natural uranium to about 2 to 4 wt.%, the initial enrichment for LWR fuel) of a
pure uranium hexafluoride product stream, while depleting the bulk of the natural
uranium to a "tails" enrichmentdf*0.3-wt.%, at present. These plants are very
large in size, investment, and electrical power consumption. The AEC plants are
characterized by very large continuous-floor-area buildings on reasonably flat land
and require access to abundant and inexpensive electric power and process cooling
water. The total AEC complex presently has an estimated capacity of 10.5 x 106 kg
of separative work units per year while requiring the output from about 3250 MWe of
electrical power; the annual requirements of the model 1000-MWe-LWR fuel cycle are
about 116,000 kg of separative work units. It is anticipated that an extensive
program12 of process improvement and up-rating of the AEC plants will raise the
total capacity by 1980 to 27.7 x 106 kg of separative work units per year and the
required electric power consumption to 7380 MWe/year.
6A.l.l.3.4 Energy Transmission
All nuclear, fossil-fueled, and hydroelectric power stations will require trans-
mission lines for the distribution of the electrical energy they produce.16,17
Transmission line locations and designs are major aesthetic concerns. Fortunately,
the design17 of transmission lines has improved considerably in recent years so
that it is now possible to deal effectively with most objections of an aesthetic
nature. The environmental impact of transmission lines will be minimized through
advanced planning and careful design and through review and approval of proposed
transmission facilities by appropriate Federal, state, regional, and local
authorities.
6A.l.l.4 Research and Development Program
Components and systems technology for producing nuclear power in LWRs has advanced
to the status of commercial applicability, and any further research deemed neces-
sary to optimize systems and economics lies within the purview of those industries
which will benefit therefrom. While the accumulated information in nuclear technol-
ogy, as in any other body of knowledge, is not without gaps and uncertainties in the
accuracy of data, there are many options available in design, engineering, and
operation of nuclear plants to compensate for uncertainties and to reduce associ-
ated risks to acceptable, low values. Redundancy in components and instruments,
conservative engineering practices to provide substantial margins, redundant safety
devices and systems, fission product barriers, and a wide range of choices in
operating parameters are being used to produce safe and reliable plant designs.
Similar flexibility in engineering and operational practices is available to resolve6A.1-49
