Title: Downstream extent of the N Reactor plume

Abstract

The downstream extent of the N Reactor thermal plume was studied to assess the potential for fisheries impacts downstream of N Reactor. The N Reactor plume, as defined by the 0.5/sup 0/F isotherm, will extend less than 10 miles downstream at river flows greater than or equal to annual average flows (120,000 cfs). Incremental temperature increases at the Oregon-Washington border are expected to be less than 0.5/sup 0/F during all Columbia River flows greater than the minimum regulated flows (36,000 cfs). The major physical factor affecting Columbia River temperatures in the Hanford Reach is solar radiation. Because the estimated temperature increase resulting from N Reactor operations is less than 0.3/sup 0/F under all flow scenarios, it is unlikely that Columbia River fish populations will be adversely impacted.

    The U.S. Department of Energy was issued a National Pollutant Discharge Elimination System (NPDES) permit for operation of the N Reactor discharge from December 7, 1981, through December 31, 1985. Part 1.A.9 (Effluent Limitations, Monitoring Requirements, and Schedule of Compliance) states in part that a detailed low-flow receiving-water study be conducted to document the extent and nature of the existing outfall discharge plume. Pacific Northwest Laboratory conducted a two-phase program to characterize the N Reactor thermal plume. The work was performed for UNC Nuclear Industries, Inc., the operator of N Reactor for the U.S. Department of Energy (DOE). Part Imore » of this report deals with the field studies to characterize the N Reactor thermal plume, performed September 15 through 20, 1982. It includes a description of the study area, a description of field tasks and procedures, and data collection results and discussion. The field studies consisted of a bathymetric survey, underway thermal surveys, dye dispersion surveys, and vertical velocity measurements. Part II is the computer simulation of the thermal plume under different flow conditions and the calibration of the model used. It includes a description of the computer model and the assumptions on which it is based, a presentation of the input data used in this application, and a discussion of modeling results. The model is used to predict the effects of the discharged heated water on downstream river temperatures for flow conditions from 36,000 cubic feet per second (cfs) to 300,000 cfs. Figures called out in the text of this report are found at the end of each section.« less

    Pacific Northwest Laboratories (PNL) performed field and modeling studies -from March 1982 through June 1983 to characterize the thermal plume from the N Reactor heated water outfall while the N Reactor operated in the Pu-only mode. Part 1 of this report deals with the field studies conducted to characterize the N Reactor thermal plume while in the Pu-only mode of operation. It includes a description of the study area, a description of field tasks and procedures, and data collection results and discussion. Part 2 describes the computer simulation of the thermal plume under different flow conditions and the calibration ofmore » the model used. It includes a description of the computer model and the assumptions on which it is based, a presentation of the input data used in this application, and a discussion of modeling results. Because the field studies were restricted by the NPOES permit variance to the spring months when high Columbia River flows prevail the mathematical modeling of the N Reactor thermal plume while the reactor operates in the Pu-only mode is instrumental in characterizing the plume during low Columbia River flows.« less

    Interest in burning crude oil as a means to mitigate large scale oil spills at sea led to mid-scale evaluation of relevant crude oil burning characteristics. As part of this effort, a computer-based field measurement technique for estimating the size, shape, and extent of visible smoke plumes was developed. Of the experiments in which measurements were made, Test 7 provided data on plume trajectory for the largest distance from the pan. Good agreement was obtained between corresponding 35 mm photographs and digitized images used to estimate plume volume and trajectory. In Test 7, at 600 s after ignition, the leadingmore » edge of the smoke plume had risen to 750 m and traveled 1800 m downwind from the pan. The estimated total volume of the smoke plume at 600 s after ignition was 3.8 x 10(exp 8)cum. At that time, the total volume of the smoke plume was increasing at a rate of 3.2 x 10(exp 6)cum/s. Limited evaluation indicates that the MS-DOS based method provides reasonably accurate estimates of visible smoke plume geometry in the near-field. Field accuracy depends on plume size, wind speed and direction, and the resolution of the equipment.« less
