TC05: Waste Vitrification


TC05 is concerned with Nuclear and Hazardous Waste Vitrification. The vision and mission of the committee are as follows: 1) to establish a forum to present, discuss and disseminate technical information on waste glass chemistry, vitrification processes, vitrification melter technologies, and waste glass environmental performance. 2) to facilitate the dissemination of technical information through promoting programming at technical conferences, conducting technical workshops and facilitating publication of information through established channels. Promoting the exchange of technical data is also a goal of this committee.

2016 report

TC05 conference for 2016 and next year –general considerations

It is suggested to identify at least two conferences per year including a session focus on Nuclear and hazardous Waste Vitrification. Ideally one per continent is a good objective.

The interest is to create a focus on these conferences to create well attended sessions on TC05 activities and good exchange between experts. These conferences are a good opportunity to gather the present TC05 members in a specific meeting. The attendance of TC05 meeting can be extended to designated representatives of missing TC05 members or invited experts. The objective of these meetings is to share information about congress and international initiative in the field of waste glass. It is expected that thanks to a good network this information will be widespread in the institutions concerned by these subjects. It would be nice if a volunteer TC05 member who is present at the conference can support the organization of the meeting and write short minutes.

Conference including session dealing with TC05 activities in 2016

5- 8 september 2016 ESG-SGT conference - Sheffield :

The conference had about 400 attendees.  There were 6 sessions. One session was organized by TC05.  In the TC05 sessions, there were about 50 oral presentations and 10 posters.  The sessions were very well attended with generally over 50 attendees at TC05 sessions. 

23 - 27 October 2016 - MS&T 2016 Salt Lake City

27 November – 2 December 2016 - MRS Fall Meeting Boston

Upcoming conference including possible session dealing with TC05 activities in 2017

2015 report

A primary objective for 2015 was to organize and conduct technical programming at the ACerS GOMD/DGG conference in Miami and PACRIM 11 in Jeju Island.

At the ACerS GOMD/DGG conference, there were 8 sessions organized and sponsored by TC05.  In the 8 sessions, there were 46 oral presentations (1 withdrawn) and 7 posters.  The sessions were very well attended with over 75 attendees at several of the sessions.  At the conference, there was also an international workshop on corrosion of waste glasses that was supported by TC05. At the GOMD/DGG conference TC05 member Bill Ebert presented a paper discussing a round robin study of the Product Consistency Test (PCT) procedure sponsored by the U.S. Department of Energy. Four of the five institutions supporting the study were associated with TC05. A two days international glass corrosion workshop was held following the ACerS GOMD/DGG conference. 30 participants took part in this workshop dealing with fundamental understanding of nuclear waste corrosion over geological time scales. As part of this international collaboration over 20 institutions across the world are currently performing corrosion tests with the International Simple Glass (ISG) promoted by TCO5 members. The ISG is a six component glass designed to simplify waste glass compositions and provide a standard glass for international testing. SRNL (a TCO5 representative institution) acts as custodian of the ISG and distributes to institutions. A journal article is planned to summarize testing with the ISG.

 

At the PacRim conference 15 oral presentations and 5 posters dealing with TC05 activities were presented. Six countries were represented by speakers in these sessions.

 

The proceedings from the "2nd international summer school on nuclear glass waste form: Structure, Properties and Long-Term Behavior (SumGLASS 2013)" held in Vers-Pont-du-Gard, France from 23 – 27 September 2013 was published in 2015. Procedia Materials Science Volume 7. It includes about forty articles several of which were authored by TC05 members.

 

After 9 years spent as chairman of the TC05, Jim Marra turned over chairmanship to Olivier Pinet at the end of September 2015. Beyond his kindness, we recognize the work he performed to link the scientific community in the field of waste vitrification.

 

PLANS AND DELIVERABLES FOR 2016

The primary objective for 2015 will be to organize and conduct technical programming to continue to further TC05’s mission to facilitate the dissemination of technical information. Due to continued travel restrictions for most TC05 members, it was determined that conducting programming at least two meetings located in two different continents would provide the most benefit to TC05 members and the technical community at large.

 

Therefore, TC05 is planning to organize a TC05 session at Glass and Optical Materials Division Meeting (GOMD) in Madison, WI USA from 22 to 26 of May. It was agreed that programming should continue to be aligned with the international glass corrosion workshop since this results in strong attendance and presentations. Dialog with Joe Ryan, PNNL, (lead organizer for the international corrosion workshops) will continue to coordinate TC05 programming with the corrosion workshop. A TC05 session will be organized at ESG/SGT meeting that will be held at the University of Sheffield from 5 to 9 September. This event marks the Society of Glass Technology's centenary anniversary, which will be held alongside the European Society of Glass's annual conference.

 

Other opportunities for meetings on nuclear and hazardous waste vitrification will be:

 

  • The MRS meeting in December 2016 in Boston, MA USA.The MRS meeting will commemorate the 40th anniversary of the “Scientific Basis for Radioactive Nuclear Waste Management” symposium series.
  • MS&T Conference in October 2016 in Salt Lake City, UT, USA.

 

In 2016, TC05 will also work to update and provide new information on the website in an effort to improve communications and promote TC05 activities.

Liquidus temperature (TL) round-robin study

Eight institutions from four countries participated in a round-robin study to determine the precision and bias of a liquidus temperature (TL) procedure for waste glasses being adopted by ASTM International as ASTM C 1720-11. In this study, three separate TL measurement methods were employed: a gradient temperature (GT) method, a uniform temperature (UT) method, and a crystal fraction extrapolation (CF) method. The TL was measured for three glasses of complex formulations based on borosilicates. The temperature ranges of reported TL values for the primary crystalline phases (spinel, zircon, and rare-earth borosilicate) were sufficiently narrow and consistent between the various methods used to consider the standard deviation of a TL measurement as ±9.5°C to 16°C, ±7°C to 8°C, and ±8°C to 13°C for the GT, UT, and CF methods, respectively.
