U.S. NUCLEAR REGULATORY COMMISSION INSTRUCTIONS FOR THE

PREPARATION AND DISTRIBUTION OF MATERIAL STATUS REPORTS

DOE/NRC FORM 742- MATERIAL BALANCE REPORT AND 742C-

 PHYSICAL INVENTORY LISTING

I. INTRODUCTION

The U.S. Nuclear Regulatory Commission (NRC) and the U.S. Department of Energy

(DOE) jointly participate in the Nuclear Materials Management and Safeguards System

(NMMSS), utilizing common reporting forms to minimize the reporting burden upon

users of nuclear material required to provide nuclear materials data to one or both

agencies in accordance with prevailing regulations or contractual obligations, as is the

appropriate case. In this manner, the licensee1 is able to file one report and meet the

reporting requirements of both NRC and DOE, rather than having to file different

reports for each agency-required response. Compliance with specific reporting

requirements is monitored by the agency for which the specific data is required. 

A. Regulatory Authority

NRC regulations require each licensee who is authorized to possess at any one time

and location2 special nuclear material (SNM) in a quantity totaling more than 350 grams

of contained uranium-235, uranium-233, or plutonium, or any combination thereof, to

prepare and submit in computer readable format reports concerning SNM received,

produced, possessed, transferred, consumed, disposed of, or lost3. Reports are to be

made as of March 31 and September 30 of each year, or alternate dates if authorized

by the NRC, and filed within thirty (30) days after the end of the period covered by the

report. If licensees are reporting pursuant to 10 CFR 75, reports are to be dispatched

as soon as possible and in any event within thirty (30) days after the start of the

physical inventory taken as part of the licensee’s material accounting and control

procedures.

A separate DOE/NRC Form 742 shall be completed for each material type of SNM for

which a reportable quantity is possessed or a reportable inventory change has

occurred during the period. Reportable quantities are defined in NUREG/BR-0006.
NUREG/BR-0007, Rev. 3 2

Also, each licensee who is authorized to possess at any time or location, more than

1000 kilograms of source material or any combination thereof, must submit a statement

of foreign origin source material inventory. A DOE/NRC Form 742 may be used. 

Reports are to be made as of September 30 of each year and filed within 30 days after

the end of the period covered by the report, or as specified in Facility Attachments if the

licensee is reporting pursuant to the 10 CFR 75.

In addition to the DOE/NRC Form 742, licensees possessing DOE-owned SNM under a

Lease Agreement are required, by the DOE contract, to complete Form DOE 742A and

Form DOE 742B pursuant to the supplemental instructions issued by DOE. These

forms are not required for privately owned SNM.

B. Reporting/Distribution Requirements

Form 742 has three sections in addition to facility identification data in Blocks 1 through

5. Section A, “Material Accountability,” Lines 7 through 83, are to be used to report

material accountability data such as receipts, shipments, usage, losses, gains, etc. 

Section B, “Country Control Number Data,” is to be used to report the distribution of the

total inventory on hand by country of origin as defined in the instructions for completing

DOE/NRC Form 741. Section C, “Certification,” provides for the certification of all

entries on the Form.

Proprietary information must be included in all reporting forms when necessary to

provide an adequate response. An application to withhold such information from public

disclosure may be made, and would be disposed of, in accordance with the provisions

of 10 CFR 2.790. If any of this information is of particular sensitivity, a request may be

made that such information not be physically transmitted to the IAEA; such a request

must refer to, and must conform with 10 CFR 75.12.

The prescribed computer-readable format replaces the submittal of DOE/NRC Form

742 to NMMSS in paper form which had been previously required. However, paper

hard copies of the form should be provided to all interested parties.

If reporting enriched uranium (material type 20), enter the appropriate enrichment

level code in lieu of “20,” as follows:

Code Description

E1 Greater than normal but less than 5.00%

E2 5.00% or more, but less than 20.00%

E3 20.00% or more, but less than 80.00%

E4 80.00% or more

the isotope Pu238 if the decay is 0.1 gram or more. Pu238 decay is calculated

monthly using a decay factor of 0.000668 based on a half-life of 86.4 years. 

73. Fission and Transmutation - Enter the calculated quantities of SNM lost by

fission and transmutation in a reactor.

74. Normal Operational Losses/Measured Discards - Normal Operational Loss

(NOL)/Measured Discards (MD) is a loss of material determined by

measurement or by estimate on the basis of measurement, which, whether in the

form of solids, liquids, or gases, has been discarded. Facilities reporting

pursuant to 10 CFR 75 do not include transfers to burial facilities on this line but

should report such transfers on Line 51. For all other facilities include on this

line all material discarded, including material transferred to an authorized

recipient for disposal (a sub-schedule should be attached detailing transfers to 
9 NUREG/BR-0007, Rev. 3

burial facilities; such transfers should not be included on Line 51, “Shipments

Reported on DOE/NRC Form 741").

All material that leaves the inventory through this process must be accounted for

on a DOE/NRC Form 741. In order to account for these types of discards, the

following codes are to be used:

If the discard is to the atmosphere (A), a Form 741 will be prepared with the

shipper’s “RIS” entered in both the shipper’s and receiver’s block but with an “A”

appended in the receiver’s block.

Similarly, if the discard is to a lagoon or pond (L), append an “L” to the receiver’s

RIS; for a discard to the ground (G), append a “G”; if the material goes off the

inventory into a holding (H) area for later removal to a burial site, append an “H”

to the receiver’s RIS. When the material is eventually shipped to a burial site,

the transfer series on the Form 741 would show the shipper’s RIS with an “H”

appended and the appropriate “V” series RIS in the receiver’s block.

Remove discards from inventory only when the material has been disposed of

(a) by transfer to an authorized recipient or holding area as provided in the

regulations in 10 CFR 40 or 74; (b) as authorized pursuant to 10 CFR 20.302

(Commission approved disposal methods); (c) as provided in 10 CFR 20.303 or

10 CFR 20.304, applicable respectively to the disposal of licensed material by

release into sanitary sewerage systems or burial in soil, or in 10 CFR 20.106

(concentrations in effluents to unrestricted areas); or (d) as provided in

corresponding regulation of Agreement States.

75. Accidental Losses - Accidental loss is the irretrievable and inadvertent loss of a

known quantity of SNM or source material as the result of an operational

accident and which loss has been determined by measurement or by estimate

on the basis of measurement.

76. Approved Write Offs - Leave Blank

77. Inventory Difference - Inventory Difference (ID) is the difference between

physical inventory and book inventory after the book has been adjusted for all

receipts and removals.

80. Ending Inventory DOE Owned - Enter the ending inventory which is DOE owned

as of the end of the last day of the period covered by this report.

81. Ending Inventory Not DOE Owned - Enter the ending inventory which is not DOE

owned as of the last day of the period covered by this report.
NUREG/BR-0007, Rev. 3 10

82. Total - Enter the sums of Lines 41 through 81. The totals reported on this line

must agree with those on Line 40.

83. Bias Adjustment - The inventory difference bias adjustment is that quantity of

material which should be added to or subtracted from the inventory difference

quantity on Line 77 to produce the best estimate of an unbiased inventory

difference. The adjustment represents the algebraic summation of the impact of

measurement system biases on each component of the measured plant material

balance. Include on this line the sum of the bias adjustments for the inventory

difference for the current period. Any prior period adjustments should also be

included on this line. Do not include bias adjustments that have already been

applied to the source data in the material balance equation. (This line applies

only to those licensees subject to the requirements of 10 CFR 74.13.)

B. SECTION B - COUNTRY CONTROL NUMBER DATA

The total amount of nuclear material on hand as of the date of the report (amount on

Line 80 or 81 or the sum of Lines 80 and 81) must be accounted for by country control

number within material type.

The following entries, by column, are required:

1. Country Control Number - Enter the unique country control number for each

category of nuclear material, as defined in NUREG/BR-0006, “Instructions for

completing Nuclear Material Transaction Report, DOE/NRC Form 741.”

2. Element Weight - Enter the weight of the contained special nuclear material or

source material in the reporting units listed in Section A of Form-742.

3. Isotope Weight - Enter the isotope weight. If enriched uranium or U233, enter

weight to the nearest gram of U235 or U233, as appropriate. If plutonium, enter the

sum of Pu239 and Pu241 to the nearest gram. If Pu238, enter the weight of the

isotope Pu238 to the nearest 1/10 of a gram. For depleted uranium, enter the

isotope weight to the nearest kilogram. Make no entry for other source material.

4. Total Weight - Enter the totals for both Columns 2 and 3. These totals must

agree with the totals on Lines 80 or 81 or the sum of 80 and 81.
11 NUREG/BR-0007, Rev. 3

C. SECTION C - CERTIFICATION

Date, Signature, and Title Line - The report, if submitted as a hard copy, shall be

signed by an authorized representative of the licensee. Otherwise, enter the date and

title of the authorized representative submitting the report. Each licensee must

establish internal procedures that will ensure that the information provided in the report

is accurate and that the report has been prepared and issued only by the authorized

licensee personnel.

D. SECTION D - PREPARATION OF DOE/NRC FORM 742 IN COMPUTERREADABLE FORMAT

NMMSS Report D-24 provides instructions for preparing DOE/NRC Form 742 in

computer-readable format as required for submittal.

1. Automated Methods for Submitting Data to the NMMSS

a. Establishing an Electronic Connection with the NMMSS

A licensee may submit the DOE/NRC Form 742 electronically by

using a modem and a telephonic transfer. In order to establish an

electronic connection with the NMMSS, licensees must contact the

NMMSS security officer to request establishment of a connection

with the direct link. If the facility is a valid facility for the type of link

requested (classified or unclassified), the security officer will

provide the requester with the appropriate forms to complete.

Upon receipt of the completed forms, the security officer creates a

user ID and password and establishes an account for the facility. 

The user ID and password are then forwarded to the user facility

along with a password acknowledgment form. The licensee signs

the acknowledgment form and returns it to the security officer who,

upon receipt, activates the user ID and password. 

b. Handling techniques, format requirements, and data

submittals

DOE/NRC Form 742 should be submitted in computer-readable

format unless reporting per 10 CFR Part 40.64(b). NMMSS Report

D-24 provides additional instructions on handling techniques,

format requirements, and data submittals using diskettes.
NUREG/BR-0007, Rev. 3 12

c. Safeguards Management Software (SAMS)

The SAMS is a miniature version of the Nuclear Materials

Management and Safeguards System (NMMSS). This software

allows one to perform edit checks, generate various reports, import

and export transactions, material balance and inventory data. The

SAMS program with the appropriate formats and user prompts may

be obtained from the NMMSS Program Manager. 

d. New / Modified Methods of Transferring Electronic Data 

New or modified methods of transferring electronic DOE/NRC Form

742 data to NMMSS may be authorized by the NRC. Confirmation

of additional methods for the transfer of this data may be obtained

by contacting the NMMSS operator. 

2. Documentation and Distribution

The completed NRC/DOE Form 742, in computer readable format, should

be submitted to the NMMSS Operator. Confirm the address and

mechanism of providing data to NMMSS by calling the NMMSS Operator 

at 770-662-8110 prior to submitting data. Note that specific instructions

depend upon whether the Form 742 contains classified or unclassified

in an expanded level of detail is a DOE reporting requirement which also meets

inventory reporting requirements of NRC. The total of DOE-owned inventory on which
NUREG/BR-0007, Rev. 3 16

inventory data is reported must agree with the quantity entered on line 80, “Ending

Inventory DOE Owned,” on the DOE/NRC Form 742.

Submit the data as specified in Section II.D.

Reports filed under this section are to be submitted within thirty (30) days after the end

of the period covered by the report.

B. LICENSEES REPORTING UNDER 10 CFR PART 75

The instructions in this section apply only to facilities which have been notified by letter

from the NRC, as provided in 10 CFR 75.11, that they have been identified under the

US/IAEA Safeguards Agreement. Facilities who are required to submit INITIAL

inventory reports under 10 CFR 75.32, and a physical inventory is not performed, shall

prepare DOE/NRC Form 742 according to the instructions in II.A of these procedures

completing Items 1, 2, 3, 4, 5, 80, 81, and 82. The information in the initial inventory

report may be based upon the licensee’s book record. Facilities reporting under this

section will file Subsequent Material Balance Reports based upon a physical inventory

and are required to attach a completed DOE/NRC Form 742C, Physical Inventory

Listing (PIL). Such reports are required with respect to each physical inventory taken

as part of the material accounting and control procedures required by 10 CFR 75.21. 

Unless otherwise specified by license conditions, such reports shall be dispatched as

soon as possible and in any event within thirty (30) days after the start of the physical

inventory.

After completion of Form 742, prepare the submittal in computer-readable format

following the instructions in NMMSS Report D-24. 

The following numbered instructions correspond to the numbered blocks or lines to be

completed by licensees on the PIL.

1. Name and Address - Enter the name and address of the reporting facility.

2. DOE/NRC Form 740M Attached - Check the appropriate box to indicate whether

or not a DOE/NRC Form 740M is attached.

E3 20.00% or more, but less than 80.00%

E4 80.00% or more

17 NUREG/BR-0007, Rev. 3

6. Batch Data - The basic reporting entity is the batch, defined as:

“. . . a portion of nuclear material handled as a unit for accounting

purposes at a key measurement point and for which the composition and

quantity are defined by a single set of specifications or measurements. 

The nuclear material may be in bulk form or contained in a number of

separate items.”

A batch may have only one value for:

- batch name

- number of items

- composition/facility code

- key measurement point

- measurement basis

- scrap program

- owner code

In general, all of the data for one batch will be entered on one line of block 6 of

the DOE/NRC Form 742C. One exception would be if a single discrete item

contains more than one material (e.g., irradiated fuel containing both uranium

and plutonium); in such a case, a separate line should be used for the data for

each material, with all data common to all materials in the batch entered only on

the first line.

a. Material Type Code - Enter the applicable two-digit material type code for

each line entry. Codes for the various nuclear materials are as follows:

Code Description

10 Depleted Uranium

209 Enriched Uranium

50 Plutonium

70 U

233

81 Normal Uranium

83 Pu238

88 Thorium

89 Uranium in cascade
NUREG/BR-0007, Rev. 3 18

b. Composition/Facility Code - Enter the appropriate code from the list

developed during the formulation and negotiation of the Facility

Attachment.

c. Element Weight - Enter the weight of the contained special nuclear

material or source material in the same units as listed in Part II, Section A

of these procedures.

d. Isotope Weight - Enter the isotope weight. If enriched uranium or U233,

enter the weight to the nearest gram of U235 or U233, as appropriate. If

plutonium, enter the sum of Pu239 and Pu241 to the nearest gram. If Pu238,

enter the weight of the isotope Pu238 to the nearest 1/10 of a gram. For

depleted uranium, enter the U235 isotope weight to the nearest kilogram. 

Make no entry for other source material.

e. Project Number - For DOE-owned nuclear material, except lease or loan

material, a project number is required for all entries. An entry shall be

made for each active project number by material type code, showing the

quantities of nuclear material assigned to the project number.

f. Scrap Program - Refer to the DOE Manual M 474.1-2 series for reporting

instructions.

g. Weight Percent Isotope - Enter the weight percent of the isotope U235 if

uranium enriched or depleted in U235. If plutonium, enter the weight

percent of the isotope Pu240. If Pu238, enter the weight percent of the

isotope Pu238. Report weight percent to at least two, but not more than

four, decimal places, depending upon the accuracy yielded by the

measurement method employed. Example of weight percent isotope to

four decimal places: XX.XXXX%. For U233, enter the parts per million of

U

232. Does not apply for normal uranium or thorium. Use separate lines

to report material of different enrichments.

defined in Line 6 above. If the batch is a discrete item with a unique

identifying serial number or name (e.g., a fuel assembly, sealed source,

or UF6 cylinder), enter the identification number or name (up to a

maximum of 16 characters). If the batch is composed of bulk material or a

number of items, enter any alphanumeric identifier (of 16 characters or

less). Note that the same batch name must not appear twice in the same

report.

k. Number of Items - If the batch is composed of a number of discrete items,

enter the number of items. If the batch is bulk material, or generally

where the number of items is not meaningful, enter zero. If more than one

line is used to report data on the batch, the number of data items should

be repeated on each line.

l. Key Measurement Point - Enter the code for the appropriate inventory key

measurement point, as specified in the Facility Attachment or Transitional
