Application of a simple parameter estimation method to predict effluent transport in the Savannah River

A simple parameter estimation method has been developed to determine the dispersion and velocity parameters associated with stream/river transport. The unsteady one dimensional Burgers' equation was chosen as the model equation, and the method has been applied to recent Savannah River dye tracer studies. The computed Savannah River transport coefficients compare favorably with documented values, and the time/concentration curves calculated from these coefficients compare well with the actual tr… more

Analysis of Iodine-129 in aqueous samples by inductively coupled plasma-mass spectrometry

An inductively coupled plasma - mass spectrometry (ICP-MS) method was developed to determine the [sup 129]I content in aqueous environmental samples. Due to interference from xenon, direct measurement of [sup 129]I could not be made on the ICP-MS. An ion-exchange technique is used to concentrate the Iodine from one liter samples to 30 mL. The 30 mL eluant from the anion-exchange column is then introduced to the ICP-MS. The detection limit of the procedure is [le]O.5 pCi/L. Several samples from … more

Savannah River Plant seismograph network

The network consists of three field seismometer sites (SRPN, SRPW, SRPD) and one central recording station. The seismic activity at each field site is detected by a seismometer, which is a movable coil that induces a series of electric impulses when vibrated. These electrical impulses are amplified and sent over telephone lines to a central recording site, where the signals are again amplified and then recorded by a heated stylus on heat-sensitive paper. The signals from sites SRPN and SRPW are… more

Dynamic limits of error for inventory differences at the Savannah River Site

Limits of error for inventory differences (LEIDs) using variance propagation techniques have been discussed in previous INMM meetings. However, using the variance propagation methodology with a large number of actual inventory measurements on a monthly basis requires the use of an automated LEID program and a means of inputting the data into the program. Currently, there is no standard program being used at DOE facilities. A standard program should be flexible and easy to use but general enough… more

Statistical analysis of inhibitor concentrations for radioactive waste in carbon steel tanks

Based on a logistic regression approach, a model was developed using the explanatory variables log([NO{sub 3}{sup {minus}}]), log([NO{sub 2}{sup {minus}}]), and temperature to estimate the probability of pitting in a carbon steel exposed to high-level radioactive waste. Pitting susceptibility data obtained by the two techniques of cyclic potentiodynamic polarization and coupon immersion were separately and jointly analyzed with the model. Similar predictive ability is seen for equations based o… more

An introduction to geographic information systems as applied to a groundwater remediation program

While the attention to environmental issues has grown over the past several years, so has the focus on groundwater protection. Addressing the task of groundwater remediation often involves a large-scale program with numerous wells and enormous amounts of data. This data must be manipulated and analyzed in an efficient manner for the remediation program to be truly effective. Geographic Information System`s (GIS) have proven to be an extremely effective tool in handling and interpreting this typ… more

Remote video radioactive process evaluation, Savannah River Site

Specialized miniature low cost video equipment has been effectively used in a number of remote, radioactive, and contaminated environments at the Savannah River Site (SRS). The equipment and related techniques have reduced the potential for personnel exposure to both radiation and physical hazards. The valuable process information thus provided would not have otherwise been available for use in improving the quality of operation at SRS.

Critical heat flux concerns during the flow instability phase of a DEGB LOCA

Arguments are presented that support the proposal that a separate burnout risk analysis, for the Flow Instability (FI) phase of a LOCA, not be required for reactor restart. With expected reactor power limits, flow instability will occur before critical heat flux (CHF). Since FI power limits preclude the occurrence of flow instability in a bounding accident, a DEGB LOCA, the risk of CHF and attendant burnout is negligible. A review of RDAP data revealed that in the past reactor assemblies operat… more

Increased hydrogen release from a Savannah River Site high-level waste storage tank due to sparging: Measurement and modeling results

During normal operations at the Savannah River Site (SRS), tanks containing high-level radioactive waste are continuously ventilated to prevent accumulation of hydrogen gas within the vapor space. However, during some maintenance operations, the ventilation is temporarily halted. During a 1990 ventilation outage, hydrogen accumulated in a tank vapor space much more rapidly than expected. The accelerated rate of hydrogen evolution was traced to an air sparge within the tank solution which signif… more

Performance degradation of a large production reactor recirculation pump during off-design conditions

In order to accurately predict reactor hydraulic behavior during a hypothetical Loss-of-Coolant-Accident (LOCA) the performance of reactor coolant pumps under off-design conditions must be understood. The LOCA of primary interest for the Savannah River Site (SRS) production reactors involves the aspiration of air into the recirculated heavy water flow as reactor tank inventory is lost, (system temperatures are too low to result in significant flashing of water coolant into steam). Entrained air… more

Hydrogen generation in SRAT with nitric acid and late washing flowsheets

Recently, SRTC recommended two process changes: (1) a final wash of the tetraphenylborate precipitate feed slurry and (2) the use of nitric acid to neutralize the sludge in the SRAT. The first change produced an aqueous hydrolysis product (PHA) with higher formic acid/formate and copper concentration, and reduced the nitrate content in the PHA by an order of magnitude. The second change is to substitute part of formic acid added to the SRAT with nitric acid, and therefore may reduce the hydroge… more
