I. INTRODUCTION This Semiannual Radioactive Effluent Release Report for the period of January 1 through June 30, 1988, is submitted in accordance with Section 6.9.1.8 of Appendix A to Grand Gulf Nuclear Station (GGNS) License No. NPF-29.

That portion of Appendix A which refers to the monitoring of radioactive effluents, Sections 3/4-11 and 3/4-12, will hereafter be referred to as the Radiological Effluent Technical Specification (RETS).

Airborne discharges at GGNS are ground-level releases.

All liquid and airborne discharges to the environment were analyzed in accordance with the RETS requirements.

All effluent releases were within the concentration and total release limits specified by the RETS.

Projected offsite doses were within the dose limits specified by the RETS.

The doses were projected using the methodology of the GGNS Offsite Dose Calculation Manual (00CM).

Dose calculations will be summarized in the July-December 1988 Semiannual Radioactive Effluent Release Report.

The summation of all gaseous releases during the reporting period is given in Table 1A, while elevated releases and ground-level releases for the reporting period are given in Tables 18 and IC, respectively.

Table ID describes the radioactive gaseous sampling and analysis program implemented at GGNS.

The summation of all liquid releases during the reporting period is given in Table 2A, while continuous and batch mode releases are given in Table 28.

Table 2C describes the radioactive liquid waste sampling and analysis program implemented at GGNS.

Solid radioactive waste and irradiated fuel shipments during the reporting period are summarized in Table 3.

Meteorological data is included in Tables 4A - 4C.

Measurements and Approximations of Total Activity The following discussion details the methods used to measure and approximate total activity for the following:

1.

Fission and Activation Gases 2.

Radioiodines 3.

Particulates 4.

Liquid Effluents Tables ID and 2C give sampling frequencies and minimuhi detectable sensitivity requirements for the analysis of gaseous and liquid effiuent streams, respectively.

Values in the attached tables given as zero do not necessarily.

imply that the radionuclides were not present. A zero indicates that the radionuclide was not present at levels greater than the sensitivity requirements shown in Tables ID and 2C.

For some radionuclides, lower detection limits than required inay be readily achievable; when a radionuclide is measured below its stated limits, it is reported.

1.

For Fission and Activation Gases The following noble gases are considered in evaluating gaseous airborne discharges:

Ar-41 Xe-131m Kr-85m Xe-133 Kr-85 Xe-133m Kr-87 Xe-135m Kr-88 Xe-135 Kr-89 Xe-138.

Periodic grab samples from Station effluent streams are analyzed by a computerized pulse height analyzer system utilizing high-resolution germanium detectors.

(See Table 1D for sampling and analytical requirements.)

Isotopic values thus obtained are used for dose release rate calculations as given in Section II.A.1. of this report.

Only those radionuclides that are detected are used in this computation.

During the period between grab samples, the amount of radioactivity released is based on the effluent monitor readings.

Monitors are assigned a calibration factor based upon the last isotopic analysis, using the following relationship:

C

= Uj+m j

where isotopic calibration factor for isotope i C

=

j J20SRERR-06/88 - 5

concentration of isotope i in the grab sample, in U

=

g uCi/ml.

net monitor reading associated with the effluent m

=

stream.

(Determined at the time of grab sampling).

These calibration factors, along with the hourly effluent monitor values and. flow rates, are entered into the laboratory computer where the release rates for individual radionuclides are calculated and stored. If no activity is detected in the grab sample, the calibration factor for Kr-85 and the dose factor for Kr-89 are entered into the laboratory computer.

2.

For Particulates and Radioiodines The radioiodines and radioactive materials in particulate form to be considered are:

Zn-65 I-133 Cr-51 Cs-134

-Mn-54 Cs-136 Fe-59 Cs-137 Co-58 Ba-140 Co-60 Ce-141 Sr-89 Other Radionuclides-Sr-90 with half-lives Zr-95 greater than Sb-124 8 days.

l I-131 3.

For Continuous Releases Continuous sampling is performed on the continuous release points (i.e., Radwaste Vent, Containment Purge, Fuel Handling Area Vent, Turbine Building Vent).

Particulate material is collected by filtration.

Radiciodines are collected by adsorption onto a charcoal filter.

Periodically these filters are removed and analyzed on the pulse heigM analyzer to identify and quantify radioactive materials collected on the filters.

Particulate filters are then analyzed for gross alpha and Strontium-89 and

-90, as required.

Gross alpha determinations are made using a 2 pi gas flow proportional counter.

Strontium-89 and -90 values are obtained by chemical separation and subsequent analysis using 2 pi gas flow proportional counters.

During major operational occurrences, the frequency of sampling is increased to satisfy the requirements of footnote "c" of Table 10. "Radioactive Gaseous Waste, Sampling and Analysis," (GGNS RETS, Table 4.11.2.1.2-1).

4.

For Batch Releases: Gases The processing of batch type releases (from Containment Purge) is l

analogous to that for continuous releases.

l J20SRERR-06/88 - 6 L

5.

For Batch Releases: Liquid Effluents The radionuclides listed below are cor.sidered when evaluating liquid effluents:

H-3 Mo-90

.Co-58 Tc-99m Co-60 I-131 Fe-55 I-132 Fe-59 I-133 Zn-65 I-135 Mn-54 Cs-134 Cr-51 Cs-137 S r-89 Cs-140 3r-90 Ba-140 Nb-95 La-140 Zr-95 Ce-141 Ce-144 Representative pre-release grab samples are obtained and analyzed as required by Table 2C.

Isotopic analyses are performed using the computerized pulse height analysis system previously described. Aliquots of each pre-released sample, proportional to the waste volume released, are composited in accordance with the requirements of Table 2C.

Strontium determinations are made by performing a chemical separation and counting the separated strantiue'using a 2 pi gas flow proportional counter.

Gross alpha determinations are made using 2 pi gas flow proportional counters.

Tritium and Iron-55 concentrations are determined by using liquid scintillation techniques.

Dissolved gases are determined employing grab sampling techniques and then counting on the pulse height analyzer system.

Abnormal Releases 1.

Liquid 1st & 2nd Duarter 1988 One abnormal liquid release occurred during the reporting period.

This event was previnusly documented in Incident Report 88-2-5, and NRC Inspection Reports 50-416/88-01 and 50-416/88-03.

Event Summary On January 28, 1988, GGNS personnel discovered that a blocked vent line on the Standby Service Water (SSW) basin overflow line had allowed water to siphon from SSW Basin B to the storm drain system.

The release was terminated on January 29, 1988 when the vent line was repaired.

The total water released was estimated to be 80,000 gallons.

Crab samoles taken from the storm drains and SSW Basin B showed no detectable radioactivity above background.

Though samples were not taken during the actual release period, the SSW radiation monitor was operable and indicated no measurable radioactivity above background.

The cause of the release was an inaccurate Piping and Instrumentation Diagram (P&ID) that did not show the vent line.

The overflow lines on SSW A and B were capped on March 16 and 17 to prevent similar events from occurring.

2.

Gaseous 1st & 2nd Quarter 1988 One abnormal gaseous release occurred during the reporting period.

This event was previously documented in Licensee Event Report (LER) 88-009-00 and NRC Inspection Report 50-416/88-05.

Event Summary On February 27, 1988, hydrogen ignition occurred in the Offgas System causing ignition of the lower charcoal adsorber beds in A and B trains.

The A and B charcoal adsorber trains were isolated with a nitrogen purge to extinguish the charcoal fire.

Gaseous effluents were released without treatment by charcoal adsorption until March 2, 1988 when 3 of 4 charcoal beds in Train A were returned to operation.

J20SRERR-06/88 - 8

The maximum release rate during the event corresponded to a 2.1 mrem / year instantaneous whole body dose rate at the site boundary.

This was well within the regulatory limit of 500 mrem / year.

The event was caused by a malfunction of the A hydrogen recombiner due to wetting of the catalyst during the SJAE A startup sequence.

The system operating instruction for SJAE startup has been revised and design changes are being' considered to improve SJAE startup and operating performance.

Sampling errors include uncertainty associated with mixing, representative sampling and discharge volume.

Measurement errors include uncertainty associated with instrument calibration and the preparatinn and counting of low-activity samples.

Counting errors are based on measurements of blank samples and, for germanium detectors, the least-readily-detectable radioisotope.

Calibration errors are calculated by summing the errors associated with the calibration of a particular instrument with a radioactive source.

Total error is calculated by taking the square root of the sum of the squares of the individual errors.

00CM Revision 12 Revision 12 to the ODCM was reviewed and approved by the Plant Safety lieview Committee on August 9, 1988.

The changes within this revision can be characterized as administrative.

Based on a technical review and consideration of th? reasons for the changes, it was determined that the changes will not reduce the accuracy nor the reliability of the dose calculation or setroint determinations.

Revisicn 12 to the CGNS ODCM was necessary to:

Correct administrative and typograpriaal errors Revise gaseous setooint calculation methodology l

Page 2.0-1

Affected__ Lines:

7, 8, 9, 10, 11, 13 thru 18, 23, 28, 29 Revision / Justification:

Lines 7 & 8:

Inserted "(cpm) above background" for clarification.

Also inserted "tha" preceding "alarm" for grammatical clarification.

Lines 9 & 11:

Replaced "0.25" with the acronym "PF".

The correction factor, PF, is the product of the sa.'ety and allocation factors.

Line 10:

Deleted "(1)" because it was unnecessary.

Lines 13, 14, 15 & 16:

Inserted definitions for the product and allocation factors.

The revised methodology uses a correction factor to adjust for simultaneous release points, fluctuations in instrument efficiencies and other uncertainties.

Line 17:

Replaced "0.25" with "SF" to make defining PF more o'uvious.

Line ;8:

Added ", normally set at 0.4" to provide the routine value of SF.

Using the nor ~1 values of AF (0.25) and SF (0.4), PF equalt I which is more conservative than the previou. value l

(0.25) used as a correction factor in i

determining the monitor setpoint. This accounts for uncertainties including the + 25%

calculated value provision added ir Note 1, Line 6.

I i

Lines 23 & 28: Removed the "less than or equal to" i

symbols because they were unnecessary, I

l Line 29:

Inserted "(cpm) above background" on Line 2 and "cps" on Line 14 to clarify the enit of measurement for count, rate.

Page 2.0-4 Affected Lines:

2, 5 thru 15, 17 thru 22, 25 thru 29 Revision / Justification:

Lines 2, 5, 6, 7, 8:

Replaced "be regarded as upper" with "determine the allowable" on Line 2.

Deleted "lower" on Line 5.

Replaced "than" wit' "that is less than or equal to

+ 25% of" on Lines 5 & 6.

The upper limit was replaced with a + 25% limit to improve flexibility, and takes into account minor changes in isotopic abundances.

On Lines 6, 7 & 8, added a provision for using the existing setpoint if radionuclides are not detected in grab sample.

Lines 9 thru 12:

The explanatory statement for Note 2) was expanded to clarify that the conservative setpoint methodology could be used to minimite the need for setpoint adjustment as well as when radioactivity was not detectable.

Liner 13 thru 15:

Provided the definition of S and y

the equation for determining monitor setpoint.

As indicated by the footnote to the S definition, the setpointwillbe8asedonlyontotal body dose because it is always a more conservative value.

Therefore, reference to skin dosr s deleted.

Lines 17 & 18: Inserted a definition for PF.

Lines 19 & 20: Repeated the definition for AF to avoid confusion.

J20SRERR-06/88 - 22

Lines 21 & 22: Inserted a definition for SF' to account for uncertainties including the i 25%

d9tector efficiency range added by Lines 14 & 15 of Page 2.0-5.

Lines 25 & 26: Simplified the equation for R " by combiningtheexistingequatibnforR" t

and the equation for C'.

This combination took into consideration the change to reciprocal units for X as noted on page 2.0-5.

As a result the definitions for Q" and C' were no longer necessary and were deleted.

Lines 27, 28, 29:

Added a footnote to explain why it was not necessary to calculate a setpoint based on skin dose.

Page 2.0-5 Affected Lines:

2, 3, 4, 7, 8, 12 thru 15 Revision / Justification:

Lines 2, 3, 4: Restated the definition for X to identify the source of the efficiency factor and to show use of reciprecal units.

Lines 7 & 8:

Cle.rified definitions for conversion factors.

Line 12:

Added the value of K from Table 2.1-1 because it it constant for Kr-89.

The definitions for R ", L and M were deleted since they will no 18ngerbeused.

Line 13:

Added a statement identifying the location for definitions of variables not provided on pages 2.0-4 & 5.

Lines 14 & 15: Added a requirement for instrument calibration to ensure effic.iencies remain within the i 25%.ange.

2)

A more conservative setpoint may be calculated usin0 the conservative Kr-89 total body dose factor.

This method may be used when there are no valid isotopics available.

The conservative setpoint will be calculated as follows:

Where:

product of allocation factor (AF) and safety factor PF'

The setpoint calculation based on a Kr-89 skin dose is not required because the setpoint based on a Kr-89 total body dose will always be more conservative.

(mrad /yr per pCi/m ) from Table 2.1-1 The highest annual average X/Q for the GGNS SITE BOUNDARY or UNRESTRICTED AREAS inside the SITE BOUNDARY is Hamilton Lake (WNW, 0.75 miles).

This value is taken from the Grand Gulf Nuclear Station Final Environmental Report, Table 6.1.28.

NOTES For Section 2.1.1 1)

The calculated setpoint values will determine the allowable l12 bounds for the actual setpoint adjustments.

That is, setpoint adjustments are not required to be performed if the existing setpoint level corresponds to a count rate that is less than or equal to + 25% of the calculated value.

If radionuclides are not detected in the grab sample, then the previously calculated setpoint may remain as the valid setpoint.

s 2)

A more conservative setpoint may be calculated using the conservative Kr-89 total body dose factor.

This method may be use when there are no valid isotopics available.

The conservative setpoint will be calculated as follows:

12 count rate (CPM) above background of vent noble gas S

=

y monitor at the alarm setpoint level

PF' x D xR"

=

TB g

Where:

p oduct of allocation factor (AF) and safety factor PF'

=

=

=

=

g (Xe-133 detection, Kr-89 dose)

(3.53E-5) (60)

=

X7Q (X)(V)(K)

The setpoint calculation based on a Kr-89 skin dose is not required because the setpoint based on a Kr-89 total oody dose will always be more conservative.
