additional transmission costs are incurred. For relatively short dis-
tances, that is, less than 100 miles, the investment in transmission lines
will be of the order of $60,000 per mile. For longer lines, higher volt-
ages are necessary and the cost increases to about $150,000 per mile, as
shown in Table 1.5. Corresponding power costs for 100- to 350-mile lines
for 500-Mw(e) plants range from 0.3 to 2.2 mills/kwhr. Actual costs for
construction and operation can vary widely depending upon the voltage to
be transmitted and the type of lines used.

aAt an interest charge of 14.0% and a 0.8 load factor.
It is apparent that some sort of balance can be achieved between the
type and cost of containment and the additional transmission costs incurred
because of remote siting. This is illustrated by Table 1.6, which gives
containment and incremental transmission costs for a 500-Mw(e) direct-cycle
boiling-water reactor. This sort of analysis should, of course, be done
for each type of reactor, since there is no general relation that repre-
sents unit containment costs as a function of method of containment for
all types of reactors.
