MONTICELLO NUCLEAR GENERATING PLANT ODCM-APP-A TITLE: APPENDIX A Revision 1 Paqe 3 of 74 2.0

SUMMARY

OF DISPERSION CALCULATION PROCEDURES Updepleted, undecayed dispersion parameters were computed using the computer program XOQDOQ (Sagendorf and Goll, 1977). Specifically, sector average 1/Q 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 tenain 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 1/Q 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{erm 1/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 1/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 1/Q and D/Q values are used to conservatively represent short-term values. 1/Q and D/Q values for on-site EPA locations weri: adlusted (multiplied by a factcji of 0.238)Jo account for limited daily exposure of workers in accordance with NUREG-0473\'/.

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\") . Dispersion calculations for the reactor vent were based ort ATa2.7-16' and 10 meter wind data (1oint data recovery of 94 percent). Dispersion calculations for the offgas stack were based on ATroo-ro, and 100 meter wind data fioint data recovery of 95 percent).
