SUBJECT:

SUMMARY

OF INFCE 0VERVIEW REPORT

'We thought you would find useful a summary of the INFCE Overview report.

Since its issuance, you have been asked what the implications of its conclusions will be for Commission positions on domestic ' reprocessing and recycle.

In this connection, many of those who have raised this issue have mischaracterized the results of INFCE, i.e., have asserted that the United States agrees with those statements in the INFCE Reports that may be interpreted as favorable to re-processing and recycle.

We.have prepared for your use the following draft statenent, which could be used to respond to such assertions.

In preparing it, we drew on the INFCE Overview Report itself, on Ambassador Smith's statement at the Final Plenary Conference in February, and on the NASAP Report " Nuclear Proliferation and Civilian Nuclear

' Power":

It must be emphasized that the final INFCE individual working group reports are products of consensus and reflect a wide range of judg-ments and viewpoints. As Ambassador Smith observed in his Statement to the Final INFCE Plenary Conference, "I do not wish to imply that the United States, or any other nation, agrees with every statement in the report". Ambassador Smith went on to note that the United States continues to believe that it "can prudently defer moves implying' a comitment to a ' plutonium economy'".

With respect to reprocessing, the Evaluation concluded that spent fuel can be safely stored on an interim or long-term basis, that terminal disposal without reprocessing appears to be a realistic option for either ' economic or non-proliferation reasons, and that the economic advantage of plutonium recycle in light water reactors will be, at best, small.

To The Commissien 2-c The foregoing conclusions are not 'at variance with those contained in the Reportof the Nonproliferation Alternative Systens Assessment Program, entitled '" Nuclear. Proliferation and Civilian Nuclear Power", prepared by the US Department of Energy. That Report states that "the light-water reactor fuel cycle with spent fuel discharged to interim storage does.not involve directly weapons-usable material in any part of the fuel cycle and is c more proliferation resistant nuclear power fuel cycle than any other fuel cycles which involve highly enriched uranium or pure plutonium."

Elsewhere, the NASAP Report notes that " Recycle systems would be

~

vulnerable to a wide range of threats, whereas current once-through fuel cycles are susceptable to only the most sophisticated threats".

Finally, the following sumary tracks the structure of the Overview Report itself.

AVAILABILITY OF RESOURCES AND FUEL CYCLE SERVICES IN THE LIGHT OF PROJECTIONS OF NUCLEAR POWER DEMAND I-A.

Nuclear Power Projections The high-low nuclear generating capacity projections for world outside of communist areas (WDCA) countries were based on national estimates by IAEA member countries and various studies done by the Nuclear Energy Agency (DECD) and the International Energy Agency. Through the year 2000, these high-low projections for WDCA are as follou i*

1985 245-274GW(e) 1990 373-462GW(e) 1995 550-770 GW(e) 2000 850-1200GW(e)

I-B,.

Reactor Strategies Requirements for nuclear fuel, heavy water and associated services over the next 50 years will depend not only on nuclear growth projections but also on the types of reactors in operation.

Only reactor types and technologies that are presently available, e.g., once-through 1ight-water and heavy water reactor fuel cycles, or likely to be

~

available in the reasonably near future, e.g., large scale fast-breeder reactors, were used in calculating demand for fuel and fuel cycle services.

+

Using a serias of illustrative " mixed strategies" based on combined deploy-ment of LWRs, HWRs and FBRs, the following plausible " range of demand was determined:

approximately 117,000-208,000 short tons of U30 per annum in the g

year 2000 to approximately #7,500-559,000 short tons of U308 per annum.

  • Comparative WOCA projections done-by the DOE's Energy Information Administration are considerably lower:

(As of July 1979) 1985 216-247 GW 1990 305-376 GW 1995 418-552 GW e 2000 550-750 GW e) r e

I-B-2. -. Uranium Ava11 ability The' supply of uranium over the period up to 2025 will come primarily from deposits cf a. type that is either currently being exploited or that could be exploited under current technological and economic conditions. Based on a Decenber 1978 NEA/IAEA study, there is also significant potential for the discovery of conventional resources in addition to those in the " Estimated Additional Resources" category.

Hbwever, with respect.to these so-called " speculative Resources," they rray not be discovered' and brought into production until af ter the first quarter of the twenty-first century.

Uraniu2 pro'du~ction~ c., ability was about 50,700 short tons of U308 per annum in 1~9 Per annum by 1980, and to 117,000 It could be increased to 63,700 short tons of U308 short tons of U308 per annum by 1985. A peak le' vel of production of approximately 143,000-156,000 short tons of U30 per annum is 'potentially achievable in the 1990's 8

under optimum conditions. Production would subsequently decline to 26,000 short

~

tons of U30 Per annum by 2025 as known deposits were depleted.

8 The achievement of adequate levels of uranium production also depends largely on political ad market climates, availability of manpower and equipment, and the resolution of environmental and regulatory uncertainties.

I-B-5.

Comparisons of uranium supply and demand On the basis of Working Group I comparisons of uranium supply and demand, additional sources of production are likely to be needed by, possibly, the early 1990's. The bulk-of the required new production will have to be supported by new discoveries.

The urantum industry, with the necessary exploration and investment, should not experience undue difficulty in meeting requirements up to the year 2000, n

h-s

~=i.

_3-Such factors as the use of various reactor strategies, market continuity and

-stability, increased uranium ore exploration and improved extraction methods, and

. improvements in LWR technology, will all affect the uranium supply and demand pr2jections presented by INFCE.

I-C. ' Fuel Cycle Services

+

Present enrichment capacities and those under construction would cover projected needs until 1990 while the addition of planned capacities would cover needs until af ter 1995.

Beyond 2000, the capacity that would have to be installed is not s,een as 'a major problem.

However, the situation with respect to the availability of reprocessing services is

-different. Reprocessing capacity by 2000 is expected to be 9,000-10,000 t U0 I"*

2 The spent fuel management concepts chosen by cou'ntries and the availability of storage space will affect future reprocessing capacity. (NOTE:

It is pointed out that the largest proportion of spent fuel expected to accumulate from 1980-1990 will be LWR fuel in countries that have defer-ed their decisions.

IMPACTS II-A-1. and 2. - Technical Feasibility of Current and Advanced Fuel Cycle Activities

_Efrichment: The technical viability of gaseous diffusion and ultracentrifugation'is well established.

Other technologies, e.g., aerodynamic, chemical laser, are less

. advanced butoffer good prospects for future industrial application.

Storage and transport of spent fuel:

National interpretations of spent fuel management concepts are cepen' ent on current d

s:ctal, economic, regulatory and political conditions and energy needs prevailing in a country at a given time.

However, the national policies of one country can have e

storage might be an alternative for exwnded interim storage.

~

-S-e l Waste Management and Disposal _: Methods fo-management and cisposal of low-:and medfur ' vel wastes are operational and well-proven.

Fast Breeder Cycles:

Deployment of a significant number of FBRs using current technology and oxide fuels would be feasible by 2000.

Thorium / uranium recycle fuel cycles and other ady' nced reactor systems:

Commercial a

deployment probably could not be available until after the year 2000.

II-B. ' Economic Considerations Economic aspectr of fuel cycle options as well as countries' energy strategy considerations were examined.

Af ter analyzing once-through and plutonium 2 recycle HWRs and LWRs, and FBRs in the above context, Working Group 4 concluded the no one fuel cycle can be said to have an economic advantage in all cases.

mnomic advantages may exist in relation to specific energy strategies chosen by i

.vidual countries.

Reprocessing in itself is important because it is an essential preliminary to many of the possible fuel cycles.

The economic arguments for reprocessing depends on the price of uranium 'and on the subsequent use that is made of the separated plutonium and uranium.

If it is recycled in light water reactors, then the economic' advantage is not likely to be large. However, sane countries neverthelass see it as a positis: contribution to energy independence and assurance of supply.

On the other haua, if the capital costs and the fuel cycle costs of fast reactors can be brought down sufficiently, then the economic and assucance of supply advantage of fast reactor recycle could be considerable.

Most countries planning to use plutonium therefore consider mainly its.use in fast reactors.

s www-

6-in addition, the economic considerations affecting breeder deployment will vary from country to CduntTy, depeiiding on what alternative sources for long-term assurance of energy are available for that given country.

II-C.

Envirorment, Health and. Safety

- Although an assessment of environmental, heal cnd safety issues with respect to various fuel cycle optior was not a primary task assigned to INFCE, these issues were considered in all of the W. eking Groups.

~~

The most far-reaching assessment of environmental and health and safety impacts.was perfo'med by Working Group 7, in the context of '. coking at all waste arising from r

seven fuel cycles'. The' Working Group concluded that the difference in these types of impacts of waste management and disposal among the fuel cycles examined does not constitute a decisive factor in the choice among them.

Specifically, the FBR cycle compared favorably, from an environmental impact standpoint, to the 1.WR cycle.

It was further concluded that reprocessing, mix.ed oxide fuel fabrication, plutonium-handling and recycle can all be carried out in c.onformity with the International CoNission on Radi, jical Protection reconmendations.

III. NON-PROLIFERATION ASPECTS INFCE's concern in this regard was with the technical aspects of possible misuse of the nuclear fuel cycle in implementing a country's decision to construct nucicar weapons. Those points in the nuclear fuel cycle that are sensitive frcza toe point of view of proliferati.n were identified, taking into account that a number of technical and institutional measures have been proposed or are under development that could reduce the risk of proliferation from all fuel. cycles.

" a-III-A. Sensitive Points in the Nuclear Fuel Cycles, Fresh fuel:

For low-enriched uranium cycles (LWRs, HWRs, ans HTRs) and medium-cnriched cycles, uranium in the fresh fuel itself would not be weapons-usable without further enrichment.

Uranium enrichment facilities: Most facilities produce low-enriched fuel -- prolifcration risk lies in possible diversion for use in other facilities for production of weapons-useble materials.

Modifications of enrichment plants producing LEU to HEU are extrer.nly difficult to achieve.

Reactors:

In general, the phase when the fuel ele ents are.in an operating reactor was concidered a less importent area than the other parts of the fuel cycle from the proliferation point of view.

On the whole, it appears that an adequate degree 'of proliferation resistance can be attained, at least in the short and medium term, with present thermal reactors in the once-through mode, provided that appropriate safe-guards are appiied to carichment, fuel fabrication and irradiated fuel storage facilities.

In this same context Working Group 5 estimates that'the diversion risks encountered in the various stages of the FBR fuel cycle present no greater difficulties than in the case of the LWR with the U-Pu cycle, or even in the case of'the once-through cycle, in the long term.

Spen't Fuel Storage: The high radiation level inherent in spent fuel is.an important factor against proliferation.

{

' Working Group 6 determined that the existing legal and institutional framework for spent fuel' managenent is adequate to minimize the risk of proliferation.

However, there is no international legal framework to provide states with assurances of acces, to or management o'f their spent fuel.

1

.g.

Reprc'..s' sing, Plutonium Storage and Mixed Oxide Fuel Fabrication:

In the event y.

that reprocessing develops, it will be necessary to adopt the best technical,

-safeguards and institutional measures to increase the protection of such material against diversion.

Ik addition,~ it is noted that the use of commercial-grade plutonium is an unattractive route to the manufacture of nuclear weapons as compared with weapons-grade plutonium produced by a dedicated program.

However, it should be noted that the United States government has declared that comercial-grade plutonium can be used for weapons,

.pu'rposes and that this statement has not been challenged by other nuclear-weapons states.

Waste and Spent Fuel Disposal: Waste disposal was not regarded as a sensitive step in,the fuel cycle.

IV.. MAKING NUCLEAR ENERGY WIDELY AVAILABLE TO MEET THE WORLD'S ENERGY REOUIREMENTS Working Group 3 investigated assurances of long-tem supply of technologi, fuel and.

heavy water and services in the interest of national needs consistent. with non-proliferation.

IV-A.

Commercial Markets The following items were' identified as means of achieving assurance of supply and

~dcmand of uranium:

l.

negotiat' ion of long-term comercial contracts, with built-in flexibility to pemit adjustment and appropriate sharing of burdens and risks of market fluctuet w..; between supplier and contumer:

s

s.c 9.-

3; p'

i 2v. the existence and maintenance of a sound market for spot transactions in

. order to ' cope with short-term fluctuations in supply and demand; 3.

diversification of supply, i.e., _new suppliers of enrichment services will enter the market in the 1980's and beyond;

'4.

greater financial participation by consumers on the supply side, e.g.,

_ capital or management participation, loans or advance payments.

The following short-or medium-term back-up arrangemerits were also examined:

1.

Uranium Emergency Safety Network, which could build on existing ad hoc

~

ar,rangements among utilities, primarily in Europe and t.he US, for swapping -

or loans of fuel for a limited period of time out of existing inventories; and 2.

International Nuclear Fuel Bank, which would be made up of supplier and consumer states and would itself hold a stockpile of natural and low-enriched

)

uranium or' claims to such uranium. These assets could be made available to a consumer state whose supplies were interrupted by a contract default that was not the result of a breach of its ncn-proliferations undertakings.

IV-B.

Government Intervention Alth'ough to date, few actual interruptions of fsupply have occurred as a result of government intervention,(e.g., unilateral changes in agreed conditinr.s of supply),if uncertainties about possible supply interruptions continue, the orderly development' of nuclear power programs would be affected.

It was generally accepted that more uniform, consistent and predictable application of national export and import controls by each supplier and consumer country, in accordance with inore concrete criteria, would go a long way to mitigate uncertainties and thus strengthen assurances of supply.

i e

a n

c'ir,

,.e JAlso,;the potential for arbitrary exercise of prior' consent causes concern to consumer countries. Where a supplier country has a right of prior consent to retransfer of

. reprocessing, the criteria for its exercise should be established, to the extent possible, before long-term fuel supply contracts are concluded or, for short-term contracts, before fuel is committed to nuclear reactors.

Various international and bilateral mechanisms and other common approaches, are suggested for updating non-proliferation undertakings and conditions when recessary.

(Seepp.36-37).

V.

MINIMIZING THE DANGER OF THE PROLIFERATION OF NUCLEAR WEAPONS The following familiar technical measures were identified and described as pos'sible means of minimizing the danger of misuse of fuel cycle facilities:

1) co-location;
2) co-conversion;
3) co-processing;

- 4) denaturing; 5) pre-irradiation; 6) spiking;

7) partial processing; 8) physical barriers;
9) use of lower enrichment for research reactor fuels; and 10) improved IAEA and other bilateral safeguards In summary it was concluded that technical measures have a powerful influence on reducing the risk of theft, but only a limited influence on reducing the risk of proliferation.

It was also judged that safeguards measures are more important than the technical measures.

(

VI.

INSTITUTIONAL' ARRANGEMENTS P tentially more important than technical measures, in both minimizing proliferation Hsks 'and contributing to assurance of supply are institutional measures.

In

. general, it was deemed desirable that the evolution of institutional arrangements should move towards multinational ventures and could eventually result in the development of regional nuclear fuel cycle centers.

Among those institutional arrangenents discussed are;

1) multinational enrichment and reprocessing facilities; 2) the' International Nuclear Fuel Authority (the nature of[which was not yet clear);

3)' international storage of plutonium; and 4) iniarnational management of spent fuel O
