Palisades Nuclear Plant Semiannual ~'

Radioactive Effluent Release Report January - June 1988 .

.This report provides information relating to radioactive ef fluent releases and sclid radioactive waste processing at the Palisades Nuclear Plant during the period of January through June 1988. The report format is detailed in Plant i Technical Specification 6.9.3.la. Palisades has been on-line during this ,

reporting period since being returned to service January 27, 1988.

1. Supple 3 ntal Information A. Batch Releases .

i

'Information relating to batch releases of gaseous and liquid -

effluents is provided in Table HP 10.5-1.  !

B. Abnornal Releases  :

LER-PAL 88-002 On February 9, 1988 at 1630 an Auxiliary Operator (AO) identified I that the in-service waste gas decay tank (WCDT) T-68C (WEITK] had lost approximately 26 pai. The gas from the WCDT was released into the Auxiliary Building (NF] and ultimately to the atmosphere via the monitorea Plant stack. The gaseous release from the in-service tank is contrary to Technical Specification (TS) 3.24.6.1 which states, "the WCDT system shall be used to reduce radioactive gaseous effluents by holding gaseous waste collected by the system for a minimum of 15 days up to 60 days".

  • During the event, 6.032 curies of noble gas as Xe-133 were released over a period totaling one hour. The release was averaged over a one hour period resulting in an MPC fraction of 8.0E-3 at the site  ;

boundary. This value is a small portion of the one maximum permissible concentration fraction allowed at the site boundary.

The release was monitored by Plant stack radiation monitoring equipment. No alarms or annunciations were received in the Control Room due to the highest count rate seen being a factor of approximately five below the alert alarm setpoint. Therefore, due to the insignificant dose consequence, no adverse effects were 1 presented to the general public.

2. Caseous Effluents '

Table HP 10.5-2 lists and summarizes all gaseous radioactive effluents released during the reporting period. The unidentified beta was 1.13E-06% of the total release. -

3. Liquid Effluents -

Table HP 10.5-3 lists and summarizes all liquid radioactive ef fluents released during the reporting period. There was no unidentified beta released. '

4. Solid Waste Solid radwaste classif cation, sources, volume shipped, curie and nuclide '

content are detailed in Table HP 10.5-4. All radwaste shipments were made to either Barnwell, South Carolina or Richland, Washington for.

burial.  ;

5. Summary of Radiological Impact on Man Potential doses to individuals and populations were calculated using i CASPAR and LADTAP computer program codes. The first and second quarter values for curies released were input for each nuclide and summarized as followst A. The maximum offsite air dose at the site boundary due to noble gases was 3.30E-02 millirad beta and 1.11E-02 millirad gamma for the first

' L' quartert and 4.72E-02 millirad beta and 1.59E-02 millirad gamma for the second quarter. .

B. The most restrictive organ dose to an individual in an unrestricted area (b'a sed on identified critical receptors) f rom gaseous ef fluents <

(tritium, particulates and lodine) was the infant thyroid. Doses were 9.01E-03 and 8.24E-03 millirem for the first and second quarters, respectively.

C. Integ -;-e i .nal body doses to the general population and average doses , a viduals (adults) within the population f rom gaseous effluent , oses within a distance of 50 miles from the site i boundary e.rs: 1.73E-02 manRem and 1.65E-05 millires for the first quartert and 2.12E-02 manRem and 2.02E-05 millirem for the second quarter.

D. The maximum total body dose to an individual (adult) in unrestricted water - related exposure pathways was 4.54E-03 and 2.67E-03 millirems for the first and second quarters, respectively. The maximum organ doses were 7.90E-03 millires (teenage bone) for the first quarter and 4.42E-03 millirem (teenage liver) for the second quarter.

E. . Integrated total body doses to the general population and average dosts to individuals (adults) within the population from liquid '

effluent releases within a distance of 50 miles from the site boundary were: 1.63E-02 manRem and 1.55E-05 millirem for the first -

quartert and 1.02E-02 manRem and 9.71E-06 millirem for the second ,

q ua rt e r .

, F. Both the Selenium-75 present in the gaseous effluent releases and the entrained noble gases present in the liquid releases (first and I second quarters) were not significant in either wholebody or organ doses.

6. Process Cont rol Program (PCP)

There were no changes to the PCP during the reporting period. .

7. Of f site Dose Calculation Manual (ODCM)

There were no changes to the ODCM during the reporting period.

8. Supplemental Information for the July-December 1987 Semiannual 5 Radioactive Effluent Release keport l

' The Palisades Nuclear Plant Semiannual Radioactive Effluent Release Repo rt i July - December 1987, Tables HP 10.5-2 Caseous Effluents and Tables HP 10.5-3 Liquid Ef fluents are being submitted as an attachment with the following revisions:

Item 2 - Caseous Effluentst change from "the unidentified beta was 4.09E-05% of the total release" to "the unidentified beta was 4.10E-05%" of the total release".

Item 3 - Liquid Effluents: change from "the~ unidentified bets was 4.60E-03% of the tstal release" to "the unidentified oeta was 4.46E-03% of the total release".

Raasons for the above data revisions to the Palisades Semi-Annual Radio-at ti ve Ef fluent Release Report, July - December 1987 was that the calcu '

la:ed Sr-89 and Sr-90 release quantities (gaseous and liquid effluents.

4th Quarter only) were based on estimated values for the months of November and December. Teledyne Isotcpve Midwest Laboratory had not yet completed the actual sample analyses priae to the Technical Specification-Semi Annual Report due date. All dats. changes are indicated by "#" in the right-hand margins. There were no significant dose changes to the i public.
