Geographic Information Systems (GIS) Evaluation of Proposed Savannah River Site L-Lake Drawdown

Description: L-Lake was created in 1985 to function as a once-through cooling water reservoir for L-Reactor at the Savannah River Site. The lake must be artificially maintained by pumping water from the Savannah River--at a significant annual cost. When L-Reactor was permanently shut down, studies were initiated to examine the ecological impact of a controlled L-Lake drawdown. An important part of these studies involved using GIS to develop a surface elevation model of the L-Lake floor based on side-scan so… more

Review of the ALOHA code pool evaporation model

Description: The ALOHA computer code determines the evaporative mass transfer rate from a liquid pool by solving the conservation of mass and energy equations associated with the pool. As part of the solution of the conservation of energy equation, the heat flux from the ground to the pool is calculated. The model used in the ALOHA code is based on the solution of the temperature profile for a one-dimensional semi-infinite slab. This model is only valid for cases in which the boundary condition (pool temper… more

Distribution of lake-bottom radionuclides measured with an underwater HPGe detector

Description: This study at Savannah River was done to assist decisions on the future of L Lake, an artificial reservoir made in 1983-5 for additional cooling for L Reactor discharges. EG&G overflight NaI mappings prior to filling indicated that most of the man-made radionuclides were {sup 60}Co and (predominantly) {sup 137}Cs in the earlier stream beds lying beneath the lake. An underwater HPGe was used in 1995 to rapidly scope the present radiation levels at 96 locations in the lake. The present levels are… more

Using Historical Aerial Photography and Softcopy Photogrammetry for Waste Unit Mapping in L Lake.

Description: L Lake was developed as a cooling water reservoir for the L Reactor at the Savannah River Site. The construction of the lake, which began in the fall of 1984, altered the structure and function of Steel Creek. Completed in the fall of 1985, L Lake has a capacity of 31 million cubic meters and a normal pool of 58 meters. When L Reactor operations ceased in 1988, the water level in the lake still had to be maintained. Site managers are currently trying to determine the feasibility of draining or … more

Experimental Model of the L-Area Outfall

Description: A once-through cooling lake has been chosen to provide for thermal mitigation of the reactor effluent cooling water. This alternative provides satisfactory cooling performance and thermal buffering, with moderate construction time, cost, and maintenance. In the event that the cooling lake fails to meet South Carolina environmental requirements during the summer months, SRP will reduce reactor power until supplemental cooling can be provided. To minimize this further expense and delay, it is des… more

Par Pond phytoplankton in association with refilling of the pond: Final Report for sampling from February 1995 -- September 1996

Description: This report describes the results of phytoplankton analyses from Par Pond samples collected between February 1995 and September 1996. The principal objective of the study was to determine the effect of refilling of Par Pond following repair of the dam on the phytoplankton community. Algal blooms are often responsible for fish kills and other detrimental effects in ponds and lakes, and it was postulated that decaying vegetation from formerly exposed sediments might trigger algal blooms that coul… more

Lagrangian and Control Volume Models for Prediction of Cooling Lake Performance at SRP

Description: The model validation described in this document indicates that the methods described here and by Cooper (1984) for predicting the performance of the proposed L-Area cooling lake are reliable. Extensive observations from the Par Pond system show that lake surface temperatures exceeding 32.2 degrees C (90 degrees F) are attained occasionally in the summer in areas where there is little or no heating from the P-Area Reactor. Regulations which restrict lake surface temperatures to less than 32.2 de… more

Interim report No. 2 on Production Test No. 105-17-P, Laboratory evaluation of proposed lubricants

Description: The lubricant (Calel A-60) used to reduce pushing forces when discharging slugs from pile tubes forms a cloudy emulsion with water. During the initial period of operation at 100 B and D areas, spillage of lubricant during discharge produced so much cloudiness in the basin water that it interfered with sorting operations. An investigation was started to see if a lubricant could be found that would effectively lubricate tubes during discharge and which would form optically clear systems when mixe… more
