BIG ROCK POINT RADIOACTIVE EFFLUENT RELEASE REPORT Januarv 1.1997 to December 31.199Z This report provides information relating to radioactive effluent releases and solid radioactive waste disposal at Big Rock Point for all of 1997. The report format is detailed in Plant Technical Specification 6.9.2.2.

Big Rock Poir.t began 1997 in a shutdown for turbine repairs. The Plant returned to operation February 1,1997 and ran until March 2,1997 when the Plant was shutdown to repair core spray valve leakage and rerate the Post incident System design pressure. The Plant returned to power operation on May 5,1997 and ran continuously until August 29,1997 when the Plant was permanently shutdown for decommissioning.

1. Sucolemental Information A. Batch Releases Informat on relating to continuous and batch releases of gaseous and liquid eff.pnts is provided in Table HP 10.3-1, Attachment 1.

B. Abnormal Releases i

None l C. Lower Limits of Detection (LLDs) for gaseous and liquid effluents is provided in Attachment 5.

D. Radioactive Effluent Monitoring instrumentation Big Rock Point Technical Specification 13.1.1.1.b requires that with less than the minimum number of radioactive effluent monitoring i instrument channels operable, the action shown in Table 13-1 shall be I taken. Exert best efforts to return the instruments to operable status '

within 30 days and, if unsuccessful, explain in the next Radioactive Effluent Report why the inoperability was not corrected in a timely ,

manner. ,

No radioactive effluent monitoring instrument channels were inoperable for more than 30 days during this reporting period.

2. Gaseous Effluents Table HP 10.3-2 (Attachment 2) lists and summarizes all gaseous radioactive effluents released during the reporting period. The unidentified beta was 2.99E-05% of the total release. The maximum noble gas release rate for 1997 occurred during the second quarter at 2.62 E+02 uCi/second.

Gaseous Effluents resultant Airdose in 1997 was somewhat lower than those of 1996. This decrease is a direct reflection in the difference in Power Operation of the Plant between the two years, with Big Rock being shut down for l decommissioning on August 29,1997. l

3. Ligid Effluents l l

Table HP 10.3-3 (Attachment 3) lists and summarizes all liquid radioactive effluents released during the reporting period. There was no unidentified beta reported in 1997. The maximum liquid effluent release concentration for 1997 occurred during the fourth quarter at 5.39E-07 uCi/ml.

1 Liquid Effluent curies released and resultant wholebody and organ dose commitments in 1997 were less (by factor of ten) than that of 1996.1997 liquid effluent releases were more in line with previous years (1994, and 1995),

with 1996 releases being an outlier due to elevated Total Organic Carbon (TOCs) levels that did not allow for the process and reuse of water per normal operations.

! 4. Solid Waste Table HP 10.3-4 (Attachment 4) summarizes all soliu tadwaste volume shipped, classification, processing employed, sources, curie and nuclide content. All radwaste shipments were made to the Barnwell Waste Management Facility in Barnwell, South Carolina.

5. Summarv of Radiologicalimoact on Man Potential doses to individuals and populations were calculated using GASPAR and LADTAP computer program codes. The quarterly values for curies released were input for each nuclide and summarized as follows:

A. The maximum total body dose to an individual in unrestricted water-related exposure pathways was First Quarter 1.21 E-02 millirem (adult)

Second Quarter - 3.19 E-03 millirem (adult)

Third Quarter - 2.15 E-03 millirem (adult)

Fourth Quarter - 2.45 E-02 millirem (adult)

The maximum organ doses were:

First Quarter - 2.14 E-02 millirem (teenage liver)

Second Quarter - 5.33 E-03 millirem (teenage liver)

Third Quarter - 3.85 E-03 millirem (teenage liver)

Fourth Quarter - 4.26 E-02 millirem (teenage liver)

B. The offsite air dose at the site boundary (0.57 mi E) due to noble gat as were:

First Quarter - 1.61 E-03 millirad beta and 2.77 E-03 millirad gamma Second Quarter - 4.43 E-03 millirad beta and 7.68 E-03 millirad gamma Third Quarter - 4.40 E-03 millirad beta and 7.67 E-03 millirad gamma Fourth Quarter - 0.00 E+00 millirad beta and 0.00 E+00 millirad gamma The maximum noble gas offsite air dose to the nearest residence (critical receptor at 1.4 mi E) occurred during the second quarter, at 3.57 E-03 millirad beta and 5.97 E-03 millirad gamma.

C. The most restrictive organ dose to an individual in an unrestricted area (based on identified critical receptors) from gaseous effluent releases (tritium, particulate and iodine) was the child bone for all four quarters. Doses were:

First Quarter - 2.27 E-03 Second Quarter - 6.69 E-03 Third Quarter - 9.75 E-03 Fourth Quarter - 5.69 E-05 D. Integrated total body doses to the general population and average doses to individuals within the population from liquid effluent release pathways to a distance of 50 miles from the site boundary were First Quarter - 7.67 E-03 person-Rem and 4.21 E-05 millirem.

Second Quarter - 1.48 E-03 person-Rem and 8.13 E-06 millirem.

Third Quarter - 1.43 E-03 person-Rem and 7.86 E-06 millirem.

Fourth Quarter- 1.43 E-02 person-Rem and 7.86 E-05 millirem.

E. Integrated total body dose to the general population and average doses to individuals within the population from gaseous effluent release pathways to a distance of 50 miles from the site boundary were:

First Quarter - 3.00 E-03 person-Rem and 1.65 E-05 millirem Second Quarter - 7.80 E-03 person-Rem and 4.29 E-05 millirem Third Quarter - 7.70 E-03 person-Rem and 4.23 E-05 millirem Fourth Quarter - 2.02 E-05 person-Rem and 1.11 E-07 millirem i

6. Process Control Program (PCP)
No changes were made to the Process Control Program in 1997.
7. Offsite Dose Calculation Manual (ODCM)

There were several changes made to the Big Rock Point Offsite Dose Calculation Manual, Revision 13 as a result of the 1997 Land Use Survey.

1) Update of Table 1.4,1996 Big Rock Point Land Use Censur
2) Update of Table 1.4a,1997 Big Rock Point Land Use Census -

Critical Receotor Items:

3) Update of Table 1.9,1997 Big Rock Point Gaseous Design Objective Annual Quantities The revised ODCM (Attachment 6)is enclosed with this report along with the supporting documentation per the requirements of Technical Specification 6.9.2.2A (5) and 6.15.
