APPENDIX "D"

MEASUREMENTS OF IRRADIATED REACTOR MATERIAL

1. Scope

This Appendix prescribes the general methods and procedures for inspection, weighing, sampling, assaying and measuring (hereinafter collectively referred to as "measurements") of irradiated reactor material and recovered uranium and plutonium products in connection with this contract. This Appendix will be supplemented by the detailed procedures submitted by the Contractor to the Commission for approval in accordance with Article XXXI B.

The written procedures to be developed by the Contractor in accordance with Article XXXI B. shall prescribe the detailed measurement methods and procedures to be used by the Contractor, the Commission and umpires. Such measurement methods and procedures shall be used by the Contractor, the Commission and umpires for measurement and analysis of samples taken in accordance with this Appendix.

2. Receipt of Irradiated Reactor Materials by the Contractor

Upon receipt of irradiated reactor materials at the Plant, the Contractor shall perform inspections, piece count and weighings as necessary to certify that it has received the shipment described in the appropriate Commission shipping form, and that no significant discrepancy in weight or description exists. Any significant discrepancy in weight or description which is found during this preliminary examination (which examination shall include the correlation of the descriptions and weights in the appropriate Commission shipping form and in the Specific Material Description as contained in Appendix A, Part C), shall be reported to the Contracting Officer within 6 days from the time of delivery. This preliminary physical examination shall serve as the basis for the completion of the provisional Commission shipping form; however, all discrepancies must be resolved prior to the completion of this form and prior to any chemical processing. The completion of the provisional Commission shipping form by the Contractor shall not constitute a verification of the uranium or plutonium quantities or isotopic content designated by the shipper.

3. Method of Obtaining Input Measurements

a.

Upon completion of dissolution of irradiated reactor materials, the Contractor shall determine the total weight or volume of

each batch of dissolver solution, mix each batch to achieve homo-
geneity, and take three representative samples.

The Contractor shall measure the volume of each dissolver batch
and determine the specific gravity of such solution.

The Contractor shall analyze each of two samples of the dissolver
solution for specific gravity, total uranium, and, where applic-
able, the plutonium content and shall make portions of these samples
available to the Commission upon specific request of the Commission,
and shall hold a third sample in reserve for use as an umpire sample.
The Contractor shall sample each dissolver batch and shall analyze
for the U-235 content and, where applicable, plutonium (Pu-239 and
Pu-241) isotopic content.

The weight of uranium and plutonium, where applicable, in the dis-
solver hulls shall be determined by the Contractor.

Waste Stream Measurements

All waste streams, including but not limited to dissolver hulls, solvent extraction raffinates, evaporator condensate, and solvent treatment solutions, will be monitored prior to discharge to establish the amount of uranium and, where applicable, plutonium in each of these waste streams.

5. Method of Obtaining Recovered Product Measurements

a.

The Contractor shall determine the total weight of each batch of
uranium or plutonium product collected, shall mix each batch to
achieve homogeneity, and shall take three representative samples
of each batch of uranium or plutonium product solution.

b. The Contractor shall analyze each of two samples of each uranium product batch for total uranium and the uranium-235 content of the uranium and shall analyze each of two samples of each plutonium product batch for total plutonium and Pu-239 and Pu-241 content, shall make a portion of these samples of each respective product batch available to the Commission, and shall hold a third sample of each respective product batch in reserve for use as an umpire sample.

6. Specifications for Recovered Uranium and Plutonium

The Contractor shall analyze recovered uranium and plutonium to determine conformance of the products to the specifications set forth in Appendix "C' These analyses shall be performed on a portion of each of the Contractor samples described in Section 5.

7. Design Criteria

All vessels used for batch measurement shall be equipped with
(1) mechanisms for efficient agitation, (2) volume measurement
instrumentation, (3) specific gravity instrumentation, (4) tem-
perature sensing instrumentation, and (5) samplers. These
vessels should be sufficiently rigid and of as uniform cross
section as possible throughout their entire height to facilitate
accurate calibration. The vessels should be equipped with pip-
ing from service areas so that, if the need arises, the vessels
may be recalibrated after the plant is in operation. Batch
measurement vessels shall be recalibrated when changes to or
substitutions of installed equipment which could have affected
calibration are made.

Waste streams shall be equipped with flow measurement instrumentation and proportional samplers, or hold tanks.

Cells containing processing equipment used prior to completion of input measurements, including the Process Mechanical Cell, shall be equipped with spraydown headers or other equipment for washdown to recover process spills and leaks and to provide for cleanout between individual processing lots. Such cells shall be equipped with sumps and sloping floors so that spills, washdowns and leaks will drain into the sumps.

Provision shall be made for collection of sump wastes, to permit volume measurement, agitation, and sampling before disposal.

PLANT DATA FOR PUBLIC DISSEMINATION; OPERATING REPORTS

The three types of cost data to be disseminated to the general public concerning the Plant are:

1. Owner's price breakdown by functional units;

2. Bechtel Corporation's detailed cost breakdown for certain

3.

process steps; and

Detailed back-up operating data for the Plant.

Annex "A" is representative of the Owner's Price Breakdown.

Annex "B" is representative of the Process Step Cost Breakdown. The various cost categories are defined as follows:

1. Materials Purchase price of materials, whole pieces of
equipment, and total price of subcontracts where the work
involved is pursuant to producing a finished piece of equip-
ment or material item.

2.

Installation

All direct labor costs resulting from hourly time spent on the job with normal standby use charges for equipment required during installation and subcontract costs where the work involved is primarily labor (e.g., excavation, installation contracts).

3. Indirect

Field expense, overhead, profit and/or fee, unique labor costs incurred as a result of the physical location of the site at a distance from towns and cities (isolation pay), costs incurred due to strikes, premium pay, for overtime, vacation allowance, and other unallocated direct or indirect costs. Distribution of costs bearing directly on labor such as isolation pay, vacation pay, etc., should be in proportion to direct labor costs; those bearing directly on material such as warehousing and purchasing, should be in proportion to material costs; all others, in direct proportion to total of labor and materials.

The various process steps for which this type of cost breakdown is required are listed in Annex "C".

Annex "D" sets forth certain operating reports which the Contractor shall furnish to the Commission.
