.~N lRE!:iPECT TO BOARD. QUESTIONS 111, tt2, tt3,

. OF OKDeR DATED APRlL 18, 1Y79 My analysis of the accident of Three Mile lsland and the. potential involvement of the spent fuel pool and how that relates to Salem 1, necessarily involves some discussion of my opinions as to the use of Zirconiu:n Alloys as cladding -for the uranium dioxide fuel pellets *in nuclear reactors.

I believe the reactor at Three Mile lsland underwent a major temperature excursion during which, from available information, 1 would conclude that 10% - 15Z of the Zircaloy cladding reacted with steam to form Zirconium dioxide and hydrogen. This reaction furnished most of the hydrogen in the bubble at the reactor head.

Part ot the hydrogen probably penetrated the oxide film on the Zircaloy II cladding to dissolve in the metal and to torm zircon;t.um hydride, ZrH1

  • 4
  • This hydride has low hydrogen equilibrium pressures at the nor:nal operating temperature ot the reactor. Such reacted hydrogen obviously cannot be vented. I have prepared pa,pers reported in the literature which described my work on this reaction. This work showed that hydrogen gas rapidly penetrates the oxide. At defects and edges spalling of the hydride and oxide could occur. I suggest that this reaction may have occurred in the reactor absorbing the hydrogen bubble. .With or without spalling embrittlement of the cladding must have occurred with serious damage to the Zircaloy in the reactor. The spalled zirconium

hydride and zirconium oxide would fall to the bot.tom of the reactor together with the fuel pellets. The circulating cooling water continues to react with the treshly spalled zirconim hydride suf aces forming more zirconium dioxide and hydrogen. 1 predict that this reaction will continue until all of the Zircaloy II cladding is reacted.

As a result of the above analysis,.I suggest the following procedures:

1. Hydrogen in the cooling water should be ourned catalytically to prevent build up of another hydrogen buble in the reactor.
i. The low temperature Zircaloy II - water reaction will continue as noted above. All released gases must be filtered and trapped before burning to remove radioactive gases and radioactive particulates. The only safe chemical and conditions after an accident like that at Three Mile island is to have all of the Zircaloy II reacted to the oxide.
3. Hydrogen in the circulating cooling water must be monitored and removed until a near zero value is attained to insure that no metal and hydride remains. A temperature excursion with unreacted metal and hydride in the reactor could lead to reformation of the hydrogen bubble. Hydrogen gauges of high _sensitivity are now available or could be made in a short time.
4. I am much concerned about the e£fect of hydrogen on the reactor vessel and piping.

I strongly recommend that experiments be made on hydrogen embrittlement of the alloys used in the reactor and piping under conditions simulating those which occurred in the reactor.

5. I strongly recommend that experiments should
  • be made on the effect ot hydrogen in the cooling water at high pressure on pre-oxidized Zircaloy II to evaluate the penetration and pick-up of hydrogen as a tunction of temperature and pressure *
6. 1 recommend calculations on how much of a rapid Zircaloy II - steam or water reaction could occur before the hydrogen formed embrittles the cladding and ruins the reactor.
7. ~en~it1ve hydrogen gauges should be instaLled on the primary and secondary loops and on the reactor itself to monitor the Zircaloy IJ. -

steam anct water reaction.*

I should like to repeat -that these suggestions are b'ased on extensive research in the field of gas-metal reactions. My own basic research on zirconium began 1Il 1~47 oefore the ronnation of tne lJl::!st.i.ngnout:1e Bettis Atomic Power Laboratories. Twenty years of nearly continuous research was conducted on the* reactions of zirconium, Zircaloy ll, Z1rcaloy IV and the other zirconium alloys with oxygen, air nitrogen and water vapor over a.

temperature range of :.!5°C to HOO"'C and at pressures. of a few torr to over luO atmospheres. This work was reported in 25 papeYS.and many research reports to the Westinghouse Electric Corporation.

Many important tehnical problems we.re solve& :including the solubility of hydrogen in zirconium, the crystal structure and range of homogeneity.

of zirconium hydride; ZrH1 . 4 , the rate of diffusion of hydrogen in zirconium, the role of oxide films on hydrogen adsorption, the rate of oxidation of zirconium in oxygen, the rate of nitride formation in nitrogen, the types of hydrogen reaction with zirconium intermetallic comipounds, the rate of reaction of zirconiUI!l alloys in water at high pressure and the behaviour of Zircaloy II in fast flowing steam at temperatures above 1000°C.

After 25 years of research and development on !:he chemical and and metallurgical properties of metals and alloys used in nuclear power plants, I have come* to the conclusion that the current design and materials cannot give us a safe and well-~ngineered nuclear power plant.

The use of zirconium ailoys as cladding material for the hot uranium oxide fuel pellets if a very hazardous design concept since zirconium.is one of our most reactive metals chemically.

At tne operating temperature of nuclear power reactors zirconium cladding alloys react with oxygen in water for form an oxide layer which partially dissolves in the metal embr1ttling and weakening the metal tubing. Part ot the hydrogen formed in the zirconium metal reaction dissolves in the metal and may precipitate as a hydride phase also embrittling and weakening the metal tubing.

At temperatures *above i,1U0° Celsius (198U° Fahrenheit) zirconium reacts rapidly with steam with a large evoiution of heat and the formation of free hydrogen~ with most metals to form intermetal.~ic compounds and with other metallic oxides to form its own oxide. Once zirconium is heated to 1,100° L:clsius, which could occur in loss of coolant accidents, its is difficuit to prevent further reaction, failure ot the tubing and of the reactor.

Tnere appears to be no way to overcome the inherent material problems associated with zirconium alloys and the current design of the reactor ureater wall thickness f ot cladding and lower operating termperatures of the fuel may help but the chemical and metallurgicai behaviour of -zir~dnl.um alloys cannot be overcome. No backup or alternative design is available if the present design and materials prove unreliable.

Considering the potential and consequences of a mel.tdown or explosion as.posed in tne Board's question, 1t would be more consistent with the safety and health of the public to store spent fuel away from operating nuclear reactors. The storage of spent fuel in spent fuel pools at reactor

sites in close proximity to operating nuclear reactors for long periods of time and in large quantities represents a significant involvement ot large amounts of radioactive material in the event a serious nucLear accident.

4.3 Closure In surnmnry, I spent 4 ycnrs nt Tufts University doing independent teaching and crea,ti ve research. nuring this period I maintai.ned 4

close comnnmication with the teaching and research staff at Harvard University and Massachusetts Institute of Technology by attending weekly seminars and by attending local scient~fic society meetings. None of trf'/ supervisors were Registered Pro-fessional Engineers.

s.o Westinghouse Electric Corporation, Research and Developr.:ent Cen-ter, Pittsburgh, Pennsylvnnfo. July 1, 1940 to Present.

Due to difficulties in financing research work at Tufts, I de-cided to leave Tufts University and join the Westinghouse Re-search Laboratories. Westinghouse, at that time, was attracting many good people with opportunities to work on basic research problems of interest to the electrical manufacturing industry.

5.1 Between July 1, 1940 and about July 1, 1947, I was employed as a Research Engineer in the Chemistry and Metallurgy Department.

My supervisors were, chronologically: Messrs. A.A. Bates, Mana-ger, Chemistry and Metallurgy Department, and R.W. Auxier, Mana-ger, Chemistry Department. Neither were Registered Professional Engineers.

s.1.1 Oxidation of Metals My primary project was (1) to develop methods for the study of gas-metal reactions, (2) to use these methods for the study of the oxidation of a vnriety of the conunon metals and al.loys and (3) to develop theorcti cnl models to explain the experimental results. I developed for these studies a very sensitive micro-balnnce which was pl accll in the re;1ct lon system for dete.rmining the kinetics of .oxidation of metals. I developed a special electron diffraction cnmera for the study of the surface structure of the oxide films forml'<l *on m<.*ta l!I nt tcmpernturcs up to 1000°C.

I also developed with my co-workers methods for Using the newly developed electron microscope for the study of the crystal habit of oxide films formed on metnlR during oxidation.

Twenty basic papers were pub! i8hcd <luring this period on (1) the kinetics of oxidation, (2) the crystal structure of- the oxide films

  • and (3) the crystal habit of the oxide films. These papers are listed as papers number 4-23 in Section 6. The vacuum microbalance method has been duplicated and used throughout the world for gas-metal studies. We have also contributed extensively to present understanding of the crystal structure and crystal habit of oxide fiims on metals.

s .1. 2 Consulting Activities During this period I acted as a consultant to the Westinghouse Lamp Division on metal problc.>ms. I afoo consulted with the electronics department, metallurgy department and chemical department at our Lnhoratories.

5 .1. 3 World War II Work During the period of 1942 - 1945, I worked on new methods of under-6

water propulsion, including rocket and jet propulsion *. primary batteries, chemical power plants and gas turbines. I also car-ried out, with the help of technicians, experimental work on duct propulsion for torpedoes.

My suggestions on primary batteries led to a large contract with the govetnment for the production of a new type of battery powered torpedo. lbis work was terminated in 1945 at the end of the war.

5.1.4 Closure During this seven year period I worked as an independent research engineer. For part of the time I supervised the vork of 1-4 professionals and technicians.

7

5.2 July l, 1947 to July 1, 1966, Advisory Engineer My supervisors were, in chronological order: R. Auxier, Manager, Chemistry Department, and W.T. Lindsay, Jr ** Manager, Physical Chemistry Department. Neither were Registered P'rofessional Engi-neers.

On July l, 1947, I was promoted to the position of Advisory Engi-neer, In this position, I conducted basic research projects di-rectly and with the help of other professionals and technicians.

I was primarily responsible for the administration, conduct and reporting of basic research activities in the area of surface reactions of gases with metals, alloys, non-..eta1s and oxides and the corrosion of metals and alloys, I reported directly to the manager of the Chemie try Department.

Our research activities were of three types: (1) programs developed in cooperation with Di visions of Westinghouse, (2) programs spon-sored by U.S. Government agencies and (3) basic research programs initiated to solve long-range research objectives of the company, The apparatus, 100thods and trcntment of the problem were essential-ly the same for the three types of research activ.lties.

5.2.l Gas Reactions of Carbon ~)0 - 1500°C This work was done for Bet tis Atomic Power Divisi.on and Astronuclear Di vision to provide basic inform.it ion on the react:ivity of carbon at high ter.:perature in the v:irious n1.1clcar power devices. Extensive studies were made on the reaction of pure graphite, pyrolytic car-bon and doped carbon lll.'.lterials with oxygen, a1r, hydrogen, carbon dioxide and helium at temperatures of 300° to 150{)°C, over a wide pressure range from a fraction of a torr to 76 torr and under a wide range of flow rates.

This \.'ork was done over the fifteen year period o-f 1950 to 1965.

The results were of immediate vnlue to the Oivisiuns. In addition, the "ork led us to a new Wlderstand ing of gas-solid reactions where the reaction product also was a gas. This work W'as reported in papers number 44, 45, 46, '~7, 113, 116, 117,' 122. 123, 124, 125~

126, 127, 135, 143, and 157 of the papers listed in Section 6.

Reaction of Zirconium and 7.irc~-!..~ Alloys t.rith Oxygen, Hydrogen, Nitrogen and Water Vapor This work was done for the Atomic Energy Commissi.on, Bettis Atomic Power Laboratories ancl our Commcrc i nl Atomic Power Di visions. The work was begun as a basic rcs~~rch program in 1947 before the for-mation of Bettis Atomic Power L.:lboratories. Twenty years of nearly continuous research ef furt. w:1~ carried out on the reactions of zir-coniu::i, Zircnloy II, Zjrcaloy lV :md numerous other zirconium alloys 8

with oxygen, air, hydrogen, nitrogen and water vapor over a*

temperature range of 25° to 800°C and pressures of a few torr to over 100 atmospheres. This work was reported in 25 papers which are referred to in Section 6 as papers number 35, 56, 56a, 59, 61, 62, 66, 68, 69, 70, 72, 73, 75, 77, 78, 79> 92, 132, 136, 137, 138, 142, 143, .146 and 151.

Many technical. problems were solved in these studies incl~ing the solubility of hydrogen in zirconium, the crystal structure and range of homogeneity of zirconium hydrides. the rate of dif-fusion of hydrogen in zirconium, the role of oxide films in hydrogen adsorption, the rate of oxidation of zirconium in oxy-gen and in nitrogen, the types of hydrogen reaction with zi*r-conium intermetallic compounds and the reaction of zirconium al-loys in water at high pressure.

5.2.3 Oxidation of*the Refractory Metals, Tungsten, Molybdenum, Rhenium, Niobium and Tantalum

!bis work was done for Wright-Patterson Air Force Laboratories, U.S. ArrirJ Office of R~search,, Durham, Westinghouse Lamp Division and for Westingho~e Basic Research programs.

Twenty-six years of research effort was carried out on the reactions of ttmgsten, molybdenUI11, rhenium, niobium and tantalum with OX"j-gen, hydrogen and hydrogen-water vapor gas mixtures over a tempera-ture range of 25° to 2700°C, a w:f ck pre:*rnure range and in static and flow reaction environments. This work was reported in 20 papers which are referred to in Sec ti on 6 as papers number 17, 20, 21, 33, 37, 91, 106, 110, 111, 112, 113, 115, 117, 123, 129, 147, 156, 157, 159, 164 and 166.

The studies included kinetic studies on the oxidation reaction and the role of volatile oxide species on the rate of oxidation, the crystal structures of the oxide films, the mechanisms, of oxidation and the therioochemical stability of the oxide species.

Many technical problem were solved in these studies. The work pointed out the difficulties inherent in using these materials in high temperature oxidizing gas environments due to the formation of volatile metal-oxide gas species. Studies on the sintering of silicon, aluminum and potassium doped tungsten ingots showed the important role of the oxygen potential of the hydrogen-water vapor gas mixture in controlling the composition and properties of the tungsten ingots. Vapor pressure studies on molybdenum oxides demonstrated the high volatility of the trimer (Mo03) J9 5.2.4 Localized Oxidation and Stress Corrosion Cracking of Metals lnis work was ~tarted as n basic rcsenrch program and later sponsored 9

by the Office of Naval Research an<l the Westinghouse Stress Cor-rosion Cracking Committee. Eighteen years of research work was carried out on the nucleation of oxides on iron, the formation of oxide *hiskers and hladc;_shnpcd nnd. fan-ehap~d oxide platelets on iron and the mechanism of stress corrosion cracking of metals.

1bis work was reported in 20 papers which are referred to in

.section 6 as papers numbeT" 57, 58~ 65a, 83, 86, 88, 89, 90, 103, 104~ 105, 114, 121, 148, 149, 150, 153, 155, 158 and 165.

The results of this work has suggested new models for the oxidation of metals, new mechanisms for the rapid transport of metal in oxide structures and a new model for the stress corrosion cracking of .

metals.

5.2.5 Oxidation of Alloys This work was started in 1945 as a basic research progra~ since Westinghouse was interested in developing better heat: resistant alloys for electric stoves, steam and gas turbines and for use .

in a wide variety of electrical apparatus. Twenty years* of re-search was carrie.d out on the kine tics of oxidation of type 304 stainless. steel, nickel-chromium-aluminum and iron-chromium-alumi-num alloys~ Crystal structure nncl crystal habit stud:i1!s on the oxide films ,.as correlated with the kinetic observations. This '*'

vork was reported in 16 papers which are referred to f,11 Section 6 as papers number 15, 16, 17, 19, 25, 26, 27, 29, 31. 52, 55, 63, 80, 84, 85 and 97.

These studies were vn l unblc in es tab 1 ishing the Wlique Tole of chrocium, aluminum, manganese, silicon and trace impurities in high temperature oxidation.

5.2.6 Thermochemical Analyses Thermochemical analysis was used as a discipline to gu:lde us in planning and interpret in~ all* of the research programs. In the early 1940's we searched the litcrHturc and assembled free energy and equilibria data on many oxi<l~ systems to evaluate t:he oxida-tion, reduction and sintering reactions of metals. This compila-tion of thermochemical informn ti on w.1s one of the first and was very important in our own work an<l as a help to others in our laboratory and in Wes tinghousc Di visions. Three special studies were made to develop thcrmochcmicnl qunntitics to help in our own studies: (1) vapor pressure of h~ryllium, paper number 38, (2) va-por pressure of chromium, papers number 50 nnd 67 and (3). vapor pressuT"c of molybdenum trioxide, pnpcr number 111. These papers helped us to develop models for the oxidation of beryllium, chromi-u::i and molybdenum.

Experimental thermochemical studies were also made for (1) zirconium-10

hydrogen system, papers number 59 and 62 and (2) columbium-hydrogen system, pa~er number 106. lbe results of this work were very valuable in using zirconiUID alloys as a cladding material in pressurized water nuclear power reactors.

5.2.7 Closure All of the work during this period was t.mder my direct supervision.

I participated in the planning, carrying out of the experiments, in the interpretation of the results and in the write-up of the results. During this period I supervised the work of 4-6 profes-sionals and 2-4 technicians, 11

5. 3. 2 Oxidation of Silicon and Silicon Carbide This work "1as begun by the Army Office of Resenrch, Durham, and .

later *continued as a basic research project *. Studies were made on the behavior of silicon, s 111 con oxide and silicon carbide in oxidizing and reducing gas atmospheres and in high vacuurn.

These studies confirmed thermochcmic.:i l predictions of two types of oxidation processes, active and passive. Very rapid oxidation (active) occurs in low pressure oxygen using high flow rates with loss of silicon monoxide and carbon monoxide. Very slow (passive) oxidation occurs in high pressure oxygen even in high flow rates with the formation of n protec~ive oxide. Thermo-chemical analysis shows the equilibrium pressure of silicon monoxide at the silicon/silicon dioxide or silicon carbide/sili-con dioxide interface determines the type of oxidation reaction.

The results of these studies were reported in papers number 133, 134, 156, 157, 158, 160, 161, 163 and 164 in Section 6. The re-sults of these studies have led to a new un~erstanding of high temperature oxidation of materials where volatile gases are formed at internal interfaces. Also, the success of the use of thermo-chemical analysis in the interpretation of oxida.tion has led to many new applications of thermochemical analysis in industry.

5.3.3 Hot Corrosion of Gas Turbine Alloys Tilis work developed from our interest in applying thermochemical analyses 'to high temperature cor roB ion processes in gns turbines, A lengthy paper entitled "Gcnernl Concepts of Oxidation and Sulfidation Reactions -- A Thermochemical Approach" was written.

This paper was published and is llstcd as pap.er number 160. This paper has led to further work with the Coal Gasification Project.

Here, cleaned low BTU coal gas will be used in n gas turbine at 1600°F. Thetmochemical analysis is being -used to guide us in planning and interpreting the extensive experimental program.

5.3.4 Sintering of Tungsten for Incnndesccnt Lamps Extensive thermochemical analysis has been used. to study the in-fluence of temperature and dew. point *of the hydrogen g~s used in the sintering process on the density and silicon. aluminum and potassium analysis of the tungsten. A special high temperature, high vacuum furnace was installed to carry out sintering reactions in high vacuum of 10-7 torr and in controlled hydrogen/water vapor gas mixtures at temperatures to 2700°C. This work demonstrated the important role of the dew point (oxygen potential) of the hy-drogen gas on the density and silicon, aluminum and potassium levels.

The experimental work con firmed the thermochemical predictions.

11.0 Summary Thirty-three of m'f thirty-nine years of scientific and engineer-ing experience have been in the field of gas-metal and gas-solid reactions including research, development, ~onsul ting and super-vis ory activities.* lbe time span of 1940 - 1973 includes the period in which gas-metal reactions were juet beginning to be studies in our unlversities to the present period where the study of gas-solid reactions is essential iD the preparation and use of materials.

  • My first activities at Westinghouse were to develop new and im-
  • proved instruments for the study of gas-metal. reactions. We de-veloped the vacuum microbalance method for die study of the kinetics of oxidation, medium and high vol~aige electron diffraction methods for the study of the crystal structmre of thick and thin oxide films and electron microscope methods f'or the study of the crystal habit of oxide films. A combinatioa of these methods was used to experimentally characterize a wide variety of oxi-dation, volatilization, hydrogen rcductioa amd hydr1ding reactions.

A second phase of this work was to interpret. the results of the experimental studies. We made important theoretical contributions

  • to gas-solid reactions us!ng thermochemical analyses* kinetic theory, transition state theory of chemical reactions, diffusion theory and classical di ff us ion rn te theory *.

. We have studied over a thirty-three year period a broad spectrum of gas-metal and gas-solid reactions. lbe oxidation reaction of the following elements and alloys have been studied: iron, nickel, cobalt, copper, aluminum, magnesium, chrondmm, berylliunt, titani-um, vanadium, zirconium, rhenium, silicon, niobium, tantalum, molybdenum, tungsten, uranium, stainless steels, nickel-chromium, iron-nickel-chromium, iron-chromium-aluminum, zirconium-tin, Zirc-aloy and a large number of zirconium-intermecallics. The hydro-gen and nitrogen reactions of zirconium, titanium, niobium, tanta-lum, Zircaloy and the zirconium-intermetallics '"'ere studied. We have worked extensively on the oxidation, reduction and volatili-zation reactions of SiC, Si02, A1 2o3 , W-0, Mo~ and U-0 systems.

Over the years the gas environmeT"ltS have changed from simple oxi-dation and reduction gas environments to complex environments of mixed gases such as hydrogen-water vapor gas mi.xtures, inert gases containing traces of water vapor, nitrogen, oxygen, etc. and air containing water vapor and traces of sulfur gases. Also, temperatures have risen from temperatures below 1000°C to temperatures up to 280C°C. *These t:rends in more complex 30

reaction environments and higher temperatures has required a great deal of care in the planning and interpreting of the data.

My professional activities have brought me into contact with a wide spectrum of products: nuclear reactors, steam generators, electrical generators, gas turbines, motors, transformers, fur-naces, ovens, electrical heaters, incandescent lamps, flourescent lamps, automotive lamps, cameras, . flash lamps, high temperature materials, ceramics, electrical heater alloys, magnetic alloys, protective coatings,. electroplated coatings and corrosion resistant alloys.

From the beginning I have been affiliated with individuals and groups dedicated to solving technical problem using the best

  • of modern theoretical and experimental methods. My scientific
  • work has taken me to meetings and discussions all over the United States. and in many foreign countries including Canada, England, France, U.S.S.R., Japan, Norway, Sweden, Switzerland and Italy. As a result I am familiar with scientific and engi-neering work in TJt;/ area of competence in many cotmtries and know most of the workers.
