SOURCES Page 3 of 4 2.0 DOSE FROM ALL URANIUM FUEL CYCLE SOURCES 2.1 Dose Commitment 2.1.1 Controls A.

In accordance with T.S.6.8.D.1 0, the dose or dose commitment to any member of the public from all uranium fuel cycle sources is limited to less than or equal to 25 mrem to the total body or any organ, except for the thyroid, which SHALL be limited to less than or equal to 75 mrem over a period of 12 consecutive months.

2.1.2 Applicability At all times 2.1.3 Action A.

With the calculated dose from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of Controls ODCM-02.01 Section 2.2.1, ODCM-03.01 Section 2.2.1 or ODCM-03.01 Section 2.3.1, prepare and submit within 30 days a special report to the Commission which includes the following:

1.

Defines corrective actions and calculates the highest radiation exposure to any member of the general public from all uranium fuel cycle sources (including all effluent pathways and direct radiation).

2.

Unless this report shows that exposures are less than the 40CFR Part 190 standard, either apply to the Commission for a variance to continue releases which exceed the 40CFR Part 190 standard or reduce subsequent releases to permit the standard to be met.

2.1.4 Surveillance Requirements A.

Cumulative dose contributions from all liquid and gaseous effluents SHALL be determined in accordance with surveillance requirements ODCM-02.01 Section 2.2.4, ODCM-03.01 Section 2.2.4, and ODCM-03.01 Section 2.3.4 and in accordance with the ODCM.

SOURCES Page 4 of 4 2.2 Bases 2.2.1 Dose From All Uranium Fuel Cycle Sources A.

Dose Commitment Control 2.1.1.A. is provided to meet the dose limitations of 40CFR190. The specification requires the preparation and submittal of a special report whenever the calculated doses from plant radioactive effluents exceed twice the design objective doses of Appendix I. Submittal of the report is considered a timely request and a variance is granted until Staff action on the request is complete. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to a real individual will exceed 40CFR1 90 if the individual reactors remain with the reporting requirement level. For the purpose of the special report it may be assumed that the dose commitment to the real individual from other uranium fuel cycle source is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 5 miles must be considered.

RADIOLOGICAL ENVIRONMENTAL Revision 2 MONITORING PROGRAM Page 3 of 24 2.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 2.1 Monitoring Program 2.1.1 Controls A.

In accordance with T.S.6.8.A, the Radiological Environmental Monitoring Program (REMP) SHALL be conducted as specified in Table 1.

B.

Radioanalysis SHALL be conducted meeting the requirements of Table 3.

2.1.2 Applicability At all times.

2.1.3 Action A.

Whenever the Radiological Environmental Monitoring Program is not being conducted as specified in Table 1 the Annual Radiological Environmental Operating Report SHALL include a description of the reasons for not conducting the program as required and plans for preventing a recurrence.

B.

Deviations are permitted from the required sampling schedule if samples are unobtainable due to hazardous conditions, seasonable unavailability, or to malfunctions of automatic sampling equipment. If the latter occurs, every effort SHALL be made to complete corrective action prior to the end of the next sampling period.

I/plr

MONTICELLO NUCLEAR GENERATING PLANT ODCM-07.01 TITLE:

RADIOLOGICAL ENVIRONMENTAL Revision 2 MONITORING PROGRAM Page 4 of 24 C.

With the level of radioactivity in an environmental sampling medium exceeding the reporting levels of Table 2 when averaged over any calendar quarter, submit a special report to the Commission within 30 days from the end of the affected calendar quarter. When more than one of the radionuclides in Table 2 are detected in the sampling medium, this report SHALL be submitted if:

concentration (1) concentration (2)

+---------

+

+... >1.0 limit level (1) limit level (2)

When radionuclides other than those in Table 2 are detected and are the result of plant effluents, this report SHALL be submitted if the potential annual dose to an individual is equal to or greater than the calendar year limits of ODCM-02.01 Control 1.2.1.A, ODC-M-03.01 Control 1.2.1.A, or ODCM-03.01 Control 1.3.1.A.

This report is not required if the measured level of radioactivity was not the result of plant effluents; however, in such an event, the condition SHALL be reported and described in the Annual Radiological Environmental Operating Report.

D.

Although deviations from the sampling schedule are permitted under Paragraph B. above, whenever milk or leafy green vegetation samples can no longer be obtained from the designated sample locations required by Table 1, the Annual Radiological Environmental Operating Report SHALL explain why the samples can no longer be obtained and identify the new locations which have been or will be added to and deleted from the monitoring program.

2.1.4 Surveillance Requirements The radiological environmental monitoring samples SHALL be collected pursuant to Table 1 from the specific locations in Table 4 and SHALL be analyzed pursuant to the requirements of Table 1 and the detection capabilities required by Table 3.

I/plr

MONTICELLO NUCLEAR GENERATING PLANT ODCM-07.01 TITLE:

RADIOLOGICAL ENVIRONMENTAL Revision 2 MONITORING PROGRAM Page 5 of 24 2.2 Land Use Census 2.2.1 Controls A Land Use Census SHALL be conducted and SHALL identify:

A.

The location of the nearest milk animal, the nearest residence, and the nearest garden of greater than 500 ft2 producing fresh leafy vegetables in each of the 16 meteorological sectors within a distance of 5 miles.

B.

The location of ALL milk animals and ALL 500 ft2 or greater gardens producing broad leaf vegetation in each of the meteorological sectors within a distance of 3 miles.

2.2.2 Applicability At all times.

2.2.3 Action A.

With a Land Use Census identifying a location which yields a calculated dose or dose commitment (via the same exposure pathway) 20 percent greater than at a location from which samples are currently being obtained in accordance with Controls 2.1.1.A., the Annual Radioactive Effluent Release Report for this period SHALL identify the new location. The new location SHALL be added to the Radiological Environmental Monitoring Program within 30 days. The sampling location, excluding the control station location, having the lowest calculated dose or dose commitment (via the same exposure pathway) may be deleted from this monitoring program after October 31 of the year in which this Land Use Census was conducted.

2.2.4 Surveillance Requirements A.

The Land Use Census SHALL be conducted at least once per year between the dates of May 1 and October 31 by door to door survey, aerial survey, or by consulting local agricultural authorities associations.

I/plr

MONTICELLO NUCLEAR GENERATING PLANT ODCM-07.01 TITLE:

RADIOLOGICAL ENVIRONMENTAL Revision 2 MONITORING PROGRAM Page 6 of 24 2.3 Sampling Table 1 and Figure 1 specify the current sampling locations for the radiation environmental monitoring program. These sampling locations are based on the latest land use census.

If it is learned from an annual census that milk animals or gardens are present at the location which yields a calculated thyroid dose greater than those locations previously sampled, the new milk animal or garden locations resulting in the higher calculated doses SHALL be added to the surveillance program as soon as practicable. Sample locations (except the control) having lower calculated doses may be dropped from the program at the end of the grazing or growing season (October 31) to keep the total number of sample locations constant.

If the plant begins routine discharges of liquid radioactive effluent into the Mississippi River, a land use survey will be conducted to determine whether any crops are irrigated with water taken from the Mississippi River between the plant discharge canal and a point 5 miles downstream. If edible crops are being irrigated from Mississippi River water, appropriate samples will be collected and analyzed per Table 1.

I/plr

MONTICELLO NUCLEAR GENERATING PLANT ODCM-07.01 TITLE:

RADIOLOGICAL ENVIRONMENTAL Revision 2 MONITORING PROGRAM Page 7 of 24 2.4 Interlaboratory Comparison Program 2.4.1 Controls A.

Analyses SHALL be performed on radioactive materials supplied as part of an NRC approved cross-check program. This program involves the analyses of samples provided by a control laboratory and comparison of results with those of the control laboratory as well as with other laboratories which receive portions of the same samples. Media used in this program (air, milk, water, etc.) SHALL be limited to those found in the Radiological Environmental Monitoring Program.

2.4.2 Applicability At all times.

2.4.3 Action A.

When required analyses are not performed, corrective action SHALL be reported in the Annual Radiological Environmental Operating Report.

2.4.4 Surveillance Requirements A.

The summary results of analyses performed as part of the above required program SHALL be included in the Annual Radiological Environmental Operating Report.

I/plr

MONTICELLO NUCLEAR GENERATING PLANT ODCM-07.01 TITLE:

RADIOLOGICAL ENVIRONMENTAL Revision 2 MONITORING PROGRAM Page 8 of 24 2.5 Bases 2.5.1 Monitoring Program Control 2.1.1 provides measurements of radiation and radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures of individuals resulting from the plant operation. This program thereby supplements the radiological effluent monitoring by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. After a specific program has been in effect for at least 3 years of operation, program changes may be initiated based on this experience.

The detection capabilities required by Table 1 are state-of-the art for routine environmental measurements in industrial laboratories. The LLDs for drinking water meet the requirement of 40CFR Part 141.

2.5.2 Land Use Census Control 2.2.1 is provided to ensure that changes in the use of off-site areas are identified and that modifications to the monitoring program are made if required by the results of this census. The best survey information from door-to-door, aerial or consulting with local agricultural authorities SHALL be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 1 OCFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20% of the garden was used for growing broad leaf vegetation (i.e.,

similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/square meter.

2.5.3 Sampling Section 2.3, paragraph 3, is worded to conform to LAR-39 and its associated NRC Safety Evaluation (SER).

2.5.4 Interlaboratory Comparison Program The requirement for participation in an interlaboratory comparison program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of a quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

SUMMARY

OF DISPERSION CALCULATION PROCEDURES Updepleted, undecayed dispersion parameters were computed using the computer program XOQDOQ (Sagendorf and Goll, 1977). Specifically, sector average yJQ and D/Q values were obtained for a sector width of 22.5 degrees. Credit was taken for momentum plume rise and effective plume height was adjusted for local terrain height for elevated releases. Building wake corrections were used to adjust calculations for ground-level releases. Standard open terrain recirculation correction factors were also applied as available as default values in XOQDOQ.

Dispersion calculations were based on mixed mode releases for the reactor vent and on elevated releases for the offgas stack. A summary of release conditions used as input to XOQDOQ is presented in Table 1 and controlling site boundary distances are defined in Table 2. Computed XJQ and D/Q values for unrestricted area boundary locations (relative to release points) and for standard distances (to five miles from the source in 0.1 mile increments) are presented in Tables 3 through 11.

For certain meteorological and release conditions, the enveloping interpolation routines in XOQDOQ used to compute short-term X/Q and D/Q values do not provide reasonable results. Because of this, results were reviewed for consistency and where possible, the distributions of calculated X/Q values were enveloped and interpolated by hand.

In some cases, use of the NRC methodology is implemented in XOQDOQ for estimating short term dispersion values results in values which are lower than the annual values. For these cases, the annual average x/Q and D/Q values are used to conservatively represent short-term values. x/Q and D/Q values for on-site EPA locations were adjusted (multiplied by a factor of 0.238) to account for limited daily exposure of workers in accordance with NUREG-0473(2).

On-site meteorological data for the period September 1, 1976 through August 31,1978 (as presented in Appendix B) were used as input to XOQDOQ. Data were collected and AT stability classes were defined in conformance with NRC Regulatory Guide 1.23(3). Dispersion calculations for the reactor vent were based on AT42.7-10m and 10 meter wind data (joint data recovery of 94 percent). Dispersion calculations for the offgas stack were based on AT100-.1om and 100 meter wind data (joint data recovery of 95 percent).
