Nucted' FEB 271987 NLR-N87033 United States Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 Gentlemen:

RADIOACTIVE EFFLUENT RELEASE REPORT - 2 HOPE CREEK GENERATING STATION DOCKET NO. 50-354 As required by Section 6.9.1.7 of Appendix A to the Operating License for the Hope Creek Generating Station (HCGS), we hereby transmit one copy of the semi-annual radioactive Effluent Release Report, RERR-2. This report summarizes liquid and gaseous releases and solid waste shipment from the HCGS for the period July - December 1986.

Additionally, please find one copy of the revised Offsite Dose Calculation Manual (ODCM). A summary of the changes and their rationale is provided in Attachment A. Changes to the document are delineated by vertical lines in the margin of the text. The majority of changes were completed to support a standardization of the ODCMs for the three nuclear plants at Artificial Island.

Should you have any questions regarding this material, please feel free to contact us.

Sincerely, Attachments G703030b09 070DD7 em Aeocx eeeeems y:s e vou

ATTACHNENT A HOPE CREEK DOSE CALCULATION MANUAL

SUMMARY

OF CHANGES The changes to the Hope Creek Offsite Dose Calculation Manual consisted of the following:

1) Updating the Site Related Dose Ingestion Factors to include Cobalt-57, Bromine-82, Niobium-97, Rhodium-103m, Rhodium-106, Antimony-124 and Antimony-125.

RATIONALE: For completeness (Dose code contains values but ODCM Table previously did not).

2) Updating and listing all the Pathway Dose Factors to include Cobalt-57, Antimony-124 and Antimony-125.

RATIONALE: For completeness (Dose code contains values but ODCM Table previously did not). These changes were made to provide consistency between Salem and Hope Creek ODCMs.

3) Providing default equations to ensure compliance with Technical Specifications for

a. Liquid and Gaseous Monitor Setpoints

b. Liquid and Gaseous Dose Limits RATIONALE: To provide hand calculation capability in case of computer hardware / software problems. Method provides conservative results with respect to release specific analysis (See Appendices in ODCM). These changes were made to provide consistency betweeen Salem and Hope Creek ODCMs.

4) Providing Technical Basis fort I a. Default MPC Value for Liquid Effluents i b. Effective Dose Factors - Liquid Effluents

c. Effective Dose Factors - Gaseous Effluents

d. Effective Dose Parameters - Gaseous Effluents RATIONALE

Technical Basis previously unavailable within text. These changes were made to provide consistency between Salem and Hope Creek ODCMs.

5) Describing calculation of doses due to activities inside the l Site Boundary.

i RATIONALE: Previously unavailable within text. These l changes were made to provide consistency between Salem and Hope Creek ODCMs.

6) Describing Gaseous and Liquid Effluent Dose Projection Calculation.

RATIONALE: Previously unavailable within text. These changes were made to provide consistency between Salem and Hope Creek ODCMs.

7) Changing bioaccumulation factors to saltwater fish and saltwater invertebrates (eliminate fresh water analyses).

RATIONALE: Change to saltwater because plant is on estuary and pathway is therefore saltwater. These changes were made to provide consistency between Salem and Hope Creek ODCMs.

8) Updating the Radiological Environmental Monitoring Program sample locations (as per census).

The revision number on the manual reflects several changes approved by the Station Operating Review Committee (SORC) during the period July through December 1986. These modifications were used in the generation of RERR-2 for the second half of 1986.

A list is provided in Attachment B which highlights those items in the Salem and Hope Creek ODCMs which could not be standardized due to design, plant hardware, or Technical Specification differences between plants.

ATTACHNENT B NAJOR DIFFERENCES BETWEEN HOPE CREEK AND SALEM ODCN The following highlights the differences between Hope Creek's and Salem's Of fsite Dose Calculation Manuals.

Salem Hope Creek

1) Salem uses circulating Hope Creek uses the Cooling water system for dilution Tower Blowdown Discharge in liquid releases. This system for dilution in dilution rate (1.85E+05 liquid releases. This gpm) is used in setpoint dilution rate (2.5E+4 gpm) calculations and dose is less than Salem's and assessments. As the is also used in setpoint dilution rate is more calculations and dose than Hope Creek's the assessments.

dose rate calculations would thus reflect the difference.

2) Salem utilizes four liquid Hope Creek uses two liquid effluent monitors for four effluent monitors. One at different areas; the the discharge line the other discharge line, steam at the cooling tower blowdown generator blowdown line, dischargo line.
