Cook Plant preoperational studies, 1969 / John C. Ayers ... [et al.].

depth is fairly equitable to distance from shore. Except for two most landward rows of sampling stations (at 15 and 30 feet of depth), comparability of
depth is taken to be achieved by equal distances from the beach.
From a consideration of all the above points, the system of sampling
illustrated in Figure 27 evolved.
Because the Cook plant area is devoid of charted landmarks sufficient to
enable the use of sextant fixes, it will be necessary to navigate by radar
ranges and bearings. Although the sampling station system is designed to
produce an arc with a radius of seven-miles around the outfall of the Cook plant,
it is practical to occupy the sampling stations only on courses perpendicular
to shore where radar distances to shore and to the St. Joseph pierheads can be
used as the primary fix. The radar azimuths to both locations,however, may be
used as back-up fixes. We believe that the sampling system proposed meets as
well as possible the fundamental design-of-experiments concepts that must be met;
we know it meets as well as possible the practical navigational problems; and we
think it meets the requirement of concentrating data in critical areas. We will
not hesitate to modify it if we acquire evidence that something else is better,
but we consider this to be presently the best possible arrangement of sampling
stations around the Cook plant. Unless serious objection comes to light before
the 1970 ship-operating season, this system of sampling stations will be put
into effect in spring (probably May) of 1970 and continue in effect in spring (May),
summer (August), and fall (October-November) throughout the preoperational and
postoperational surveys needed by the Cook Nuclear Plant.
