l Big Rock Point Semiannual Radioactive l
Effluent Release Report January - June 1988 This report provides information relating to the radioactive ef fluent releases and solid radioactive waste disposal operations of Big Rock Point during the
(
period of January - June 1988. Format for this report is contained in Tech-i nical Specification 6.9.2.2.
Big Rock Point was off-line for the second quarter of 1988 due to a refueling outage.

Supplemental Information A.
Batch Releases Information re sting to continuous and batch releases of gaseous and liquid offluent is provided in Table HP 10.3-1.
B.

2.
Caseous Effluents Table HP 10.3-2 lists and sununarless all gaseous radioactive ef fluents l
l released during the reporting period. There was no reported unidentified I
beta for the total release. The maximum noble gas release rate for the l
first and second quarters was 2.93E+02 and 2.15E+02 pci/second, l
respectively.
3.
Liquid Effluents Table HP 10.3-3 lists and suonarizes all liquid radioactive ef fluents released during the reporting period. The unidentified beta was 25.0% of the total release. The maximum liquid effluent release concentration for i
the first and second quarters was 4.94E-07 and 1.4.E-06 pC1/mt,
l respectively.
4.
Solid Radioactive Weste Solid radweste classification sources, volume shipped, curie and nuclide content are detailed in Table HP 10.3-4 Two radwaste shipments were processed and sent to Barnwell, South Carolina for burial.

Sunenary of R dioloalcal Impact on Man 3
Potential doses to individuals and popule:lons were calculated using CASPAR and LADTAP computer program codes. The first and second quarter values for curics released were input for each nuclide and summarized as follows i

A.
The maximum offs?.e air dose due to roble gases was 9.97E-03 millirad beta and 1.73E-02 millirad gamme for the first quarter at site boundaryt and 2.3E-03 millirad beta and 1.96E-03 milliras.

B.
The most rencrictive organ dose to ar individual in an unrestricted area (based on identified celtical receptors) f rom gaseous ef fluents (tritium, poeticulates, and iodines) was the infant thyroid for the first quarter and chlid bone for the second quarter. Doses vere 2.96E-03 m!U lrem and 2.83E-03 millirem, respectively.
C.
The maximum total body dose to individuals sedult) in unrestricted water-related exposure pathways was 4.40E-02 millirem for the first quarter and 4.74E-02 millirem for the second quarter. Tt.e as.irum organ dose was the child bone for the first and secone quartars.
Doses were 7.14E-02 millirem and 1.00E-01 millirem, respectively.

Su pplement a t Inf ormation to the BRP July-December 1987 Semi-Annual Radioactive Effluent Release Report The Big Rock Point Semi-Annual Radioactive Ef fluent Release Report July Deceober 1987, tSe following revisions are being submitted:

E.
In the BRP July - December 1987 Semi-Annual Radioactive Effluent L
Release Report narrative the following changes are also notedt Item 2 - Caseous Effluents:
change f rom "the unidentified beta was 3.10E-06% of the total release" to "the unidentified beta was 3.45E-06% of the total release".
Item 3 - Liquid Effluentet change from "the unidentified beta was 15.6% of the total release" to "the unidentified beta was 15.7% of the total release".
Reasons for the above data revisions to the Big Rock Point Semi-Annual Radioactive Effluent Release Report, July - December 1987 was that the calculated Sr-89 and Sr-90 release quantities (gaseous and liquid effluents, 4th Quarter only) were based on estimated values for the months of October - December. Teledyne Isotopes Midwest Laboratory had out yet completed the actual sample analyses prior to the Technical Specification Semi-Annua! Report due cate. All data changes are indi-cated by "#
in the right-hand margins. There were no significant dose changes to the public.
