ADDENDtN TO SAXTON CORE III LICENSE APPLICATION Introduction This addendum to the Sexton Core III Safeguards Report contains proprie-tary information on load follow fuel rod design which amplifies the de-scription of those rods in the main body of the 'eport. The types of ex- 1 perimental fuel rods and the ranges of rod design values are given here.

The calculational basis for nuclear and thermal-hydraul) designs is dis-cussed in full in the safeguards report and is not repeated here. Me-chanical design, with the exception of a detailed listing of fuel rod variables, is covered in the main report; only a brief description of as-sembly_ design is repeated here. An evaluation of thermal-hydraulic and mechanical performance of these test rods which confirms that a 1 test rods satisfy the applicabic design criteria is summarired in this report. __

The six rods (of the 120 load follow rods) which contain pressure control devices are designed such that internal pressure may exceed primary system pressure et the end-of-life. These rods were analyzed to assure that the clad stress and strain design criteria are satisfied.

~

Test Objective and Mode of Operation The objective of the load follow experiment is to determine the effect of fuel rod linear power level, fuel density, fuel-clad gap and internal pres-sure on fission gas release, fuel swelling, and clad strain behavior under power cycling conditions. The study includes combinations of rod design variables representative of both current and developmental fuel designs.

Throughout Core III operar n .he assemblies vill be subjected to several power cycles each day. The lower limit of the cycling range may be re-1

st ricted by Saxton plant capabilities, but is expected to be in the vici-nity of 40% of fall power. The upper limit of the cycle vill bu limited to 100% of full power, as defined in the safeguards report. Iu addition, mid-way through Core !!! 11(c the positions of these two assemblies will be interchanged to simulate power letsi increases associated with fuel management techniques which tre movement of f uel assemblies from low power cere regions to high pow sre regions.

Load Follow Assembly Design The load follow assemblies are similar in design to previous Saxton as-semblies. Tte arrangement of fuel rods and other fuel bundle components of the assemblies is shown in cross section in Tigure 1. Three tie rods hold the 'ranovabic top nozzle in places Two tie rods are Inconel-filled stainless steel tubes and the third tie rod is a stainless steel tube vith a stainless steel filler rod. Five water-filled tubes are used to increase the water-fuel ratio in the center of the assembly and thus in-crease the power level of the adjacent fuel rods.

Tuel Rod Design A number of combinatiocs of the variables listed in Table 1 are included in the 120 fuel rods comprising the two load follev assemblies. The majority of the rods are Zircaloy-4 clad. The several stainless r.cel .

rods are included to study fissior, gas release and fuel swelling with minimized sensitivity to clad-pellet gcp conductance. Six pressurfred rodo contain pressure control chambers located in the top plenum bpacc to limit the range of internal gas pressure from beginning to end of core life. The chambers consist of stainless steel belov vith brated thin diaphragm end closures designed to rupture at internal pressures not to e, m ad-2800 psi. The rods v!th pressure control chambers will operate > peak linear powers in the range 14.5 to 19.9 kv/ft.

ruel Rod Performante r All of the Load Follow test rods vere designed to avoid fuel meltics, The highest temperature (4600'F at beginning-of-life approximately 500*r below g

the melting point) will occur in a Zircaloy-clad rod at peak design power of 19.9 kv/ft with 89.5% T.D. fuel, an initial pressure of 15 psia . air. 3 With continued irradiation, fuel thermal expansion,and clad creep down tend to increase the fuel-c1cd gap conductance and ti.erefore decrease the fuel >

temperature. Other design combinations were evaluated for initial internal gas pressures up to 500 psia, fuel density up to 94.5% T.D. and fuel-clad gap up to 9.5 ' tis. Because of the higher fuel-clad gap conductance re-sulting from t i higher pressure and because of the higher thermal conduc-tivity of the ,h her density fuel, peak fuel temperatures were predicted to be less than in the case stated above.

The highest internal gas pressure conditions will exist in Zircaloy-clad rods containing pressure control chambers: in several of these rods pres-sure will exceed coolant pressure. llowever, even in the event that the pressure chambers fail to rupture as designed, the clad stress will still be considerably below yield stress and total clad strain will still be 1ess than 1%.

For the Zircaloy clad rods which do not contain pressure control devices, the lead rod end-of-life internal pressure will be less than the 2250 paia primary system pressure. The lead rod design parameters are 89.5%

fuel density, 500 psia initial internal pressure, and 9.5 mil initial fuel-clad diametral gap. At the design peak burmup of 21,000 MWD /MTU, fission gas release is expected to have a minor ef f ect on the total inter- 1 pressure. liigher fuel density and smaller fuel-clad gaps are more moder-ate design combinations leading to increased fuel-clad gap conductance, lower fuel temperatures, lower fission gas release and lower end-of-life pressure. In none of these temperature and pressure Ifmiting combinations does the total clad strain exceed the design limit of 1% in the Zirealoy clad fuel rods.

1 The questione of fuel t(uperature and internal pressure are also con-sidered for the 18 stainless st eel-clad f uel rods in these two asstub11es.

The tembinations of gap, f uel density and linear power have been chosen to avoid fuel melting and end-of-lif e internal pressures exceeding cool-ant pressure in the stainless steel rods. The higher strength of the stainless steel cladding assures that clad strain at end-of-life vill be less than 1%.

source for them 1

Pursuant to the Freedom of information Act. I also request both I representative of the news media status and a public interest waiver of all search and copying fees A publicinterest waiver of search and  !

copying fees has been provided by llugh L Thompson Jr., deputy executive director for nuclear materials safety, safeguards and operations support in connection with previous FOI A requests for this  !

The dc<uments will be used in preparation of a definitive history of General Public litilities IGPlh, the Three Mile Island nuclear accident and its impact on the world (2) Explain the extent to which the requester will extract +

and analyze the substantive content of the agency record.

1 will provide a great deal of analysis to the information in the documents I obtain from the NRC. I will match it with mlormation I obtain from other sources,like personalinterviews, and use all that information to write a comprehensive, truthful and objective book that will (l1 tell the history of the commercial nuclear industry.

(3) Describe the nature of the specific activity or research  !

in which the agency records will be used and the :pecific j qualifications the requester possesses to utill:.e information  :

for the intended use in such a way that it will contribute to public understanding.  :

i i plan to use the NRC records to write a definitive history for the l general public of the Three Mile Island nuclear accident of 1979 and  !

Its impact on the world. The book will describe the events leading to  !

the accident, the accident itself, and what happened at TMI and to the  ;

nuclear industry in the 10 years that followed, and what the future  ;

might hold for nuclear power in light of concerns over global warming. i i

I have considerable experience 'in making compleI scientific or technical stories accessible and interesting to the general public. My first book. Ihseen D.tnser: A Trase& WPeople. Gwernment .indthe l

Centr.th> Jhne/#e (University of Pennsylvania Press 19861 required me to make a complex geological problem understandable to people .

who were not,in most cases, geologists or scientists. The reviews my l hook received testify to my success in carrying that out.

I covered the nuclear energy beat for Ihe Patriot Ns1in Harrisburg for about two years (until GPU Nuclear succeeded last February in having me removed from the beat because 1 am writing this book an arbitration ruling in my grievance is pending) and

, acquired a working knowledge of nuclear terminology and procedures.  ;

if there was something i did not understand about something I had i read, I would call an expert who could help me. I would do the same tf there was something I did not understand in the documents I seek in ,

as wh.it happened to GPU and the rest of the nuclear industry in the years that followed.

My boot will be more than just a simple retelling of the TMl accident. I will place the accident in the context of the rise and Iperhapsi f all of the commercial nuclear industry in the U S and the world.

I intend for my b(ot to be the one people pick up at the library in years to come when they want to know the who what why-when-where and how much of one of the more significant technical. business and historic events of the late 20th century, it will distill the important information from the tens of thousands of government dxuments pertaining to TMl technical papers written by scientists.

and the many other sources of information into one good book (5) Describe (lic site and nature of the public to whose understanding a conitibutions will be made.

This book is being written for the general reading pubhc--the average man or woman who doen not work for the NRC or the Department of Energy or the nuclear industry and who typically would only receive information about IMI from a book acquired at a library or bootstore. I would estimate this to be quite a large, diverse group (6) Describe the intended means of dissemination to the public.

A book.

(7) Indicate if public access to information will be provided free of charge or provided for an access fee or publication fee.

Readers will be able to borrow the book free of charge at public hbraries

l

-(8) Describe any commercial or private interest the requester or any other party has in the agency records sought.

I have no commercial or private interest in the NRC documents sought in this request. They will be used exclusively for research for  !

my book and will not be sold.  ;

(d)(1)llow the subject of the requested agency records concerns the operations or activities of the Government.

It has been the duty of the NRC, and the Atomic Energy Commission before it to regulate the U S nuclear industry, a duty that includes investigation of nuclear accidents.

l (d)(2)llow the disclosure of the information is likely to contribute to an understanding of Government operations or activities.

The documents will be used in a book about General Public Utilities. the TMl accident. and its impact on the world Readers of the book will come to understand the role of the NRC and the AEC before  ;

it. in supervising the U.S. nuclear industry, and of the AEC in promoting the U.S. nuclear industry. ,

(d)(3) If disclosure of the requested information is likely '

to contribute to public understanding.

To the best of my knowledge. no definitive history has been written about the TMI accident, and none of the books that have been i written fully describe the history of GPil s involvement in nuclear energy.

(d)(4) If disclosure is likely to contribute significantly to public understanding of Government operations or activities.

The docunients will contribute significantly to a general public understanding of the_ role of the AEC in regulating and promoting 1

L

i nuclear power and of the NRC in regulating it. Relatively little has ,

been written by non-government sour:es about the early history of t commercial nuclear energy, and to the best of my knowledge, nothing has been written for the general public about GPU's early involvement l with nuclear energy Thus, the requested documents will make a l significant contribution to public understanding. The corporate ,

i documents will contribute to public understanding in the same manner. As for the state police documents. they show the range of  :

areas investigated by the NRC after the nation's worst commercial -

nuclear accident.

(d)(5) If, and the extent to which, the requester has a i commercialinterest that would be furthered by the disclosure of the requested agency records.

l anticipate receiving royalties on the book, perhaps in four or five years. llowever, there is no guarantee I will make any profit on the book,it is often said that most authors would make more money by spending the same amount of time working in a fast food restaurant. ,

My first book, Unseen Danger, received f avoracle reviews, including one in The New York Times was purchased for many libraries and earned me enough to buy a nice topcoat. which I still have but which is starting to show its age, I hope this book will do better, but one never knows.

(d)(6) If the magnitude of the identified commercial interest of the requester la sufficiently large, in comparison with the public interest in disclosure, that disclosure is primarily in the commercial interest of the requester, i

As I have stated, the documents will be used in a def mitive history of the TMI accident and its impact on the world, I anticipate receiving royalties, but i believe the public interest in disclosure of the. t L documents clearly outweighs any minimal commercial benefit to myself.

- The public has an especially significant interest in this issue because of the global warming problem. Nuclear power production -
