Title: Effectiveness of Bronze as a Zinc Getter After Being Subjected to Simulated Exposures

Abstract

We report that gamma-emitting zinc-65 was detected in piping contained in a tritium glovebox after a vacuum thermal process. This contaminate was created during irradiation of components in a nuclear reactor and was borne of natural zinc. The Tritium Extraction Facility prefers to capture the zinc in a high radiation area to minimize potential dose to the worker and to reduce the likelihood of spreading contamination to other areas of the facility. Previous efforts have shown that bronze is an excellent candidate material to act as a zinc getter in the as-fabricated condition. In reality, the extraction process may contain moisture and hydrogen which could cause oxidation or reduction of the surfaces of the zinc getters. A series of experiments was conducted to determine the efficacy of the zinc getters after oxidation and reduction exposures. Lastly, it was determined that the bronze coupons were moderately effective in most of the oxidized conditions and in all the oxidized and reduced conditions.

EFFECT OF THERMAL PROCESSES ON COPPER-TIN ALLOYS FOR ZINC GETTERING

Technical Report Korinko, P. ; Golyski, M.

A contamination mitigation plan was initiated to address the discovery of radioactive zinc‐65 in a glovebox. A near term solution was developed, installation of heated filters in the glovebox piping. This solution is effective at retaining the zinc in the currently contaminated area, but the gamma emitting contaminant is still present in a system designed for tritium beta. A project was initiated to develop a solution to contain the {sup 65}Zn in the furnace module. Copper and bronze (a Cu/Sn alloy) were found to be candidate materials to combine with zinc‐65 vapor, using thermodynamic calculations. A series of binary Cu/Snmore »« less

Bronze Alloy Development for Zinc Vapor Capture

Journal Article Korinko, Paul S. - Journal of Failure Analysis and Prevention

After gamma-emitting ⁶⁵Zinc was detected in a vacuum pumping system contained in a tritium glovebox, a series of experiments were undertaken to develop a method and material to trap zinc vapors in an area that is more suitable for preventing dose to workers. In this study, bronze alloys with 0–30% tin were prepared using a powder metallurgical process and exposed to three levels of zinc vapors. Furthermore, all of the alloys demonstrated acceptable zinc gettering capacity; however, low tin content bronzes are considered for further testing.

Effectiveness of copper and bronze for zinc capture

Technical Report Korinko, P. S.

A series of experiments was conducted to determine the efficacy of using copper and bronze sheet and screen under high vacuum conditions to capture zinc vapor. The experiments were conducted in a parametric manner using a fixed zinc vaporization temperature (350°C) but varying the filter temperature from ambient to 550°C. Consistent with previous work, metallic zinc was deposited at low temperatures, but the deposit was non-adherent. At an intermediate temperature range (350-450°C), the deposit formed an alloy with both copper and bronze materials. At higher temperatures (> 500°C) the zinc did not deposit on the surfaces likely due to itsmore »« less

SUMMARY REPORT FOR ZINC 65 CONTAMINATION CONTROL

Technical Report Korinko, P.

Radioactive zinc, {sup 65}Zn, was detected after extraction of 215 TPBARs in from TVA reactor fuel cycle 6. A team consisting of Tritium Engineering, Tritium Operations, Tritium Radiation Control, and Savannah River National Laboratory personnel evaluated the risk and response and developed short, medium and long term goals for contamination control. One of the goals was incorporated into site Performance Based Incentive CO 3.4, to optimize the filter geometry and operating conditions for the Tritium Extraction Facility. This goal included a scoping study to determine if the contamination could be contained within the high radiation environment of the furnace modulemore »« less

Design, fabrication, and testing of a getter-based atmosphere purification and waste treatment system for a nitrogen-hydrogen-helium glovebox

Journal Article Bibeault, M. L. ; Paglieri, S. N. ; Tuggle, D. G. ; ... - Fusion Science and Technology

A system containing a combination of getters (Zr-Mn-Fe, SAES St909; and Zr{sub 2}Fe, SAES St198) was used to process the nitrogen-hydrogen-helium atmosphere in a glovebox used for handling metal tritide samples. During routine operations, the glovebox atmosphere is recirculated and hydrogenous impurities (i.e. CQ{sub 4}, Q{sub 2}O, and NQ{sub 3}, where Q =H, D, T) are decomposed (cracked) and removed by Zr-Mn-Fe without absorbing elemental hydrogen isotopes. If the tritium content of the glovebox atmosphere becomes unacceptably high, the getter system can rapidly strip the glovebox atmosphere of all hydrogen isotopes by absorption on the Zr{sub 2}Fe, thus lessening themore »« less
