Attention to Liquid Dilution Volumes in Semiannual Radioactive Effluent Release Reports
HPPOS-099 PDR-9111210218
Title: Attention to Liquid Dilution Volumes in Semiannual
Radioactive Effluent Release Reports
See the memorandum from C. A. Willis to W. W. Meinke and C.
L. Miller dated November 7, 1984. The memo states that for
semiannual effluent reports pursuant to Regulatory Guide
1.21, licensees should use the total volume of dilution
flow, not just the flow during the time of liquified
effluent release. [Note: Effluent reports are now
required annually.] The dilutional volume (or flow) must
be determined specifically for each plant. In addition, a
table of expected dilution volumes may be prepared by the
contractor using data from various environmental
statements, ODCMs, etc.
