RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Revision 7 ODCM-07.01 MONTICELLO NUCLEAR GENERATING PLANT TITLE:
Page 3 of 24 I/plr 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.
RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Revision 7 ODCM-07.01 MONTICELLO NUCLEAR GENERATING PLANT TITLE:
Page 4 of 24 I/plr 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 (LIQUID EFFLUENTS) Control 1.2.1.A, ODC-M-03.01 (GASEOUS EFFLUENTS) 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.
RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Revision 7 ODCM-07.01 MONTICELLO NUCLEAR GENERATING PLANT TITLE:
Page 5 of 24 I/plr 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.
RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Revision 7 ODCM-07.01 MONTICELLO NUCLEAR GENERATING PLANT TITLE:
Page 6 of 24 I/plr 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.
RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Revision 7 ODCM-07.01 MONTICELLO NUCLEAR GENERATING PLANT TITLE:
Page 7 of 24 I/plr 2.4 Interlaboratory Comparison Program 2.4.1 Controls A.
Analyses SHALL be performed on radioactive materials supplied as part of an NIST traceable 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.
RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Revision 7 ODCM-07.01 MONTICELLO NUCLEAR GENERATING PLANT TITLE:
Page 8 of 24 I/plr 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 10CFR 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.
