HISTORICAL PERSPECTIVE obel Prize laureate Enrico Fermi led the team of scientists who achieved the first self-sustaining chain reaction at the University of Chicago on December 2, 1942.

Chicago Pile 1- the first nuclear reactor - confirmed the theory that enormous amounts of energy could be generated and controlled by nuclear fission.

Fermi and other physicists were also aware that it was theoretically possible to go a step beyond the fissioning process and actually breed more fuel than was consumed in a reactor.

Over 99 percent of naturally occurring uranium consists of non-fissionable Uranium 238. Only seven-tenths of one percent of the ore is fissionable uranium. During the fissioning process, two to three neutrons are released. In the breeder, one of these keeps the chain reaction going, while the other neutrons are captured to breed new fuel by turning non-fissionable Uranium 238 into fuel that is fissionable - Plutonium 239.

The significance of this is the vast energy potential created by breeding.

Fast Flux Test Facility at Hanford, Washington Fermi was enthused about the prospects of the breeder and predicted in 1945 that the "country which first develops a breeder reac-o tor will have a great competitive advantage in atomic energy."

the Clinch River Project was to design, build and operate the nation's first large-scale demonstration breeder reactor plant.

The specific objectives were as follows:

"1. To attempt to successfully demonstrate the liquid metal fast breeder reactor in 1983,

2. To help:

I Confirm and demonstrate the potential value and environmental desirability of the LMFBR concept as a practical and economic future option for generating electric power (consideration to the impact of the demonstration plant on the environment will be given throughout the design and planning phase of the project and will be integrated into design and planning decisions.)

II Confirm the value of this concept for conserving important nonrenewable natural resources III Develop for the benefit of government, industry, and the public, important technological and economic data IV Provide a broad base of experience and information for commercial and industrial application of the LMFBR concept V Verify certain key characteristics and capabilities of breeder power plants for operation on utility systems such as licensability and safety, operability, reliability, availability, maintainability, flexibility, and prospect for economy.

PROJECT ORGANIZATION A Partnership of Government and Private Industry T

he Clinch River Project benefited from a unique organization reflecting its partnership arrangement as a joint venture of the federal government and private industry. The U.S. Department of Energy (successor to ERDA) had lead responsibility for managing the project. Day-ta-day management was carried out by a single integrated organization with DOE and the other major project partners consisting of Commonwealth Edison Company, the Tennessee Valley Authority, and Project Management Corporation.

A non-profit organization formed especially for the Clinch River Project, PMC represented the utility industry interests. A second non-profit group known as Breeder Reactor Corporation provided senior counsel on behalf of the utility industry and provided the financial resources from member companies. BRC also was charged with conducting a public information program to keep the public and member companies informed aboutthe project. BRC is composed of 753 electric systems nationwide, and a list of member companies appears in this publication.

Westinghouse Electric Corporation was the lead reactor manufacturer contractor for the project. General Electric Company and the Atomics International Division of Rockwell International were the other two major reactor manufacturer contractors.

Burns and Roe, Incorporated, was the architect-engineer.

Stone & Webster Engineering Corporation was the general construction contractor.

PROJECT MANAGEMENT T

hroughout the duration of the Clinch River Project its management and performance repeatedly won high marks in audits Qnd reviews by government agencies, independent euthorities, .and other panels constituted as a reslJlt .of con@ressional action ClAG! the Initiative of tne executive branc!;) of g0vernmeht. These reviews and audits Included numerous studies conducted by the United States General Accounting Office and the U.S. Department of Energy Office of the Inspector General.

One of the most recent reviews was an audit focusing on management competence by the Inspector General in July of 1982. [20J The auditfound thatthe project was well managed. The management was commended for the "systems and procedures [which] had been implemented throughoutthe project that enabled the project director to exercise effective control and direction over the work done by the various project participants."

Special management systems were developed or adapted for use on Clinch River to control the flow of technical information, control design configurdtion, and monitor cost and schedule performance.

Among these was a computerized interface lata-reporting system. This computerized system was used os a managementtool In cOAtrolllng more than o,500 Interfaces - points of contact between different organizations and decision makers - existing because of the multiple contractors and design teams working on the project nationwide. At one point around 4,000 people located in over 30 states and the District of Columbia were employed on Clinch River contracts. The computerized interface system ensured the integration of the overall project schedule, kept the project on track and resolved problems and differences as they developed.

A Configuration Management Plan established guidelines for the control of the design and any resulting development design changes.

In addition, an "earned value" Performance Measurement System (PMS) was developed for the Clirilch River Project in aC<;:Qrdance with DOE criteria. The PMS provided the basis for the accurate measurement Management Pollees and Procedures of cost and schedule performance. document for the Project The Inspector General report concluded that "despite the many externally caused disruptions to the project. an effective project management structure had been maintained and the project had been advanced significantly at the time of our review."

The U.S. General Accounting Office issued a report to the Congress titled The Clinch River Breeder Reactor-Should the Congress [21)

In this report, the Comptroller General stqted, "The $1.9 billion increase In total estimated project cost has been usec:i by the administration and critics of the LMFBR program as evidence thatthe Clinch River Project, Is not cost beneficial and is no longer justified. However, much of the cost increases are attributed to factors beyond the control of the project management."

TECHNICAL ACHIEVEMENTS Design W

hen the project was terminated, the Clinch River plant design was at the forefront of LMFBR technology and incorporated many advanced technical features not contained in other plants here and overseas.

During the decade it was under development. the plant design was continuously updated to incorporate the latestfeatures and innovations in the United States and abroad. The plant design was over 90 percent complete by 1983 with 8,000 of nearly 10,000 major architect-engineer drawings delivered but with many detailed drawings yet to be produced. In many ways the design represents a major step beyond the technical sophistication of earlier domestic and foreign breeders.

Among the advanced features of the Clinch River design were:

  • A heterogeneous core that improved core performance, In-creased breeding ratio and en-hanced safety.
  • The development of high-temp-erature design criteria which provide a solid base for the design of systems and com-ponents Irrespective of their size and serve as a reference basis for future LMFBR plants.
  • Limited free-bow core restraint which mechanically re-strained the fuel and blanket assemblies Full-scale mockup of the heterogeneous core during normal and off-normal operation.
  • A shorf-shaft pump that was smaller than previous pumps but yielded greater pumping capacity.
  • The adoption of multiplexing for the instrumentation and control circuits connecting the control room to the plant systems. Multiplexing substant-ially reduced cable require-ments and would have saved millions of dollars In the cost of the plant.

and the bent-tube or "hockey stick" steam generator.

Improved Core Design One of the most significant features of the plant design was its heterogeneous core, This core design was adopted for the plant in 1979. The design extends fuel life, ensures safe operation, and breeds new fuel with greater efficiencies than previous designs.

In the heterogeneous core, the blanket elements not only surround the core, but ore also interspersed within the core. The advantages of the heterogeneous core included:

  • Enhanced breeder performance
  • Greater margins of safety
  • Improved fuel performance and fuel reliability
  • Greater flexibility for testing alternate fuel cycle
  • Increased breeding ratio for large plants
  • The adoption of this advanced core design by CRBRP required an exhaustive series of core physics simulation experiments in the Argonne National Laboratory's Zero Power Plutonium Reactor to verify the analytical predictions, The sophisticated analytical tools used to analYze this core design have been verified by extensive in-reactor and out-of-pile tests for physics, thermal hydraulics, struc-ture, restraint system, and thermal Zero Power Plutonium Reactor at striping, Further, reactor safety Argonne National Laboratory 21

advanced the application of new materials and metallurgical procedures to meet the challenges of high-temperature design for the reactor industry.

Advancements were also made in a host of systems and components. Foremost among these were the reactor vessel closure, the control rod systems, the sodium pump, the steam generator and the lower and upper internals of the reactor vessel. The project developed a number of unique high-temperature and seismic design methods.

Closure Head A reactor vessel closure head of innovative design was developed for the project. A unique triple-rotating-head design permitted unhindered, vertical access to all removable core components. This allowed the reactor to be refueled without removing the head. Also, all refueling components could be maintained by hands-on maintenance procedures, thus ensuring high reliability of all refueling operations.

A computer-driven system moved Reactor vessel closure head the head so it could be positioned precisely over the exact location desired by the operator. The positioning accuracy of the refueling machinery to drive the SOO-ton, 20-foot diameter rotating heads was demonstrated by repeated tests. The tests confirmed that the 27

Sodium Pumps A nother example of advanced technology developed for the Clinch River Project is its large sodium pump. The Clinch River design is a vast improvement over previous pumps. The sodium pump for FFTF is capable of pumping 14.500 gallons per minute. The pump for Clinch River could circulate 33,700 gallons per minute even though it was smaller and less expensive to build than its FFTF predecessor.

This pump circulates sodium to remove heat from the reactor core and transfer it to another part of the plant where steam is produced to generate electricity. Six pumps would have been used in the Clinch River plant.

A year-long series of sodium pumping tests were successfully completed in 1983 demonstrating that the pump and its drive motor would meet all operational design requirements. The tests disclosed that the pump was easy to assemble and disassemble and was highly reliable. The pump was tested under severe conditions that simulated the 30-year design life of the plant. These included severe temperature transients ranging from 10000 F down to 700 0 F in a matter of seconds during which the pump continued to operate without fault.

The Clinch River design incorpo-rated features developed through unique high-temperature design capability. Designers reduced the pump shaft length to 13 feet less than the FFTF pump. This resulted in con-siderable cost savings. The pump featured a double-suction impeller that significantly improved performance, Prototype sodium pump internals 28

Electromagnetic Pump T

he Clinch River Project

= developed an Electromag-netic (EM) Pump that was a significant improvement over the performance and efficiency of predecessor models.

An EM pump is a single, rugged device with no moving parts that causes an electrically conducting fluid such as liquid sodium to flow by exerting a magnetic force. Four EM pumps were to be used in the Auxiliary Liquid Metal System used to cool spent fuel from the reactor and to remove decay heat from the reactor itself in some emergency situations.

The design features a unique throat with six rectangular parallel-flow passages. These throat passages were successfully fabricated from a solid piece of steel by means of an electrical discharge machining method that allowed for the components to be fabricated without welding. The technique eliminated distortion and simplified inspection.

Under test in sodium at temperatures up to 11300 F - a maximum emergency temperature for the primary sodium pump - the prototype EM pump met and generally exceeded all performance specifications.

Nominal rating for the EM pump was 400 gallons per minute at a pressure of 60 pounds per square inch. The pump achieved flow rates of 800 gallons per minute at this pressure and could generate pressures up to 200 pounds per square inch at lower flow rates.

EM pumps of earlier design attained efficiencies on the order of 15 percent. The Clinch River electromagnetic pump de-monstrated a peak efficiency in excess of 40 percent.

S ome major problems resulted from this design. This excavation wouid have required the removal of a large amount of rock which would be both costly and time consuming.

Also, crane access to the bottom of the excavation was a major concern because the excavation severely limited the areas where cranes could be located. Lack of surface area for storing construction material and equipment was also a problem, since the excavation took up such a large area of the site.

As a result of these problems. the design was altered. This alteration required near-vertical faces on the north, east and south faces and a face sloped 26 degrees from horizontal on the west side. It also provided areas to locate cranes and to store construction material and equipment and reduced the amount of rock to be removed.

The vertical walls of the excavation were anchored in place with over 2,400 rockbolts. These steel bolts.

ranging in size from 5 to 50 feet long, were imbedded in the rock and cemented and bolted securely to the face of the wall. The technique saved over $5 million and reduced the schedule for site preparation by nearly three months in spite of record-breaking rains which hindered site work.

Preliminary site work was essentially completed by the end of 1983 and included ali sediment ponds, quality control test laboratory, Proposed site redress concept and other construction shops.

Upon termination. of the project planning was initiated for redress of the site to return it to an environ-mentally and aesthetically acceptable condition if no alternative use of the site in its present condition can be found.

In addition, DOE commented that the Memorandum of Findings "confirms the technical merit and safety of the plant as planned and designed and provides firm conclusions regarding the safety and environmental acceptability of breeder reactors." The Department concluded that the decision and the extensive evaluation and review process leading up to it provided "further confidence in the safety of LMFBRs and support for continued development of technology for a virtually inexhaustible energy o
