RE: N-16 equilibrium in coolant ???

["Morgan, Ben" <ben.morgan@cplc.com>]

James,

Regarding your question about N-16 in power reactor coolant. There is a
table (Table 11.1.4-1) in our Safety Analysis Report which gives values
of N-16 at various points in the coolant loop. Unfortunately this
information comes from a proprietary Westinghouse document and so I
can't list it here. Other reactors would have a similar table and if you
have access to one of these safety reports you can look it up.

Also, pages 520 - 524 of the 2nd edition of Lamarsh's "Introduction to
Nuclear Engineering" gives the formula for determining this number and,
for a reactor with a power density of 55 watts/cm^3 in which the coolant
is in the reactor for three seconds and outside the reactor for two
seconds, the N-16 equilibrium activity is 249 uCi/cm^3.

Sorry I can't be more specific.

Ben
