tj NUCLEAR REGULATORY COMMISSION W ASHINGTON, D. C. 20555 March 29, 1988 HEMORANDUM FOR: Sholly Coordinator FROM: Lester S. Rubenstein, Director Standardization and Non-Power Reactor Project Directorate Division of Reactor Projects III, IV, Y and Special Projects

SUBJECT:

REQUEST FOR PUBLICATION IN BI-WEEKLY FR NOTICE - NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE AND PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION AND OPPORTUNITY FOR A HEARING Dairyland Power Cooperative, Docket No. 50-409, Lacrosse Boiling Water .

Reactor, Lacrosse, Wisconsin Date of amendment request: September 30, 1987 as revised February 22, 1988 Description of amendment request: The licensee proposes that License No.

DPR-45 for the Lacrosse Boiling Water Reactor (LACBWR) be amended to revise the Technical Specifications (TS).

License No. DPR-45 has been changed to possession-only status by a previous amendment. The proposed TS changes would remove most of the requirements for operational or refueling conditions, since the reactor is permanently shutdown and defueled. In some cases specifications with non-applicable operational conditions are modified or left unchanged since they interact with requirements'which are still applicable in the shutdown or defueled condition.

The possession-only license does not permit operational conditions of power operation, startup, hot shutdown, or refueling. Therefore, the license proposes to delete specifications for these conditions.

The licensee proposes to delete TS definitions and requirements related to core alteration, critical power ratio, cooling system leakage, limiting control red pattern, linear heat generation rate, partial scram, physics tests, 8804040265 080329 PDR ADOCK 05000409 P PDR 1

{

-2 pressure boundary leakage, shutdown margin and thermal power. These definitions and requirements are all related to reactor operation and are no longer applicable with no fuel in the reactor and reactor operations not permitted.

The licensee proposes to remove Safety Limits and Limiting Safety System Settings, and associated bases. These linits and trip setpoints were included to maintain the integrity of the fuel cladding, pressure vessel, and primary piping during abnormal reactor operating conditions and are not applicable

~

since the reactor is no longer operable or fueled.

The proposed TS would delete requirements for control room operator j direction of operations with fuel in the reactor and reactor operational instructions in the event of a tornado or high river water level. These operator requirements are not applicable with the reactor permanently shutdown. l The proposed TS would delete limiting conditions for operation (LCOs) that are applicable to reactor operations such as surveillance requirements for the reactor cooling system and associated valves, the electrical supply system 1 for reactor safety systems, and the post reactor accident instrunentation.

These TS requirements are not applicable when reactor operation is not permitted.

A new TS is proposed to specify additional requirements for the backup i 1

water supply for the Fuel Element Storage Well. This is an additional and l nore conservative requirement for this water supply. The licensee also pro-poses added TS requirements for Shift Supervisor authorization to perform any naintenance and for leak testing of the containnent freight door after each opening. These requirement are also more conservative than the existing TS.

1 x:

l Basis for proposed no significant hazards consideration determination: The Comission has provided standards for determining whether a significant A proposed amendment to an I hazards consideration exists (10 CFR 50.92(c)).

operating license for a facility involves no significant hazards consideration if operation and/or maintenance of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.

The licensee evaluated the proposed changes in accordance with the standards of 10 CFR 50.92(c) and determined that the proposed amendment would not:

1) involve a significant increase in the probability or consequences of an accident previously evaluated. The majority of changes and deletions are of itens that are related to reactor operations and ere no longer applicable.

These changes and deletions cannot affect the probability or consequences of any type of accident with the reactor permanently shutdown. Other changes which add additional requirements are more conservative and cannot increase the probability or consequence of any type of accident.

2) create the possibility of a new or different kind of accident from any accident previously evaluated. Since this proposed amendment consists of 1

deletion of requirements that don't apply with the reactor permanently shutdown or involves the addition of new requirements it doesn't affect the probability of any kind of accident. No new mode of operation is created by any of the changes in this package, and so the proposed amendment will not create the possibility of a new or different kind of accident from any previously evaluated.

f, .

t

3) involve a significant reduction in a margin of safety. Since the revisions proposed by this amendment consist of deleting requirements that don't apply or are not necessary with the reactor permanently shutdown and defueled, or consist of additional more conservative TS requirements the margin of safety will not be reduced.

Based on the above, the licensee has determined that the proposed amendment does not involve a significant hazards consideration. The NRC staff has reviewed the licensee's no significant hazards consideration determination and agrees with the licensee's analysis. Accordingly, the Comission proposes to determine that the requested amendment does not involve a significant hazards consideration.

I. INTRODUCTION AND

SUMMARY

This report describes the data accumulated in the Environmental Radiation Surveillance Program during the semiannual period January 1 through June 30, 1975.

Plant operation during the reporting period is detailed in a l

separate report entitled "Operating and Maintenance Semiannual Report No. 6". Power levels during this period were limited, administratively, to 80 percent of full power from February through May and 70 percent of full power during June. These limits on power level were set by Boston Edison Company for reasons of operation and maintenance. Plant capacity factors (a measure of electrical output) during the reporting period were:

January, 36 percent; February, 34 percent; March 76 percent; April, 42 percent; May, 55 percent; and June, 65 percent.

The Environmental Radiation Surveillance Program was implemented during the reporting period as required by the Nuclear Regulatory Commission. Plant-related radioactivity levels decreased from 1974 levels in molluscs, algae, and sediment. The current levels of Mn-54, Co-60 and Cs-137 in these media are less than 1 picoeurie per gram.

Weapons test fallout was detected in air particulates, specifically Nb-95, Ce-144 and Cs-137. These elements were also detected in various other media. Gaseous radio-iodine was detected onsite at 1

levels less than 1 picoeurie per cubic meter. This I-131 was attributed to releases from the reactor building vent.

Finally, marine media data from 1974 were reviewed and calcula-tions showed that the seafood ingestion dose to an individual was less than 1 millirem per year.

II. DESCRIPTION OF MONITORING PROGRM1 The Environmental Radiation and Radioactivity Su.veillance Program is being performed in accordance with the requirements specified in the Pilgrim Facility Operating License (DPP-35). Summaries i of the sampling media, locations, frequencies of collection, analyses and detection sensitivity are given in Tables 1 through

5. Sampling locations are shown in Figures 1, 2, and 3. Semi-annual Report No. 2 (August 29, 1973) describes the program in detail; however, the following discussion is provided to update that program description.

A. Atmospheric and Terrestrial Menitoring Beginning this reporting period airborne radiciodine levels are computed for each sample. Previously, samples with activities less than one picocurie per cubic meter were reported as "less than". The gaseous radiciodina sampling filters currently in use are activated charcoal impregnated felt (Barnaby Cheney "VA").

During this reporting period, the environmental dosimeters (TLD'a) were replaced with calcium sulphate (dysprosium) TLD's supplied by Teledyne Isotopes. The Teledyne "Radiguard" dosimeters provide four readout areas per location which are averaged after a one month exposure. The dosimeters are initially preselected by discarding those which lie outside a designated range following controlled irradiation. They are also calibrated by controlled 3

l - _ _ _ _ _ _ _ _

l irradiation each month. Typical accuracy is plus or minus three percent (90 percent confidence level). Sample collection in the atmospheric and terrestrial areas continues to be performed by Boston Edison Company personnel.

B. }iarine Monitoring Since July of 1973, an additional seawater sample has been taken monthly at a control location in Duxbury (see Figure 3). This is in addition to sampling of the intake and discharge canals and summer sampling of the area beaches.

The sampling of marine life continues to focus on species repre-senting pathways to man. That is, the sampling is focused on edible species (lar humans) including soft shelled clams, blue mussels, lobster, Irish moss and finfish. Shellfish, sediment and algae are sampled at shoreline locations by Battelle-Clapp Laboratories, Duxbury, Mass. Lobsters are collected from commer-cial lobstermen at the time the traps are hauled. The lobsters

'D taken weigh about 450 gms (age about 6 years). Finfish are caught in gill nets and otter trawls in the vicinity of the station by the Massachusetts Division of Marine Fisheries.

C. Radioactivity Analyses Laboratory analyses continue to be performed by Interex Corpora-tion, Natic. %ss, with analyses of selected media by Teledyne Isotopes, Westwood, N.J. Details of the laboratory procedures 4

can be found in Section G.1.5.2 of the Pilgrim 2 Environmental Report.( } The following are modifications of these procedures.

The analysis for gamma emitting isotopes (gamma spectrum) is done with a Ge (Li) spectrometer rather than by the radiochemical methods used prior to July 1974. The spectrometer has the advantages of detecting nearly all the gamma emitting isotopes in a single analysis and doing it non-destructively. This analy-sis effectively replaces the gross gamma analysis.

The radiochemical procedures used to measure strontium-89 and strontium-90 are those recommended in the NRC Regulatory Guide 4.6.

(1) Originally submitted to the AEC by Boston Edison Company in June 1973.

'2)The spectrometer at Interex is a Nuclear Data 4420 with a Princeton Gamma-Tech detector. Teledyne utilizes the Princeton Gamma-Tech /Tracor Northern (NS636 and TNll) systems.

III. MONITORING DATA AND RESULTS l

A. Air Surveillance l Weekly air surveillance samples were analyzed for gross beta l L activity and radiciodine activity. The results ere presented in Tables 6, 8 and 8A. Variations in radiciodine levels correlate to plant releases from the building vent (see Appendix A). These levels have a computed dose equivalent of 0.9 millirem to a con-tinuous occupant at the "warehouse" onsite location. The offsite radiciodine inhalation dose is less than 0.5 millirem. Monthly gross gamma results and quartecly gamma spectra are presented in -

Tables 7 and 7A respectively. These data show the presence of Nb-95, Cs-137 and Ce-144, typical of weapons test fallout. The April samples from Plymouth Center, Manomet, and pedestrian bridge (onsite) were reanalyzed with greater sensitivity and all showed the presence of Ce-144 and Cs-137. Comparisons of beta radio-activity with preoperational levels are shown in Figures 4 and 5.

B. External Gamma Exposure Rates During this reporting period Teledyne Radiguard TLD's were intro-duced into the program. Before phasing out the EGG TL-15 TLD's, overlapping data was obtained. Table 9 presents data taken with '

the TL-15 TLD's, Table 9A presents data taken with the Radiguard and also pret ents the ratios of the overlapping results. Ratios were also obtained at nine locations beginning July 1971. These 6

1 l

earlier ratios (Radiguard:TL-15) ranged from 0.60 to 0.86 and averaged 0.71. The combined January and February exposure reported in Table 9 was 6-e to inclement weather which persisted for several weeks.

C. Milk Milk was sampled from three locations and was analyzed monthly for Cs-137, Sr-90, Ba/La-140 and I-131. The results obtained during the reporting period are presented in Table 10. Tl levels of strontium and cesium measured in Plymouth milk do not exceed the levels measured prior to station operation, as shown in Figure 6.

D. Crops Commercial produce was sampled subsequent to the end of the reporting period and the results will be reported in the next report.

E E. Domestic and Recreational Water Monthly composites of weekly water samples were analyzed for l gross radioactivity and the isotopes H-3, Sr-90 and I-131. Re-sults are shown in Table 12. The May sample from Manomet Well was reanalyzed to check the anomolous tritium recult and the result was verified. Althc.gh the activity remains unexplained, it is 1/100th of the level permitted by Federal Regulations (10CFR20 App. B). The next sample taken in June contained no l detectable tritium.

. . . ~ . .. - - .. .-~ -- . .

i F. Precipitation A precipitation collection station in Plymouth, five miles from the plant, was sampled during the reporting period. The radio-activity found in the monthly samples is reported in Table 13.

G. Seawater Monthly samples were taken from the intake channel, discharge channel, and a control location 7.5 miles NNW of the station.

These were ana]yzed for fractional gross beta (explained in Table 14), gross gamma, tritium and iodine-131. The results of these analyses and of quarterly analyses of intake and discharge sea-water are presented in Table 14.

H. Marine Life The results of Ge (Li) and Sr-89, 90 analyses of marine life samples are presented in Table 15. Missing values indicate incomplete analyses and will be reported in a lat* report.

Several samples carried over from the previous reporting period showed plant-related radioactivity. Two Atlantic cod contained low levels of Mn-54, Co-60, Zn-65 and Cs-137. Out of a sampling of ten bluefish, one group of two contained Co-58 and Co-60 activity. This radiocobalt can probably be attributed to one cobalt particle ingested by one of the fish. (Plant discharges are filtered through a 109 filter.)

Finfish (pollock, flounder) from the reporting period showed no plant-produced radioactivity except low levels of Cs-137. This  ;

nuclide is present due to weapons test fallout (see Table 7A) and was detected in finfish before the plant began operation.

Irish moss (Chondrus crispus) and rockweed (Ascophyllum nodosum) s sampled in the vicinity of the station showed plant-related radio-activity-(Mn, Co, Zn, Cs). No plant-related nuclides were detected at the control location, Ellisville, except Ce-144, which can be attributed to weapons test fallout (see Table 7A), and Be-7, a cosmic ray produced nuclide.I }

Plant-related activity was not found in clams (Mya arenaria) but was found in mussel., (Mytulis edulis) taken from - area of the discharge breakwater only. These mussels containe. low levels of Mn-54 and Co-60.

i l

Radiation doses to humans resulting from these levels of radio- ,

activity will be discussed in the next report. The results of dose calculations using 1974 marine life data is presented in Section IV.

IV. 1974 SEAFOOD INGESTION DOSES Estimation of doses to man from marine life' ingestion pathways were made in Report No. 5 and presented in Table 18 of that report. These have been modified as follows, and are presented in Table 17.

Samples taken in 1974, found t'o contain plant-related nuclides

~

were grouped by species, and activities-were averaged. These mean activities were converted to ingestion doses using Draft Regulatory Guide 1.AA. These doses were then averaged among all species within each of the four groups: fish, crustacea, molluscs and algae. The averaging is done to maintain consumption rates of 18 kg/yr for fish, 9 kg/yr for mollucc and crustacea, and 0.73 kg/yr for algae.

Table 17 shows that seafood ingestion doses resulting from 1974 liquid releases totaling 4.2 curies were much less than 1 mrem / year to an average individual.
