1. 0 RADI0 ACTIVE LIQUID RELEASES i

i The total radioactive liquid release excluding tritium for this reporting period was 5.46E-01 curies. This included 5.01E-02 curies in processed radioactive waste and primary coolant system letdown,1.54E-01 curies in Unit 1 steam generator blowdown, 3.34E-01 curies in Unit 2 steam generator blowdown, 6.22E-04 curies in the retention pond, ana 7.40E-03 curies in miscellaneous Unit 1 discharges.  !

The total tritium release for this reporting period was 3.04E+02 curies.

This included 3.00E+02 curies in processed radioactive waste and primary coolant system letdown, 2.10E-02 curies in Unit 1 steam generator blowdown, 1 2.85E+00 curies in Unit 2 steam generator blowdown, 6.49E-01 curies in the {

retention pond, and 2.76E-01 curies in miscellaneous Unit 1 discharges.

All radioactive liquid releases to Lake Michigan were made through the l circulating water discharge system.

1.1 Circulating Water Radionuclides Release Summary j 1.1.1 Releases During Current Reporting Period Radioactive liquid releases via the circulating water discharge ,

are summarized by individual source, total, and equivalent curie l release on a monthly basis and presented in Table 1-1, 1.1.2 Additions to Previous Semiannual Monitoring Report 1 i

The following information was not available at the time of previous report preparation and should be added to Table 1-1 of the Semiannual Monitoring Report for July 1, 1986 through December 31, 1986.

• Scheduled chemical waste releases to the circulating water system from January 1, 1987 to June 30, 1987 included 4.17E+06 gallons of neutralized wastewater. The wastewater contained 5.10E+02 pounds of suspended solids and 5.06E+05 pounds of dissolved solids.

• Scheduled chemical waste releases are based on the average analytical results obtained from sampling a representative number of neutralizing tanks.

• Miscellaneous chemical waste releases from the retention pond (based on effluent analyses) to the circulating water for January 1, 1987 to June 30, 1987, included 1.43E+07 gallons of clear wastewater.

The wastewater contained 1.19E+03 pounds of' suspended solids.

Miscellaneous chemical waste released directly to the circulating water, based on amount of chemicals received, for January 1, 1987 to June 30, 1987 included 7.95E+04 pounds of sodium bisulfite and 2.99E+04 pounds of sodium hypochlorite.

7.0 CIRCULATING WATER SYSTEM OPERATION The circulating water system operation during this reporting period for periods of plant operation is described in Table 7-1.

8.0 LEAK TESTING OF RADI0 ACTIVE SOURCES During this reporting period all applicable sealed radioactive sources were leak tested in accordance with Technical Specification 15.4.12.

Leak test results were all <0.005 uCi.

9.0 MISCELLANEOUS REPORTING REQUIREMENTS 9.1 Revisions to the PBNP Offsite Dose Calculation Manual (ODCM) and Process Control Program (PCP)

No revisions were made to either the ODCM or PCP during this reporting period. However, changes were made to the Environmental Manual which is incorporated to the ODCM by reference. The new revisions cannot effectively be ider.tified in the Semiannual Report. Therefore, a complete copy of the Environmental Manual will be forwarded to the Nuclear Regulatory Commission.

9.2 Interlaboratory Comparison Program The analytical laboratory contracted to perform the radioanalyses of PBNp environmental samples participated in the EPA Interlabora-tory Comparison Program during this reporting period.

9.3 Deviations from Specified Environmental Sample Types, Locations, and Frequencies One deviation from sampling types, frequencies, and locations specified in Technical Specification 15.7.7 occurred during this reporting period. A particulate air filter was lost in the field.

9.4 Summary of Unachievable Specified Environmental LLDs LLDs listed in Table 15.7.7-2 of the PBNP Technical Specifications were accomplished for all samples during this reporting period.

9.5 Special Circumstances No special circumstances report regarding operation of the explosive gas monitor for the waste gas holdup system were needed during this reporting period.

l PBNP ENVIRONMENTAL MANUAL REVISION 5 - APRIL 1987 The Point Beach Nuclear Plant Environmental Manual has been revised. The changes are indicated by vertical lines in the right hand margin of the revised pages. The changes are identified and a short explanation of the changes are given on the attached page.

These changes improve the overall effectiveness of the radiological environ-mental monitoring program by clarifying procedures and responsibilities and by updating forms used for recording data.

l i

Change Descriptions for the PBNP Environmental Ma'nual Revision 5 -- April 1987 i 1.2.2.1 A new section which states that PBNP has the responsibility for

' distribution of the Environmental-Manual.

2.2.6 References'a CHP form (Figure 2-6) for completeness,

2. '3 Removed the reference to the State of' Wisconsin: sampling data sheet 'it is not necessary to be included in the document.

Reworded precipitation collection to twice per month instead of every other week. Also gave new address of where samples are sent.

2.4.3, 2.4.4 Changed recommended minimum volume from 4E to 82 per and Table 2 Teledyne Isotope's request, as a volume larger-than 42 is.

required to complete certain analyses.

2.4.5.1c Consolidated steps.c and d from the original document.

'2.4.5.le Inserted a new step as a reminder to write data on the sample envelope prior to inserting the AP so as not to potentially i transfer radioactive material from the AP to the envelope if the AP is in the envelope when it is written upon. '

2.4.5.2 Inserted " rigid plastic tubing" as allowed, because the intent of previous wording was to forbid the use of soft, collapsible tubing but not to forbid the use of plastic tubing.

2.4.5.3 Redefines air sampler calibration consistent with the methodology contained in Health Physics procedure HPIP 9.51.

2.4.5.4 A maximum interval between leak checks is-stated, which wa's  !

not included in the original version. A slightly reworded leak j

check interpretation is now consistent with HPIP 9.51.

2.4.6 "Last" was changed to "first" to reflect the current milk j sampling routine which is now completed at the beginning of a the month. This practice allows extra time if samples are '

initially unavailable .to meet the Technical Specification time requirement for monthly sampling.

2.4.10 Provided an example of proper shoreline sediment collection for clarity.

Table 2-3 Changed the location description of E-08 due to relocation of and Figure 2-1 this sampling station in late 1986.

Figures 2-2, CHP forms which have either been newly inserted into the manual 2-4,-2-6, 2-7 for clarity or have undergone revision since the last Environmental Manual change.
