“... the owner or operator of any civilian nuclear

power reactor shall report to the Secretary (of Energy), acting through the Administrator of the Energy

Information Administration, for activities of the

previous fiscal year

(1) the country of origin and the seller of any

uranium or enriched uranium purchased or imported into the United States either directly or

indirectly by such owner or operator; and

(2) the country of origin and the seller of any

enrichment services purchased by such owner

or operator. ”

This information is required to be made available to the

Congress annually. Data reported by domestic nuclear

utility companies in their responses to the 1994 through

1995 “Uranium Industry Annual Survey,” Form

EIA–858, Schedule B, “Uranium Marketing Activities,” are provided in response to the requirements in the

Uranium Purchases Report 1995

Uranium Purchases by U.S. Utilities

During 1995, the owners and operators of U.S. civilian

nuclear electric generating units took delivery of 43.4

million pounds U3O8 equivalent (U3O8e) from suppliers (Table 1). The 33 firms that supplied the uranium to

the utilities are shown in the following list. Seventeen

of the 33 firms (designated with an asterisk) made deliveries under new purchase contracts in 1995.

Of the 43.4 million pounds delivered to U.S. utilities in

1995, natural uranium (U3O8 and UF6) accounted for 98

percent and enriched uranium accounted for 2 percent

(Table 1). The average price for the total deliveries was

$11.25 per pound. The primary origin for the uranium

delivered to U.S. utilities was Canada, followed by uranium from Russia and the United States. Foreign purchases accounted for 21.1 million pounds or 49 percent

of total deliveries to utilities, compared with 41 percent

in 1994 (Table 2). The domestic– and foreign–origin

uranium that was purchased from U.S.–based companies are reported as domestic purchases.

Enrichment Services Purchased by

U.S. Utilities

The amount of separative work units (SWU) purchased

by U.S. utilities under enrichment service contracts that

were delivered in 1995 was 9.5 million SWU (Table 3).

The 8 firms that were reported as the sellers of enrichment services for these SWU deliveries in 1995 are

shown in the following list.

Enrichment Service Sellers to U.S. Utilities

COGEMA, Inc.

Global Nuclear Supply Service, Ltd.

Nuexco Trading Corporation

NUKEM, Inc.

UG U.S.A., Inc.

United States Enrichment Corporation (USEC)

Urenco

Wolfco Trading, Inc.

Seventy–one percent of the enrichment was conducted

at U.S. enrichment plants under United States Enrichment Corporation operation. The remaining enrichment for U.S. utilities was performed in France, Germany, the Netherlands, Russia, and the United Kingdom

(Table 3).

Uranium Enrichment Feed

In 1995, enrichment feed deliveries by U.S. utilities totaled 44.3 million pounds U3O8e shipped to both domestic and foreign enrichment suppliers, 18 percent

above the 1994 level (Table 4). Deliveries consisted of

21 percent of U.S.–origin and 79 percent of foreign–origin uranium. Utility enrichment feed deliveries to U.S.

enrichers in 1995 totaled 33.9 million pounds (77 percent of total deliveries). Feed deliveries to non–U.S. enrichers in 1995 totaled 10.4 million pounds (Table 4).

Appendix

Survey Methodology

Survey Design

Form EIA–858, “Uranium Industry Annual Survey,”

was used to collect information from all companies

known or believed to have been involved in the U.S. uranium industry during 1995. Included in this survey are

domestic utilities that own and/or operate nuclear power

reactors. The 1995 survey form was mailed to respondents in December 1995, and was due back in March

1996. Respondents to the “Uranium Industry Annual

Survey” were asked to provide data current to the end of

1995 about their Uranium Raw Materials Activities

(Schedule A) and Uranium Marketing Activities

(Schedule B).

In particular, Schedule B covers: uranium transaction

parameters including name of the other party; type of

transaction; uranium materials covered; origin for the

uranium materials; conversion and enrichment services,

delivery destination; importation and exportation; pricing mechanism; schedule of uranium deliveries with

corresponding prices; uranium inventories; materials

shipped for enrichment; projected enrichment feed deliveries; unfilled market requirements; and the amount

of enrichment services and loaded fuel assemblies by

U.S. utilities. Quantities of uranium reported are as

equivalent U3O8 rounded to the nearest thousand

pounds.

The data collected on Form EIA–858 are subject to several sources of error. These sources are: (1) coverage

(the respondent frame might not be complete or, on the

other hand, there might be double counting); (2) nonresponse (all units surveyed might not respond or might

not provide all the information requested); (3) respondents (respondents might commit errors in reporting the

data); (4) processing (the data collection agency might

omit or incorrectly transcribe a submission); (5) concept

(the data collection elements might not measure the

items they were intended to measure); and (6) adjustments (errors might be made in estimating values for

missing data).

Because the “Uranium Industry Annual Survey” is a

universe survey rather than a sample survey, sampling

errors do not affect the data provided in this report. Although it is not possible to present estimates of non–

sampling error, precautionary steps were taken at each

stage of the survey design and operation to minimize the

possible occurrence of these errors. These steps are described below, and the errors they were designed to

minimize are named (in parenthesis).

Survey Universe/Frame (Coverage

Errors)

The survey universe includes all nuclear utilities involved in the U.S. uranium industry. The criteria for responding to Schedule B are firms that during 1995: (1)

held existing contracts covering the sale, purchase, exchange, loan, loan repayment, or custody of uranium or

entered into similar new contracts; (2) held inventories

of uranium in any form excluding reactor–inserted, fabricated fuel; (3) maintained a uranium–inventory

policy; (4) made actual deliveries of uranium feed materials to any enrichment supplier; and/or (5) purchased

enrichment services.

The respondent list used for the Form EIA–858 survey

was developed from a frame of all establishments

known to meet the selection criteria. The frame of potential respondents was compiled from previous surveys

and from information in the public domain. As it specifically relates to Schedule B, the frame was intended to

cover the following: all utilities owning nuclear–fueled

generating stations, fuel converters and fabricators, and

utilities with whole or partial ownership in operating or

planned uranium–fueled power plants.

Survey Procedures (Nonresponse)

The survey forms were sent by first class mail to ensure

their receipt only by the proper respondent organization.

If the U.S. Postal Service was unable to deliver the survey form, the corrected address was obtained where

possible. All nuclear utilities currently conducting business in the U.S. uranium industry were contacted during

this survey.

The Form EIA–858 is a self–administered questionnaire

requesting data about many areas of company operations. The scope of the questions is necessarily broad,

and self–reporting of company–specific data are required.
8 Energy Information Administration/Uranium Purchases Report 1995

Cooperation from industry on the 1995 survey was

good. A large number of respondents returned the completed form within the specified deadline. Those that

had not responded by the due dates were telephoned to

encourage submission of the forms, and those calls resulted in the submission of most of the remaining forms.

Subsequently, telephone calls were made to obtain

forms not yet submitted. In some instances, company

data were modified/collected through telephone conversations made to clarify items reported/omitted on

their submissions.

Data Editing, Analysis, and Processing (Respondent and Processing Errors)

The survey forms were logged in and reviewed by

agency personnel prior to data entry into the Uranium

Industry Annual System, an automated data base containing all current and historical data from each company’s submission. The data base is maintained on the EIA

computer facility in Washington, D.C. After entry into

the data base, a copy of each Schedule B was distributed

to the EIA’s Analysis and Systems Division analyst for

review and approval. The submissions were checked

for internal consistency, and the reported data were

compared with previous collections of similar data. After reviewing the submissions, the analyst consulted

with the reporting company, as needed, to resolve data

problems and to confirm any corrections of the data.

Data areas that were reviewed and the corrections that

were made differed from company to company. Most

represented differing interpretations of the data item

definitions. Computer edits were also used to identify

keypunch errors, out–of–range values, and unlikely data

combinations. These edits either were corrected to represent the data reported on the submissions or were

changed only after confirming the corrected values by

telephone conversations with company representatives.

Data coding and entry errors were eliminated by proofing data after entry. All changes to data were documented.

Response Rates

Schedule B of Form EIA–858 was mailed to 87 firms.

Overall, 100 percent of the firms responded to EIA with

the data as requested for the survey sections as applicable to individual firms.

Missing Data

Omissions of data identified during the prescreening

and editing of the data fell into two categories: (1) data

that were withheld because of contractual constraints, or

(2) because particular data were unknown. Respondents

were contacted regarding omissions to verify that the

data could not be reported. Only confirmed company

data are contained in the data base and included in this

report.

Nondisclosure of Data

To protect the confidentiality of individual respondents’

data, a policy was implemented to ensure that the reporting of survey data in this report would not associate

those data with a particular company. This policy is in

compliance with EIA Standard No. 88–05–06, “Nondisclosure of Company Identifiable Data in Aggregate

Cells.” In tables where the nonzero value of a cell is

composed of data from fewer than three companies or

if a single company dominates a table–cell value so that

the reporting of the value would lead to identification of

a company’s data, then the EIA classifies the cell value

as “sensitive,” and the cell value is withheld (“W”) from

the report. Within a table with a sensitive cell value, selected values in other cells of the table are also withheld,

as necessary, so that the sensitive cell value cannot be

computed using the values in published cells.

Glossary

Domestic: Domestic means within the 50 States, District of Columbia, Puerto Rico, the Virgin Islands,

Guam, and other U.S. possessions. The word “domestic” is used also in conjunction with data and information that are compiled to characterize a particular segment or aspect of the uranium industry in the United

States.

Domestic purchase: A uranium purchase from a firm

located in the United States.

Enrichment Feed Deliveries: Uranium that is shipped

under contract to a supplier of enrichment services for

use in preparing enriched uranium product to a specified

235U concentration and that ultimately will be used as

fuel in a nuclear reactor.

Enrichment Services: See Separative Work Units

(SWU).

Foreign purchase: A uranium purchase of foreign–origin uranium from a firm located outside the United

States.

Nuclear reactor: An apparatus in which a nuclear fission reaction, i.e., the splitting of atomic nuclei to release heat energy, can be initiated, controlled, and sustained at a specific rate. A reactor includes fuel

(fissionable material), moderating materials to control

the rate of fissioning, a heavy–walled pressure vessel to

house reactor components, shielding to protect personnel, a system to conduct heat away from the reactor, and

instrumentation for monitoring and controlling the reactor’s systems.

Prices of Uranium: The quantity–weighted average of

the prices paid for deliveries of uranium as reported on

the Form EIA–858, “Uranium Industry Annual Survey,”

as purchases of either U3O8, natural UF6, or enriched

uranium.

Purchases of Uranium: The amount of uranium material that is delivered during a survey year as reported on

the Form EIA–858, “Uranium Industry Annual Survey”

(UIAS), as purchases of either U3O8, natural UF6, or enriched UF6. The amount of uranium material under other types of contracts reported on the UIAS, i.e., loans

and exchanges, is excluded.

Separative Work Units (SWU): The standard measure

of enrichment services. The effort expended in separating a mass F of feed of assay xf into a mass P of product

assay xp and waste of mass W and assay xw is expressed

in terms of the number of separative work units needed,

given by the expression SWU = WV(xw) + PV(xp) –

FV(xf), where V(x) is the “value function,” defined as

V(x) = (1 – 2x) ln((1 – x)/x).

Uranium: A heavy, naturally radioactive, metallic element (atomic number 92). Its two principally occurring

isotopes are 235U and 238U. The isotope 235U is indispensable to the nuclear industry because it is the only

isotope existing in nature to any appreciable extent that

is fissionable by thermal neutrons. The isotope 238U is

also important because it absorbs neutrons to produce a

radioactive isotope that subsequently decays to the isotope 239Pu, which also is fissionable by thermal neutrons. 

 Concentrate: A yellow or brown powder produced from naturally occurring uranium minerals as

a result of milling uranium ore or processing uranium–bearing solutions. Synonymous with yellowcake, U3O8, or uranium oxide.

 Enriched Uranium: Uranium in which the

235U isotope concentration has been increased to

greater than the 0.711 percent 235U (by weight)

present in natural uranium.

 Uranium Hexafluoride (UF6): A white solid

obtained by chemical treatment of U3O8 which

forms a vapor at temperatures above 56 degrees

Centigrade. UF6 is the form or uranium required for

the enrichment process.

Uranium Oxide: Uranium concentrate or yellowcake.

Abbreviated as U3O8.
