INTRODUCTION
The Yankee Atomic Electric Company has contracted with the Westinghouse Atomic
Power Department under Yankee Contract No. 1 of Contract AT(30-3)-222 between
the U. S. Atomic Energy Comission and the Yankee Atomic Electric Company to
perform the research and development work required to build a 134 MW (net
electrical output) pressurized light water nuclear reactor power plant using
slightly enriched uranium dioxide (rio2) fuel pellets contained in stainless
steel tubes.
YAEC Development Program Report, YAEC-61, Revision 1, outlines the Research and
Development Program for the period from July 1 to December 31, 1958. Quarterly
Progress Reports, YAEC-7, YAEC-13 (Revision 1), YAEC-20, YAEC-35, YAEC-4h,
YAEC-52, YAEC-65 and YAEC-87 describe and evaluate the work accomplished from
the beginning of the program, June 6, 1956 to June 30, 1958.
The basic objectives of the YAEC Research and Development Program are:
1. The carry out the development of stainless steel U02 fuel rods to a point
where successful operation of experimental elements in a test reactor
has been demonstrated.
2. To improve the process of manufacturing sintered U02 fuel pellets for
the rod elements and, to reduce fuel preparation costs.
3. To select a proven material or to demonstrate the feasibility of a
material suitable for use in control rods for a long-lifetime pressurized
water reactor core.
h. To obtain through analysis and experiments a thorough understanding of
the nuclear physics aspects of the proposed stainless steel U02
pressurized water reactor.
5. To obtain an optimized preliminary design for a nuclear reactor and
associated auxiliaries for a turbine electric power plant based upon
the use of a stainless steel clad long-life core.
6. To determine the proper primary system materials, the required efficiency
of the wnter purficiation system, the selection and use of a soluble
neutron absorber and the minimizing of crud deposition through water
chemistry analyses.
"Information Availability Report", YAEC-30 for the period from June 6, 1956
to September 30, 1957, and Quarterly Progress Reports, YAEC-4h, YAEC-52,
YAEC-65 and YAEC-87 for the third and fourth quarters of 1957 and the first and
second quarters of 1958, covered the availability of information to, and the
difficulties encountered by the Westinghouse Atomic Power Department and the
Yankee Atomic Electric Company in their efforts to obtain documents and reports
to further the success of the YAEC Research and Development Program. The five
reports also included a section containing abstracts of trip reports made
under the YAEC Research and Development Program.
A cut-away drawing of the positive engagement type control rod drive mechanism
being procured under subproject 4.2 is shown on the following page.- 9 -
