a design that allows 1 for removal of the steam generator in one piece. The 2 use of volatile chemistry in the treatment of the 3 secondary side of the steam generator has also been 4 selected in an effort to reduce exposures. The use of 5 remote welding techniques and explosive plugs are being 6 considered to further reduce exposures during steam 7 generator maintenance. As the Board is aware, the 8 surveillance and maintenance of steam generator tubes 9 has proven to be a major contributor to occupational 10 exposures. It is our expectation that the South Texas 11 Project design features will reduce substantially the 12 dose associated with such operations. 13 The overriding design criterion for the 14 facility shielding, equipment, and layout has been to 15 keep radiation exposure to operating personnel as low 16 as reasonably achievable (ALARA) and well within the limits of 10 CFR 20. The facility is being designed in 17 conformance with the reconunendations of Regulatory 18 Guide 8.8, which suggest ways in which ALARA exposures 19 can be achieved (such as careful selection and placement 20 of equipment, isolation of that equipment from personnel 21 as much as possible, and reducing frequency and duration 22 of equipment maintenance periods). A few examples of 23 how this has been achieved in the design of the South 24 1 Texas Project, Units No . 1 and 2 follow. 2 The Mechanical and Electrical Auxiliary 3 Building where facility radioactive waste is collected, 4 processed, and prepared for disposal, has been arranged 5 with a large part of the middle level exclusively 6 devoted to the routing of pipes containing radioactive 7 fluids. This radioactive pipe chase is connected with 8 all of the shielded enclosures that are provided for 9 equipment containing radioactivity. In this way the 10 facility has been designed so that personnel will 11 always be shielded from radioactive piping and equipment 12 during routine operations. 13 Valve manipulation is accomplished in radio-14 active systems via remote reach rods or with powered 15 valve operators. Furthermore, the valves are isolated 16 from the system components that they serve. By careful 17 design, personnel.will not normally be exposed to un-18 shielded radioactive valves or pipes. When maintenance is required on these valves, the worker will be shielded 19 from the pump, tank or other radioactive system component. 20 Each radioactive system component is similarly isolated 21 from neighboring equipment so that maintenance can be 22 accomplished with minimal radiation exposure to personnel 23 and without shutdown of that system. 24

~4-

1 Each radioactive filter in the facility is 2 individually shielded and these filters are clustered 3 in one part of the Mechanical and Electrical Auxiliary 4 Building. Filter cartridge replacement has been care-5 fully planned so that rapid and safe accomplishment is 6 assured. Shielded cartridge transfer casks will provide 7 efficient delivery to the drumming area with minimum 8 personnel exposure. 9 Shielding and isolation are provided for 10 systems containing low levels of radioactivity. Some 11 examples of this are the Laundry and Hot Shower Tank 12 and associated components and the Spent Fuel Pool 13 Cooling and Purification System. 14 The residual heat removal (RHR) system com-15 ponents and piping are all either located behind the 16 Reactor Containment Building (RCB) secondary shield or 17 are individually iocated in shielded cubicles. This 18 allows safe access for personnel into the RCB shortly 19 after shutdown of the reactor and while the RHR system 20 is cooling the reactor down. Another important source of occupational ex-21 posures is that received during refueling operations. 22 It is our expectation that the Westinghouse rapid 23 refueling features incorporated in the South Texas 24 1 Project design will result in decreased radiation 2 exposures. Westinghouse has informed us that this 3 feature may reduce total exposures during such operations 4 by as much as a factor of 4. 5 These are but a few of the many features that 6 will keep occupational exposures as low as reasonably 7 achievable. The design of the facility has been and is 8 being monitored by competent radiation protection 9 specialists to ensure that this goal will be achieved. 10 We are taking other important design measures 11 to minimize occupational exposures. We require our 12 architect-engineer radiation protection specialists to 13 review the plant design to assure that it is consistent 14 with our occupational dose objectives. The architect-15 engineer must demonstrate to us that criteria intended 16 to reduce radiation exposures are incorporated in the 17 design. In genera"!, we are using the design guidance 18 set forth in Regulatory Guide 8.8. In addition, we 19 have established a systematic method to review abnormal 20 occurrences at other reactors so that this experience 21 can be factored into our design thereby minimizing the 22 possibility of unscheduled maintenance. Turning now to work practices and procedures, 23 the South Texas Project is committed to the development 24 1 of practices in plant operation to minimize occupational 2 radiation exposures. These practices will be incorpo-3 rated in the plant radiation manual and will be revised 4 to reflect operating experience. Among the practices 5 to be followed are such important measures as draining 6 and flushing components before maintenance, pre-job 7 training and planning, proper supervision of maintenance 8 personnel, and the transfer of components under repair 9 to areas with lower radiation fields. In the area of 10 administrative devices to reduce exposures, we expect 11 to make extensive use of personnel training measures, 12 including the use of mock-ups as required to familiarize 13 maintenance employees with the environment in which 14 they will work. We believe that by so doing exposures 15 during maintenance can be significantly reduced. Again 16 our plans and procedures for plant operation will be 17 developed in accordance with the recommendations of 18 Regulatory Guide 8.8. 19 At our earlier hearings, the Board questioned whether the assumption of 450 man-rems per year per 20 unit, as stated in the FES, was compatible with the 21 individual limits on radiation exposures in 10 CFR 20. 22 As noted above, the 450 man-rem figure employed by the 23 staff includes exposures to regular plant personnel as 24 1 we ll as to support maintenance personnel (i.e. t hose 2 maintenance personnel not permanently assigned to the 3 plant). Thus, there is no necessary inconsistency 4 between the 450 man-rem figure and the requirements of 5 10 CFR Part 20 with respect to individual exposures. 6 In any event, as noted above, 450 man-rem is neither a 7 goal nor design objective for the South Texas Project. 8 Present estimates of occupational exposures, excluding 9 support maintenance personnel, are in the range of 10 104.4 man-rem per unit per year to plant personnel 11 during routine operation and maintenance. We believe 12 that the steps outlined above provide a basis for the 13 expectation that occupational doses for the South Texas 14 Project will be substantially lower than 450 man-rem 15 !per year per unit, even including non-routine maintenance. 16 IIn any event, steps will be taken to assure that occu-17 lpational exposures of individuals are within the regu-18 latory requirements of 10 CFR 20. 19 In summary, the Applicant's commitment to 20 , minimizing occupational exposures is evidenced through-i 1 21 out the plant design and will also be reflected in our 22 operational practices and procedures. 23 24 2 0 3* pr ope ra~ t 2st i no nv? 4 A 6 Power Company. 7 A r esume of my educational and professi0n Al 8 qu a lific a ti on s h 1s been previously receiv,~d in evidence . 0 9 At earlier hearings in this proceeding the 10 Board expressed inter est in th e 4SO man -r em pe r year I I per unit occurotional dose esti ma te inclu rled by the 12 NRC Staff in t he Final Environmental Statement for th e 13 South Texas Pr oje ct. 14 450 ~an-rem per unit per year is neith e r a 15 goal nor a desiqn objective for the Project. 16 It will be our objective to re rlu ce 17 occupationAl exposures to a level as low as reason ab ly 18 achievable and, in fact, we would expect to ~aintain in-19 plant exposures much lower than those estimated by the 20 Staff. 21 In the matter of design, we have incorporated 22 numerous features which should reduce occupational 23 exposure. These include improvements in steam qenerator 24 access, considerations of remote welding techniques and 25 explosive plugs, careful selection and placement of

TESTIMONY OF RICHARD J . KLAPPE R Re: Interface Betwee n South Texas Project and RESAR-41 1 My name is Richard J. Klapper. My position 2 is Supervising Engineer, Nuclear Safeguards and Licensing 3 with Houston Lighting & Power Company. 4 A resume of my educational and professional 5 qualifications has previously been received in evidence. 6 My functions in connection with the South 7 Texas Project are to assure that the design, construc-8 tion and operation of the Project are in conformity 9 with all applicable NRC regulations and criteria. 10 The purpose of this testimony is to present 11 information on the matter of the safety-related inter-12 faces between the nuclear steam supply system and the 13 balance of the nuclear power plant. 14 Detailed information on this subject can be 15 found in Section 1.1.2 of the Preliminary Safety Anal-16 ysis Report for the South Texas Project Units 1 and 2 17 and on the blue pages in RESAR-41. 18 A design interface is a broad term generally 19 used to refer to a requirement established to assure that two related systems will be constructed and ope-20 ated in an appropriate and compatible fashion. The 21 NSSS supplier provides a great deal of information to 22 the utility, including a large number of specified 23 interfaces, in order to assure that the architect-24

1 engineer, the constructor and the utility will properly 2 design the balance of the plant (BOP) taking into ac-3 count the characteristics of the NSSS which affect the 4 BOP. In the case of the South Texas Project, this 5 extensive information was provided by Westinghouse as 6 paYt of a scandard design information package. 7 For regulatory purposes, it is necessary that 8 an Applicant for a standard design identify and designate 9 in its submittals to the NRC those safety-related 10 design interfaces that will assure compatibility between 11 the standard design and the BOP. 12 In the case of the South Texas Project, the 13 process of identifying and designuting such safety-14 related interfaces corrunenced in the RESAR-41 submitted 15 by Westinghouse pursuant to the provisions or Appendix 16 0 of 10 CFR Part 50. Section 3 of Appendix O requires 17 that a standard design submitted for NRC approval 18 include a description, analysis and evaluation of the 19 interfaces between the submitted design and Lhe balanc~ 20 of the nuclear power plant. 21 When the South Texas Project application was 22 docketed, the NRC Staff had not completed its detailed 23 review of RESAR-41, including its review of the portion 24 thereof that identifies safety-related interfaces. It 1 thus became important to assur e t hat comp le t i o n of NRC 2 Staff review of the interfaces appl ica ble to the Sout h 3 Texas Project units would not be delay ed by the more 4 comprehensive review required for issuance of a Pre-s liminary Design Approval (under Appendix 0) that would 6 be applicable to all future plants that might wish to 7 incorporate RESAR-41 by reference. 8 Accordingly a program was undertaken by 9 Westinghouse and HL&P to identify and designate on a 10 timely basis all of the safety-related RESAR-41 inter-11 faces necessary for purposes of the STP units. This 12 specific effort included a systematic evaluation by 13 Westinghouse of all information provided as part of the 14 standard/information package and to define additional 15 interface information to be included in RESAR-41. Such 16 information was incorporated into Amendment 17 of 17 RESAR-41 submitted in June, 1975. The NRC Staff iden-18 tified those aspects of the South Texas Project units 19 involving RESAR-41 interfaces that had to be resolved 2o for the specific purposes of the South Texas Project 21 docket prior to the issuance of the construction permit. 22 The NRC Staff issued three sets of questions to Houston 23 Lighting & Power Company on RESAR-41 interfaces and 24 these matters were satisfactorily resolved through 1 amendments to the STP PSAR submitted on August 15, 2 October 1, October 9, and October 27, 1975. Thus, the 3 combination of amendments to RESAR-41 and amendments to 4 the South Texas Project PSAR incorporating information 5 specifically applicable to the Project have provided 6 the necessary identification of the safety-related 7 interfaces. 8 The NRC Staff is continuing its review of 9 RESAR-41 for the purpose of issuing a PDA that will 10 enable future utility applicants to reference RESAR-41 11 without further review. This process, which is aimed 12 at a final, generic approval of RESAR-41 as a reference 13 design will continue. In the interim, those aspects of 14 the design requiring 1:esolution prior to the issuance 15 of the construction permit for the South Texas Project 16 have been resolved to the satisfaction of the NRC 17 Staff. 18 19 20 21 22 23 24 i ,:, j 0 3 .

TESTIMONY OF D. R. BLTTERTON Re: S ite Mon i toring Systems 1 My name is D. R. Betterto n. My position is 2 Manager, Environmental Protection Department with 3 Houston Lighting & Power Company. 4 A resume of my educational and professional 5 qualifications has previously been received in evidence. 6 My functions in connection with the South 7 Texas Project include managerial responsibility for the 8 conduct of a wide variety of studies relating to the 9 suitability of the South Texas Project Site including, 10 but not limited to geological and seismological investi-11 gations. I participated in the development of the 12 monitoring programs at the site which are discussed in 13 this testimony. 14 The purpose of this testimony is to present 15 information on the monitoring progra~ established to 16 measure the settlement of facility structures and to 17 measure regional ground surface subsidence. 18 Detailed information on this subject will be 19 found in the Preliminary Safety Analysis Report for 20 South Texas Project Units 1 and 2, specifically in 21 Section 2.5.4.13 at pages 2 . 5-157 through 2.5-157f. 22 This information may be summarized as follows: 23 A comprehensive site performance monitoring 24 program will be established to measure the settlement

1 of facility structures and to measure regional ground 2 surface subsidence. The monitoring programs are designed 3 to enhance the safety of the project by giving advance 4 warning of any unforeseen occurrences and to provide s basic data for verification of predicted plant founda-6 tion performance. The settlement portion of the monitor-7 ing program will consist of an array of borehole heave a points, extensometers, open standpipe piezometers, pore 9 pressure cells, and structural benchmarks. The regional 10 ground surface subsidence monitoring program will 11 consist of an array of shallow and deep aquifer open 12 standpipe piezometers, a network of vertical and hori-13 zontal ground control benchmarks, and a deep-reference 14 benchmark with continuous subsidence monitoring 15 instrumentation. 16 The settlement monitoring program will be 17 capable of monitor{ng heave and settlement of individual 18 soil layers during construction as well as the actual 19 settlement of facility structures. This will be accom-20 plished by the installation of twenty conventional 21 downhole monuments that are capable of measuring heave 22 of individual soil layers. Fourteen Sonde extenso-23 meters will also be installed to depths of 230 feet and 24 300 feet below the ground surface. The Sonde extenso-1 meters consist of corrugated plastic tubing with gauging 2 points fixed at selected increments. The flexible 3 nature of the Sonde tubing allows the gauging points to 4 move vertically as the subsoil heaves and settles 5 during construction activities and allows an accurate 6 determination of the deformation of individual soil 7 layers throughout the extent of the installation. In 8 excess of one hundred structural benchmarks will be in-9 stalled on plant structures as plant foundation and 10 substructure construction proceeds. These benchmarks 11 will be measured on a periodic basis to determine the 12 vertical movement of individual structures and Category 13 I piping systems. 14 In addition to the conventional downhole 15 monument, extensometer, and structural benchmark installa-16 tions, a piezometer field will be installed to monitor 17 shallow aquifer ground water in the construction area. 18 The piezometer field will utilize an initial installa-19 tion of open standpipe piezometers that are capable of 20 measuring the piezometric head in individual soil 21 layers. Certain piezometers within the excavation will 22 be located adjacent to extensometer and conventional 23 downhole monument installations in areas beneath plant 24 structures. In order to permit continued monitoring of 1 these piezometers during plant construction, pore 2 pressure cells will be installed in selected piezometers 3 and subsequently monitored remotely at a terminal box 4 at finished site grade. In addition, a number of pore 5 pressure cells will be installed directly in the struc-6 tural backfill to monitor the ground water in this 7 material. The piezometer and pore pressure cell instal-8 lations will be used to monitor the effectiveness of 9 the dewatering system and the ground water measurements 10 will be used to evaluate the effects of dewatering on 11 subsoil deformations during construction. 12 The regional subsidence monitoring program will be capable of monitoring both vertical and hori-13 14 zontal ground surface movements at the South Texas 15 Project site. This will be accomplished in part by the 16 installation of a deep-reference benchmark that is 17 designed to continuously measure total subsidence at the South Texas Project site throughout the life of the 18 plant. The deep-reference benchmark will be positively 19 20 anchored to the strata, below the potential subsidence zone (approximately 1155 feet below ground surface) and 21 separated from the possible consolidation effects of 22 the overlying compressible zones by a 4-inch casing. 23 To provide continuous ground surface subsidence measure-24 1 ments a modified Stev ens Ty pe F Recorde r will be i nsta l l e d 2 and operated within an Instrument Shelter. The deep-3 reference benchmark design is similar to the United 4 States Geological Survey deep benchmarks currently in 5 operation in the Houston area. 6 The deep-reference benchmark will be installed 7 prior to the commencement of dewatering and will be 8 used to establish baseline vertical datum control for 9 both the settlement and regional monitoring programs. 10 The deep reference benchmark will be referenced to the 11 National Geodetic Survey (NGS) benchmarks in Bay City, 12 Texas, in order to correlate site specific data with 13 other subsidence readings in the area. This will be 14 done whenever the NGS makes its own level loops. 15 Twelve near-surface monuments capable of 16 measuring vertical ground surface movement will be in-17 stalled in the plant vicinity at a depth (approximately 18 15 feet) sufficient to minimize seasonal shrink-swell 19 ground surface movements due to variations in water 20 content in the surface clays. The near-surface monuments 21 will be referenced on a periodic basis to the deep-22 reference benchmark. 23 Eight near-surface monuments will be installed 24 in the plant vicinity to measure horizontal movement at 1 the ground surface. These monuments will also be 2 designed to minimize seasonal shrink-swell ground sur-3 face movements. The horizontal positions of these 4 monuments will be referenced to the NGS Texas Plane Co-s ordinate System. 6 To supplement the vertical and horizontal 7 near-surface monuments an array of open standpipe 8 piezometers will be utilized to monitor the two distinct 9 groundwater aquifer zones. Ten deep-aquifer piezometers 10 have been installed and are currently being monitored 11 on a weekly basis. One additional deep aquifer piezometer 12 will be installed adjacent to the deep reference bench-13 mark so that variations in ground water level can be 14 directly related to the regional subsidence monitoring 15 data. In addition to the field of piezometers and pore 16 pressure cells installed in the plant area to monitor 17 dewatering in the shallow aquifer zone, twenty open 18 standpipe piezometers will monitor the shallow aquifer 19 zone at various locations throughout the South Texas 20 Project site area. Data from deep and shallow piezo-21 meters will be used to evaluate the Project's regional 22 subsidence model. As regional subsidence results from 23 piezometric decline and is time dependent, the data 24 from the piezometer monitoring system will serve as an 1 advance warning of any unforeseen occurrence and will 2 provide a data base to verify the regional subsidence 3 model. 4 All the subsidence and settlement measurements 5 on deep and near-surface monuments and structural 6 benchmarks will be taken by Houston Lighting & Power 7 Company personnel or their appointed representatives. 8 This program will permit observations within the plant 9 site area to record elevation differences of 0.010 ft. 10 and horizontal movements at an accuracy of 1:10,000. 11 In summary, a site performance monitoring 12 system will be implemented to detect changes in ground 13 water levels across the Project site and to measure 14 changes in vertical elevation in and around the Category 15 I Structures. The vertical monitoring system will be 16 referenced to both a deep-reference benchmark on the 17 site and by periodic level to the NGS's first-order 18 loop in Bay City, Texas. Horizontal measurements 19 between selected monuments will also be accomplished on 20 a periodic basis and referenced to the NGS Texas Plane 21 Co-ordinate System. The level of accuracy of the 22 measurements will be such that changes significantly 23 smaller than the design limits can be observed and 24 evaluated prior to the time that the limits would be 1 exceeded. 2 Results of the monitoring and related studies 3 will give advance warning of any unforeseen occurrences 4 and will provide data in support of predicted plant 5 foundation performance. The Applicant has committed to 6 advise the Nuclear Regulatory Commission should measured 7 performance approach the design criteria limits during 8 the life of the plant. 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

" 14 Would you please respond to that q u es tion? 15 I A. Yes, sir. 16 South Texas Project is well aware of the impo rtance 17 of insuring that adequate steam generator tube integrity is 18 maintained under all conditions of operation. In light of 19 current nuclear operating experience, the steam generators for 20 the South Texas Project, Unites 1 and 2, will be operated with 21 all volatile treatment. That is AVT, secondary water 22 chemistry, and will follow the Westinghouse AVT chemistry 23 control specifications. All volatile treatment uses volatile 24 means for control of water chemistry rather than a combined /o *ederal Reporters , Inc . 25 phosphate and sodium treatment.

                                                                                                                 ,; 3 J.

The results of pro pe r impl eme ntation of a ll volatile chemistri e s control are to,           (a) , minimize me tal corro s ion,   (b)  limit accumulation of sludge in the st eam generator,     (c), to minimize hardness scale for mation on heat transfer surfaces,       (d), minimize the potenti a l for formation 11    i of precaustic ~r acid, and (e), to maintain low oxyge n con-i I

Cook Unit 1, have employed llVT water secondary 19 treatment. 20 Other plants have operated successfully for longer 21 time periods using AVT chemistry control . .

Yes, sir. 7 After reports of the Brown's Ferry incident on 8 page 22D, 1975, Federal evaluation of the South Texas Projec t 9 design was initiated to establish the likelihood and possib le I 1o I consequences of a similar incident at South Texas. From the 11 evaluation two conclusions are reached. 12 First, there is little likelihood of a similar 13 incident at South Texas because of the adherence to updated 14 regulatory guides, and IEEE standards adopted since Brown's 15 Ferry 1 and 2 received their construction permit in 1966. 16 As an example of that, the South Texas Project cable qualified 17 to IEEE 383 of 1974, but passed stringent flame tests and non-18 combustible or self-extinguishing flame retardant sealing 19 material will be used. 20 Secondly, if a cable fire were to occur in a 21 cable spreading room at the South Texas Project, the con-22 sequences would not be as serious as at Brown's Ferry because 23 of the following: (a), the physical separation between Units 24 1 and 2; (b), the independence of safety-related systems; /' - ederal Reporters, Inc . 25 (c), the adherhence to regularory guides on ca~le materials

S. Nuclear Regulatory Commission. I am responsible for the e.valuation of nuclear safety aspects of nuclear reactor facilities and serve as the project manager for technical evalua-tion of nuclear power reactor license applications. I attended the University of Nebraska where I majored in Electrical Engineering and participated in the Navy Regular ROTC program. I graduated with a Bachelor of Science degree and was commissioned as a regular officer in the United States Navy in JW1e, 1965. Additional graduate level studies in nuclear reactor theory, health physics and related engineering fields were completed in 1966 at the Officer Naval Nuclear Power School, Mare Island, California. I subsequently studied and qualified as an operator and supervisor at the Naval Reactors nuclear power facility in West Milton, New York. My association with the Naval Nuclear Propulsion program provided me -j with five years of professional experience in the nuclear field, primarily with pressurized water re~ctors. I have been qualified as a Senior Reactor Operator on three Navy nuclear propulsion plants. For two years I was assigned to an operating nuclear submarine, during which time my dµties included directing, training and supervising technicians in the operation, maintenance and repair of various equipment and systems, including the

My duties included s up er vi sing t he Electrical Division and the Reactor Control Division, testing of the nuclear propulsion plant, directing and supervising technicians in the inspection, testing and operation of various equipment and systems, and training of technicians for examination and qualification as reactor operators and various other operating positions. In 1970 I was assigned as an instructor in advanced tactics at the Officers Submarine School where I instructed and trained crews of nuclear submarines. I joined the Regulatory staff of the Atomic Energy Corrunission September, 1972 as a reactor engineer. Since then I have participated as an Environ-mental Project . Manager in the analysis and evaluation of the environmental features of design of the Dresden Units 2 and 3 facilities. As a Project Manager in operating reactors, I participated in the review and evaluation of safety considerations associated with the design and operation of several licensed power reactors. Subsequently, I have participated in the analysis and evaluation of engineering safety features of design of power reactors under license application review. I have been particularly closely j associated with the reviews of the Westinghouse Electric Corporation's Reference Safety Analysis Report, RESAR-41, and Boston Edison Company's Pilgrim Nuclear Generating Station, Unit 2, and the preapplication review of South Car~lina Electric and Gas Company's Virgil C. Summer.Nuclear Station Unit 2.

HARVIN S . DUNENFELD PROFESS IOi.li\L QUALIFICATIONS My name is Marvin S. Dun enf eld. I am a Reactor Physic ist in the Core Performance Branch within the Directorate of Lice nsing . As a Reactor Physicist, I share with other members of the Branch the responsibility for technical review of reactor physics safety aspects of li ght water cooled power reactors for Construction Permits and Operating Licenses. I was born in Newark, New Jersey, on December 31, 1926. I attended public schools in Flushing, New York, and entered Queens College in Flushing, New York, in 1944. I transferred to the University of Michigan in 1945, graduating with a Bachelor of Science degree (physics major) in 1951 and a Master of Arts in mathematics in 1953. I was employed by the Ford, Motor Company in Ypsilanti, Michi gan, from 1953 to 1957 as an Electrical Product Project Engineer. I joined the nuclear industry in 1957 in a position at the Atomics International divi-sion of North American Rockwell Corp. in Los Angeles, California. I was employed there for about two years in reactor shielding and then four years as a physicist in reactor kinetics. In the latter capacity, I participated in research and analysis of reactor transients on the kinetics experiment on water boilers. In 1963 I accepted employment as a nuclear physicist with the Allison Division of General Motors in Indianapolis, Indiana. I was responsible for safety analysis on the Military Compact Reactor Project, and later per-formed reactor physics and safety analyses on other reactor concepts.

In 1967 I joined the Division of Reactor Licensing, U. S. Atomic Energy Commission. My responsibilities with the Conunission have been in the technical evaluation of physics related safety aspects of light water reactors. I have participated in the evalua tion of all the PWR Operating Licenses Regulatory has reviewed since 1967, about half of the PWR Construction Permits, and a few of the BWR applications. I have also directed the efforts of the four physics consultants to Regulatory at Brookhaven National Laboratory since the inception of this activity in 1967. l'!l'* * - 1'

Int rod uctio n On July 18, 1975, the NRC Staff (Staff) submitted to the Atomic Safety and Licensing Board affidavits of Messrs. J. Long and J. Boegli and I

   *i I Dr. J. Kastner. Those affid ~vits were filed in response to the Board's conference call of July 9, 1975 concerning the impl eme ntation of Appendi x I I                                                          .

of 10 CFR Part 50 adopted by the Commission on May 5, 1975, with reg a rd J to South Texas Project, Units 1 and 2. The affidavits indicated that the Staff was in the process of reassessing the parameters and mathemati cal models and that a detailed assessment to determine conformance with Appendix I would be compl~ted in connection with the hearing on radio-logical safety aspects of the facility. The purpose of this testimony is to present the results of that detailed assessment. The assessment was performed to determine if the proposed South Texas Project, Units 1 and 2 met the numerical design objectives specified in Sections IIA, B, C and D of Appendix I of 10 CFR Part 50. On September 4, 1975 (F.R. 172), the Commission amended Appendix I of 10 CFR Part 50 to provide persons who have filed applications for con-struction pennits for light-water-cooled nuclear power reactors which

February 20, 1974. As indicated in the Statement of Considerat ions included with the amendment, the Commiss ion noted it is unli kely that further reductions to radioac tive material releases would be warra nted on a cost-bene fi t basis for light-water-cooled nuclear power reactors having radwaste systems and equipment deten~ined to . be acceptable under the proposed Staff desiqn objectives set forth in RM-50-2. In a letter to the Commission dated October 1, 1975, Houston Lighting and Power Company chose to comply with the Commission's September 4, 1975 amendment to Appendix I, eliminating the necessity to perform a cost-benefit analysis as required by Paragraph II.D of Appendix I. Evaluation The Staff has evaluated the radioactive waste management systems pro-posed for South Texas Project, Units 1 and 2, to reduce the quantities of radioactive materials re*leased to the environment in liquid and gaseous effluents~ These systems have been previously described in Sections 11 .2 and 11.3 of the Safety Evaluation Report, dated August 1975, and in Section 3.5 of the Final Environm~ntal Statement (FES), dated March 1975. 1 Based on information provided by the applicant in the referenced letter, 1 I on more recent operating.data applicable to the South Texas Project, and i 1

 )    on changes in our calculational model, we have generated new liquid and I

gaseous source terms to determine conformance with Appendix I. These values

are different from those given in Tab l es 3.6 and 3. 7 of the FES for Units 1 and 2 and in Table l of Mr. Bo egli's affidavit (Ju ly 18, 1975). The new source terms, shown ih Attachments 1 and 2, were calculated using j the models and methodology described in Draft Regulatory Guide 1 . BB, i "Calculation of Releases of Radioactive Materials in Liquid and Gaseous

 ,I
  !l                          Effluents from Pressurized Water Reactors (PWRs),"                               September 9, 1975.

j These source terms were used to calculate the doses as described in l I testimony submitted by Mr. Waterfield. Attachment 3 provides a comparison of the calculated doses, with the design objectives of Sections IIA, Band C of Appendix I and the pro-posed Staff desian objectives set forth in RM-50-2. Based on the Staff's evaluation of the liquid radwaste management systems, the expected quantity of radioactive materials released in liquid effluents from Units 1 and 2 will be less than 5 Ci/yr/reactor, excluding tritium and dissolved gases, as shown in Attachment 2. The liquid effluents released from Units 1 and 2 will not result in an annual dose I or dose commitment to the total body or to any organ of an individual, i I l in an unrestricted area from all pathways of exposure, in excess of 5 mrem. i Based on the Staff's evaluation of the gaseous radwaste management systems, the total quantity of radioactive material~ released in gaseous I .i .I f

effluents from Uni t s 1 and 2 will not result in an annual gan~a air dose in excess of 10 mrads and a beta air dose in excess of 20 mrads at every location near ground level, at or beyond the site boundary, which could be occupied by individuals (Attachment 3). The annual total quantity of iodine-131 released in gaseous effluents will be~less than l Ci/reactor l (Attachment l) and the annual total quantity of radioiodine and radioactive

 ~l particulates released in gaseous effluents from Units 1 and 2 will not i

result in an annual dose or dose commitment to any organ of an individual l in an unrestricted area from all pathways of exposure in ~xcess of 15 mrem 1 .I (Attachment 3). j Conclusion Staff testimony demonstrates that the doses *associated with the normal j operation of South Texas Project, Units l and 2 meet the design l objectives of Sections II.A, II.Band II.C of Appendix I of 10 CFR Part 50, and that the expected quantity of radioactive materials released in liquid and gaseous effluents and the aggregate doses meet the design objectives set forth in RM-50-2.

l l

J 1 Staff's evaluation shows that the applicant's proposed design of Units 1 and 2 satisfies the criteria specified in the option provided by the Commis-sion's September 4, 1975 amendment to Appendix I and, therefore, meets the requirements of Section 11.D of Appendix I of 10 CFR Part 50.

Based on the Staff's eva lu ation the propos2d liquid and gaseous radwaste management systems for South Te xa s, Units l and 2 meet the criteria given in Appendix i and are therefore acceptable.

AFFIDAVIT OF ROBERT L. WATERFIELD RELATIVE TO AN APPENDIX I DOSE EVALUATION OF SOUTH TEXAS PROJECT UNITS 1 AND 2 Introduction In an affidavit(l) filed in the site-suitability yhase of this proceeding Dr. Jacob Kastner indicated that a detailed 8Ssessment of maximum individual doses would be completed in connection with the radiological health and safety hearing after completion of our reassessment of assumptions and models. The purpose of this testimony is to present the results of that detailed assessment. The assessment was performed to determine if the proposed South Texas Project facilities met the design objective contained in the Concluding Statement of Position of the Regulatory Staff, Docket 2 No. RM-50-2 (February 20, 19,74), ( ) and in 10 CFR 50, Appendix I (May 5, 1975). (3) 4 In a letter dated October 1, 1975, ( ) the Houston Lighting and Power Company indicated that it wished to exercise the option provided by the (5) . . Commission's September 4, 1975 amendment to Section II.D of Appendix I. The amendment provides that an applicant nee.cl not comply with the radwaste system cost-benefit analysis required by Section II.D of Appendix I if the proposed radwaste system satisfies the Guides on Design Objectives contained in the Concluding Statement of Position of the Regulatory Staff (Docket No. RM-50-2), dated February 20, 1974. ( 2 )

Si nce the Guides on Design Objectives apply to all light - water*-cool ed r eac t or s at a s it e , it was nec es sa r y t o compa r e the total dose f r om South Texas Units 1 and 2 with the Design Obj ectives cont a ined in the Conclud i ng Stat ement of Position of the Regulatory Staff. (Z) Discussion The dose models used to perform this analysis are contained in Draft Regulatory Guide l.AA. ( 6 ) These models were revised (with respect to the models contained in reference 1) to be responsive to the mandate contained in the Opinion of the Commission(?) relative to Appendix I which called for realism wherever possible in the definition of input parameters for the dose models. Included in this analysis are dose _evaluations of three effluent categories:

1) pathways associated with liquid efflue~t releases to the Colorado River

2) noble gases released to the atmosphere, and 3) pathways associated with radioiodines, particulates, carbon-14 and tritium released to the atmosphere.

The dose evaluation of pathways associated with liquid effluents was based on the maximum exposed individual. The dietary and living habits for an adult individual included 1) the consumption of 20 kg/yr of fish and 5 kg/yr of invertebrates harvested in the immediate vicinity of the discharge, and 2) recreational use of the shoreline in the innnediate-vicinity of the discharge for 10 hr/yr. 2 j

The do s e evaluation of noble gases rel eased to the atmosphere inc lud ed a calcul at i on of be ta and gamma air doses at the site boundary and total body and s kin doses at the res id ence hav ing the hi ghes t do se . The maximum a ir doses a t the s it e bounda r y wer e foun d a t 1.0 mil e north (distance and direction) rela tive to the South Texas facility. The location of max imum total body and skin doses weze d e termined to be at a residence at 2.7 miles NNW. The dose evaluation of pathways associated with radioiodine, particulate s, carbon-14 and tritium released to the atmosphere was also based on the maximum exposed individual. One such individual is a child whose diet included the consumption of 530 kg/yr of crops, 300 £/yr of milk, and 40 kg/yr of beef and poultry produced at the location of the dairy having the highest calculated dose rfrom these and two other pathways noted below. This location is 7 miles east. Another such individual is a

I child whose diet includes the consumptien of 530 kg/yr of crops grown at the location of the residence having the highest calculated dose from this and two other pathways noted below. These maximum exposed individuals were also exposed to inhaled radionuclides in this category, as well as those deposited on the ground at each of the locations described above.

In addition to the dose estimates for the adult individual, estimates were also made for the teen (12-18 years), the child (1-11 years) and the infant (1 year), with appropriate values of consumption as given in (6) Regulatory Guide LAA. For the pathways associated with liquid effluents, the adult individual received the highest dose. The doses 3 I'--'-*- --* .- -* .. - - --- \. r I

from noble gases released to the atmosphere constituted externa l exposure, and were ther efo re not age- dependent. For the pathways associated with radioiodine and the other radionuclides released to the atmosphere, the child loc a ted at the resid ence received the highest dose at this site. All of the doses in this analysis were based on the radionuclide releases presented in Mr. Boegli's testimony. The dispersion of radionuclides in and the deposition of radionuclides from the atmosphere were based on the analysis presented in Mr. Fairobent's testimony. Comparison of Doses with RM-50-2 Design Objectives As indicated earlier, a comparison with RM-50-2 Design Objectives involves all LHR's at a site. Accordingly, using the procedure described above, a calculation was made to determine the doses associated with combined 2-unit operation. The results*are shown in Table 1 and are compared with the RM-50-2 design objectives. This table replaces Table 5.8 of the FES. ( 8 ) Comparison of Doses with Appendix I Design Objectives In order to make a comparison with Appendix I design objectives, a calculation similar to the one mentioned in the previous paragraph was performed. This computation, however, was performed on a per-unit basis. The results of the calculation are presented in Table 2. 4

Conc l usion It is conc lud ed, bas ed on t he va lu es pr e sent ed in Ta bl e 1 , tha t Lhe agg r e-gate do ses ass ocia t ed with Sout h Texas Proj ec t Un its 1 and 2 op er ation mee t the RM-5 0-2 d e si gn object ives .

It is also concluded, based on the values pres ented in Table 2, that the per unit doses associated with South Texas Project Units 1 and 2 opera-tion meet the 10 CFR SO, Appendix I design objectives. The dose clos e st to the design objective is the dose to the thyroid from gaseous efflu ents. 5

The meteorological data used in this evaluation, conslsting of joint frequency distributions of wind speed and direction r.easured at the 33-ft level by atmospheric stability defined by the vertical temperature gradient measured between the 33-ft and 195-ft levels, were collected onsite by the applicant during the period July 20, 1973 through July 20, 1974. The applicant also provided information concerning topography out to a distance of ten miles from the plant which was considered in the ev~~uation. Information on gaseous effluent sources considered in the evaluation, such as source height above plant grade, efflux velocity, and release point configuration, was provided by the Effluent Treatment Systems Branch of the Office of Nuclear Reactor Regulation. A "Straight-Line Trajectory Model", as described in Draft Regulatory Gui.de 1. DD wa.s used in evaluatini atmospheric transpc,'rt and dispersion characteristics.

An estimate of maximum increase in calcrilated relative concentration (X/Q) values due to recirculation of. airflow, not considered by the straight-line trajectory model, was also considered using the guidance of Draft Regulatory Guide l.DD. Based on the available onsite meteorological data and on the atmospheric transport and dispersion model and guidance provided in Draft Regulatory Guide I.DD, relative concentration values for noble gases and radioiodines and relative deposition values (D/Q) for radioiodines were calculated for the locations presented in Hr.

NRC STAFF RESPONSES TO QUESTIONS OF ATOMIC SAFETY AND LICENSING BOARD CONCERNING HEALTH AND SAFETY MATTERS SOUTH TEXAS PROJECT UNITS 1 AND 2 DOCKET NOS. STN 50-498 AND STN 50-499 I

QlJCSTION 1 The :increased length of the 14 ft . core render::; s l ight ly l ess stable to axial-xenon oscill ati ons , especially l ate :in the fuel eycle : RESAR- 41 suggests (Section 4.3.1. 6) that the part le1gth rods rnay be relied on to as sure stability but the SER, (Sec . 4.3.1) notes a INB probl em associated with the use of PLR' s and says that use of such rods :in Westinghouse reactors is forbidden. Please discuss the alternate control s trategy (West:inghouse Mode A) and its implicatims from the standpo:ints of operational fl exibility and safety.

RESPONSE

Toe restriction on use of part-length control rods in v!estii,ghouse reactors i s expected to be removed in early 1976 f ollowing completion of and n::view by the staff of analyti~al DNB studies being conducted by Westinghouse . In practice, control of the power distribution in_Westinghouse reactors with constant axial offset control (CAOC) procedures (with or without the part-length control rods) effectively prevents xenon oscillations frDm occurring, even ma potentially unstable reactor. This is because constant axial offset control maintains a relatively constant axial power shape during load following maneuvers, so that xenon oscillations are not induced. Being restricted to mode A operation (i.e., without use of part-length rDds), therefore, will not make the reactor more susceptible to xenon oscillations. It does limit operational flexibility, hcwever, because the requirements to maintain the axial flux shape constant dictates that

load changes be made primarily with boron. This is a slower means of maneuvering, especially near the end of core life.

It is D"ivrtan.t to not2 that it is not r, :::cc::::s2.ry to use part- lEcngth cor,t:-D:_ rods to surpress xenon os cillations . Full- length control rods can be used for thi s purpose (see letter to J. F. O' Ledry , AEC, frolT! E. E. Utley, CarDlina Power & Light Company , "H. B. Robinson Unit 2 axial Xenon Osci llations" , October 16, 1972, a copy of which i s attached) . To assess the impact on safety we have evaluated the consequences of xenon oscillation. For example , we may postulate that a xenon oscillation does occur regardless of the constant axial offset control procedures designed to prevent it. During the oscillation the axial flux difference (top minus bottom split excore detector readings) will unde....~o large swings. The constant axial offset control Technical Specifications prescribe a power r eduction to 90% if the flux difference cannot be maintained in a

 + 5% band around the target value, and reduction to 50% power if the flux difference is out of the + 5% band for more than one hour.          The reactor will be safe at half power because the power densities will be reduced by 50 percent. In an extreme case, even if the Technical Specifications ahd alarms were ignored, the overpower temperature difference trip would trip the reactor on excessive flux difference before fuel damage occurs .

QUESTION 2 The SER at p . 4- 12 states that the design. limit peaking factor for the 14 ft. core is 2.50; the SER supplement , at p . 6-1, states that the analyses of ECCS perfonnance. asswned a peaki.rig factor of only 2. i+s. Is the ECCS analysis conservative from this standpoint?

RESPONSE

It is indeed not conservative if the design peaking factor is greater than that assumed for the ECCS analysis. The corrct design peaking factor for RESAR-41, however, is 2.45 as stated on page 4.3-242 of Amenc:1rrent 15 to the RESAR-41 Preliminary Safety .Analysis Re:i::ort. The figure .2,50 in the Safety Eyaluation Report was in error. All the relevant analysis and the staff 's conclusions set forth in the Safety Evaluation Report and Supplement 1 were based on a peaking factor of 2.45.

QUESTION 3 The SER (loc . cit . ) also asserts that the hi3,her value of the peakirig factor for the longer core is associated with the effect of the PLR 's: (a) If the PLR's are not used, will the limit still be 2.50? (b) If a lower limit is established, will control of peaking by simple axial offset observations still be possible at 100% power?

RESPONSE

As discussed in our response to Question 2 the design peaking factor for RESAR-41 is 2.45. (a) Yes, the limiting peaking factor will still be 2.45. Toe limiting peaking factor is established by the loss-of-coolant accident analysis not the use of part-length rods. (b) A lower limit has not been established because as stated above the use of part-length rods will not affect the design peaking factor limit .

QUESTIOH lf The Board notes that one of the consequences of the new (RESAR- 41 ) refuelinf, system i s that fue l will be handled at a shutda. .rn ITBrgin of only 5%. How does this rrargin compare with that generally allowed for fuel handling in T'actors and critical faciliti es at present?

RESPONSE

Historically , the designs of rfueling systems (including refueling procedures) and fuel storage facilities have provided that the keff would be 0.90 or less. This has not been a regulatory requirement, but industry practice. ~ore recently industry has been departing from this practice and we have i ndi cated that fuel may be stored such that keff does not exceed 0.95 in pure water when all physical and calculational un-certainties are included. With rgard to 5% shutdown margin for rfi..eling we find this is acceptable on the basis that with all the control rods re.moved from the core, there is no longer any credible physical change that can be made rapidly on the core that will* substantially increase its reactivity. Continuous flux and frequent boron concentration rronitoring is required during refueling. In practice, boiling water T'actors employ a shutdown margin of 5% during refueling

QUESTIC;~ SA.

Tne SER , at p . 15- 8, stated t hat a revision of the dilution path flow alarms would be required in order to assure adequate warning of potential boron dilution . Supple1T!2nt l, at p. A- 8 , suggests that this will not be required , but that l ocking out of val ves and reliance on nuclear instrwnentation will be substituted. (a) Is this actually the plan? (b) How many minutes warr1ing will the operator have of impending criticality if reliance is placed entirely on nuclear instrumenta-tion for wan1ing of such criticality when it occurs by the rrost rapid postulated reactivity addition rrechanisrn dur'ing refueling? RESPONSE SA The plan adopted by Wes~inghouse for RESAR-41, and committed to by South Texas Project, is to lock closed valves FCV-llOB, FCV-lllB, 8338, 8355, and 8361 in the chemical and volume coni:rDl system, as identified on drawing 9. 3-1, Sheet 3, of RESAR-41. This procedure will eliminate all possible direct paths for addition of fresh water to the reactor coolant system. The only remaining path is via the reactor water storage tank.

The Technical Specifications will require sampling of the boron concentra-tion following JTBkeup to the tank before addition of this water to the reactor coolant system. As an additional precaution, the high count rate will be alarrred in both the containrrent and the coni:rDl room, and a high source range flux level will be alarrred in the coni:rDl room to indicate an a:i;:prcach to criticality due to any unforeseen dilution occurring .
Typically, the source range high flux alarm will be activated one decade above the count rate setting being used. Thus, not only is addition of .

fresh water preyented, but an increase in the subcritical rrultiplication factor is alarrred. Since all credible dilution accident flow paths have been eliminated, the need for p::>stulating operator action following a warning alarm has been eliminated.

QUESTION 58 vmat precautions (suc.h as secondary water treabnent and tube inspection) are now envisaged to assure steam generator tube integrity under all conditions at S1P? RESPONSE SB The NRC staff has evaluated the rreasures that will be taken to assure that the steam generator tubes in the South Texas Project facility will not be subjected to conditions that will cause degradation of integrity. We have also evaluated the provisions rrade by the applicants to detect such degradation, should it occur, before it has progressed far enough to affect the safety of the plant. The facilities, steam generators, and operating procedures described in this construction permit application for the South Texas Project are of more recent design. than those facilities that have experienced ste~n generator tube degradation. This response is directed to the South Texas Project construction permit application. Regarding the newer plants, including South Texas Project,nuclear steam supply vendors of pressurized water reactors that have experienced significant steam generator tube corrosion have redesigned steam generators and rrade significant changes in the secondary system water chemistry. The affected nuclear steam supply system vendors are obtaining experinental data on tube material compatibility in simulated secondary coolant ronditions so that the new pressurized water reactor plants should not have extensive localized corrision

For the South Texas Project steam generators, current regulatory requirerrents are considered.sufficient to insure plant safety at the ronstruction pennit stage of review. If future NRC staff action on this issue or future inspections of operating Westinghouse steam generators develop significant

safety i ssues coneernmg des i gn foatures of systen1s or ca-n:;:x:mer:ts for which preliminary cesizns iliY\:.'. p~oposed in this applicati on , post ccns tr.1c - t i on permit des i gn ch.a1ges ITBY be required of t he applicants . We have concluded that these measures ar\? adequat e. 'H1ere is no reason t o believe that pl ant s afety will be compromi sed by steam generator tube degradat ion . Our conclusions are based on the follading considerations:

1. The steam generators wi11 be of advanced design with improved secondary water flow characteristics, providing more tolerance for occasional lack of water chemistry control.

2. The applicants will use an a11 volatile type of water chemistry that has been sha,m by service experience to minimize the probability of tube degradation.

3. Pruvisions f or monitoring the serondary water chemistry will be included. The se will be used to detect the presence of deleterious impurities before significant tube degradation can occur.

4. Pruvisions for nonitoring reactor coolant leakage to the secondary side are included in the design, and the limits on such leakage that will be l.JTifX)Sed will ensure that tube degradation, should it occur, will be detected before it develops into serious deterioration of integrity.

5. 'Ihe design of the steam generators permits inservice inspection of the tubes by rrethods that will detect incipient tube degradation. 'rubes that could further degrade to rrarginal conditions can be taken out of

service by plugging.

QUESTION 6 The SER at p . 10- 4 states that infor.T:3.ti on will be forthcoming regar<l.inr; the means by which the Applicant proposes to preclude water harrmer in the steam generator feedwater system . Is such i.nfon mtion available? What steps are presently pruposed t o deal with the probl ems?

RESPONSE

The steam generator f eedwater piping wat er hamrrer problem is being .investi-gated by the staff on a generic basis. Work is planned which includes investigation of water hammer phenomena to date in operating pressurized water reactor plants, analytical means to study rrechani sms that may cause water ham11er , recorrunendations for corrective action, including JTDdifications to design and operating procedures to preclude recurrence of such phenomena. i '. The staff plans to use a consultant t o assist in this work . Tests at certain plants on this subject are being closely follawed by the staff. We have discussed this problem with the applicants and have prepared a request for additional information which will be forwaru.ed to the applicants in the very near future. We will evaluate the applicants' response and, in conjunction with the generic investigation described above, detennine the necessary steps to preclude this problem for the South Texas Project. We have determined that appropriate rrodifications of the feedwater system can be made if necessary prior to finalizing the design.

QUESTION 7 What i s the st atus and generaJ. plan of the prograrn me..11tioned in Suppl ement 1 (at p . 18- 2) to review design features int ended to prevent* fires or l imit t he safety consequences of fires?

RESPONSE

The staff is formulating a program to conduct a comprehensive review and evaluation of the fire potential in all nuclear power plants. The review will consider experience gained from the Browns Ferry fire, recommendations from the Nuclear Energy Liability-Property Insurance Association (NELPIA) and from other qualified fire protection consulting agencies. The fire protection systems will be upgraded if the results of our evaluation so dictates. The staff is preparing a technical position which eventually will be used . as a Regulatory Guide, giving the guidelines for fire protection system design f or nuclear power plants. When completed, . we will send this technical position to all licensees and applicants of nuclear power plants requesting that they review their systems with respect to our guidelines, and propose modifications if required. We plan to review each plant individually, and to issue an evaluation with conclusions and/or recorrmendations for each plant .

Dear Mr. O'Leary:

In the interest of keeping the Commission inforr.1cd of any unusual events connect ed with the normal op e ration of a nucle a r po1,:e r station, Carolina Po wer & Light Comp~ny is reporting, by this lett e r, the pres e nce of diverge nt axial xenon o s cillations in the H. B. Robins o n Plant. Continued opera tion with this condition existing in the plant is not in violation of a ny Te chnic.nl Specifi c ati ons or sa fety r e quirements (FSA.R, page 3.1. 2-3), and the magnitude of tl1c po11cr oscillation produced by the xenon oscillation is easily controlled by existing plant equipment. This letter is merely to inform the Comraission of such a condition, and Ca rolina Power,& Ligbt's r..ethod of successfully controlling it. The no ..-mal operation of the Robinson Plant over the last seve r al months has be en base load at full power, with only ~inor de viation s due to forced outages, small load changes as requir~d by the system dispatcher, and a weekly test of the turbine stop and governor valves. This valve test is normally the most significant variation from full power opera tion,' and is instrume ntal in producing significant xenon-iodine imbalances in the axial direction of the core. The power level of the plant is reduced to 70% of _full load and the valves are exercised in turn to deter.nine any sticking of the valves. This exercise is performed to fulfill the warranty requirements of the turbine manufacturer. The power..._reduction is accomplished by inserting Control Bank D to approximately 100 steps and then compensacing for the increase in negative xenon reactivity by the removal of control rods and boron dilution. The time required to return to full power is determined by the successful functioning of the valves, and has been as short as one hour and as long as twelve hours or more.

Upon return to full power, the axial offset of the core, as measured by the excore lone ion chambers, is normally positive, and continued operation leads to a substantial variation in offset (as much as 30% between positive and nc~ative limits) during the first cycle of the oscillation.

The axial stability index of the core has been measured as +0.008, indicating an unstable condition. With this value of stability index, the offset differer,ce mentioned above will ir.crease by approximately 23% from cycle to cycle, eventually leadi.1g to a turbine runback as overpower and over.temperature setpoints are exceeded. l

PENDERGRAFT: We will agree. 14 MRS. BOWERS'. Fine. Well, first I will invite the 15 parties to proceed with any cross-examination of, first, the well, Applicant's and Staff's witnesses are here. They have 16 been sworn and, so, Mr. Pendergraft, do you have questions 17 of either Applicant or Staff witnesses in the Appendix I 18 area? 19 MR. PENDERGRAFT: No. We don!t We don't have 20 any cross-examination on that. 21 MRS BOWERS: . Mr. Stridiron, do you have cross-22 examination questions of the Applicant's witnesses, in the 23 Appendix I area? 24 .!. :, gro l Reporters, Inc . MR.

SHON: I would like to direct one question 9 to Mr. Waterfield, on page 1 of his testimony, regarding I 10 the revised models that were used, revised presumably by 11 Regulatory Guide 1. 8 (a), in a manner that should result in 12 a poor realistic rather than a pessimistic answer. 13 I note you said the models were revised to be 14 responsive to the mandate of the Commission. It that 15 revision a change with respect to the version of these 16 these models that the Commission

had before it when it issued 17 the September 4 notice? Do you know?

18 WITNESS WATERFIELD: Yes. I believe that would 19 believe that would be correct. 20 MR. SHON: Then, as I understand the situation, 21 the Corrunission issued the September 4th notice saying that ah Applicant could opt to conform to .Guide*1 AA, 22 that is a concluding statement. And thereafter you changed 23 something, when you made this calculation and changed it 24 Act .Jrol Reporters, Inc. in a way that would make the answers less conservative ot 25

6 WITNESS WAT ERFIELD: Onl y one I ha ve a de f inite 7 recollection of in that area is that there is one he ad in g 8 for effluent release classifications.which had been jsut the 9 term "gaseous effluents." We felt this was not specific 10 enough and it was changed to "noble gas effluents." 11 MR. SHON: I see. Then that would spe~ifically 12 have borne upon the substance of one of the Board's questions 13 also? 14 WITNESS WATE~FIELD: That is right. MR. SHON: And I think you wrote the answer to 151 16 that, tcq;is that correct? 17 WITNESS WATERFIELD: . Yes' sir. MR. SHON: In p~rticular, then, if there is a 18 I 19 substantive change there, it is with respect to counting 20 only noble gases, rather than particulates and carbon 14 and tritium; is that correct? 21 WITNESS WATERFIELD: The particulates were never 22 included in that . class,I don't believe, because there was 23 another class called radioiodine and particulates." 24 .:.< t ~ral Reporters, In: . MR. SHON: Yes. I recall that is true. 25 I

5 WITNESS WATERF IELD : ~hat is right. 6 MR.

It seems 11 to more than double. Why is that? 12 WITNESS WATERFIELD: I think there must be 13 a typo in this. 14 MR. SHON: Table 1 under i'Liquid Dose to Total 15 Body from All Pathways," . calculated doses lists O. 2 7. Table 2 lists 0.16. That is a factor of very nearly three 16 17 rather than two. MR. STRIDIRON: May we have a moment? 18 WITNESS WATERFIELD: Yes. Now I see what the 19 difference is. In table 1 the dose is quoted as being 20 to total body or any organ. In table 2 the total body is 21 in one category and all the other organs ~e in- another 22 category. It turned out that the total body dose for two 23 units was .12 millirems per year and a half of that is 24 An erol Reporte rs, Inc. 25 . 06.

4 WITNESS WATE R}'I E LD: Tlt c:i t is c o rr e ct . The 5 reas on for chang ing the categori e s is, we we r e att emp ting 6 to follow the categories that h ad be en ori ginal l y l aid ou t 7 in the two Commission documents. The ~M 50-2 had t he 8 once classificatio~, whereas Appendi~ I has a differ en t 9 classification of the way to apportion the doses. 10 MR. SHON: I see That clears it up. 11 I just got your response to our ques~ions this 12 morning, but I think if I .understand it correctly, what m:i 1 lli 13 you are saying is that the ten millirad gamma and twenty 14 millirad beta per year do not include things other than the 15 noble gases; is that right? 16 WITNESS WATERFIELD: Yes. That is right. MR. SHON: Why can we assume that that is what 17 the Commission meant when it said "air dose"? . Don't 18 these thingscontribute to an air dose? Don't they, indeed, 19 20 cause ionization? WITNESS WATERFIELD: Yes. They do. But I think 21 the original intent was the air dose should bear some . 22 fairly close relationship to - tissue dose and in the case 23 of these nuclides, why that just doesn't happen. And we felt 24 Ac, .erol Reporters, In,. it was more appropriate to include them in the other 25

3 MR.

BOWERS: Mr. Schwarz? 14 MR. SCHWARZ: No, Mrs. Bowers, we have no questions. 15 MR. SHON: I had a couple of small questions of 16 Dr. Rodger on his testimony at table 19 in the very nicely 17 prepared little booklet here. 18 The statement starting on page 5 of the testimony 19 and running through page 6; says that the vapor from the 20 blowdown tank is condensed in feed water heaters and all of 21 the l i quid is returned to condenser . hot w~ll. rt may be 22 you are not e x actly the person to answer this, I am not sure, 23 but are there no noncondensables? Nothing results in the 24 Act e rol Repo rte rs, Inc. form of a gas at all from that? 25 I

11 I! Ii 1 ;! bw8 'i'HTL'-iESS FODCE R: I believe these things will 21 also ven t back to th e condens er hot we ll and the non - I' 3 condensables will be vented along with the noncond e nsabl e s 4 from the secondary system and , therefore th . e contributi o n 5 is accounted for. 6 MR. SHON:* I see. 7 It all goes out the air ejector of the system.* 8 On page 9, in several places it is noted that 9 distillants and other materials are released, released 10 with further processing after analysis. Previous paragraphs 11 mention a similar sort of practice. What kin~ of control 12 does one have to assure that a thing is not released without 13 being analyzed first, that it is held onto? Is it purely an 14 administrative control? 15 WITNESS RODGER: I am not sure that that aspect of 16 this plant has been fully addressed as yet, but normally, 17 and in this case, too, the liquids for release are collected 18 in tanks and these tanks Bre always in at least pairs, so 19 that ~ou can stop putting into tank after you take the 20 samples for analysis. There is always a lot o~ paperwork associated with 21 it, and one has to get the results back from the analytical 22 laboratory, and it is the normal practice, and I presume 23 will turn out to be the operating practice of this plant, 24 A: .eral Reporters, Inc. too, that the lines or valves through which liquids are 2.:>
