Creating and Editing Progeny Chains in FRAMES: A Workshop Overview

DESCRIPTION

This workshop, hosted by the U.S. Nuclear Regulatory Commission at the Pacific Northwest National Laboratory, focused on constructing site-specific constituent degradation chains using the FRAMES 2.0 platform. Participants learned to navigate the Database Editor for existing databases, manipulate chemical properties, and visualize degradation chains. Key objectives included illustrating degradation pathways, from TCE to degradation products, and enhancing user skills in database management for environmental assessments.

  1. EXAMPLEFRAMES ConstituentDatabase Editor (CDBE): Creating/Editing a Progeny Chain FRAMES-2.0 Workshop U.S. Nuclear Regulatory Commission Bethesda, Maryland November 15-16, 2007 Pacific Northwest National Laboratory Richland, Washington

  2. Purpose • Construct/Design site-specific, constituent degradation/decay chains • Illustrated the construction of TCE 1,1-DCE VC 2

  3. Open an Existing Constituent Database(outside of FRAMES) Two Options (choose one): • Use the Windows Start button • Start • All Programs • FRAMES • Launch Constituent Editor • Run C:\FramesV1\ContSel.exe 3

  4. 3 1 • Database Editor User Interface appears • Choose File and Open • Choose an Exiting database: FUI_TCE.mdb 2 4

  5. Do not select Constituents of Concern; first, choose Edit Constituent Properties 1 5 3 2 4 • Lists Constituents in Database • Identification: Identifies Constituent, and controls its disposition. • Properties: Provides physical/chemical properties of chemical • Degradation Products: Creates/Edits degradation chain of chemical. • Degradation Chain: Provides a summary of the degradation chain 5

  6. Chemicals are listed alphabetically. • CASID numbers are listed in numerical order. • The highlighted chemical name does • NOT necessarily correspond to the • highlighted CASID. 1 2 6

  7. Straight Degradation Chain 7

  8. Parent Chemical: TCE • TCE Progeny: 1,1-DCE (100%) • Parent Chemical: 1,1-DCE • 1,1-DCE Progeny: VC 1 2 3 4 8

  9. 1. Summary of Degradation Chain (straight chain degradation) 2. New progeny listing under Select Constituents of Concern 3. Save FUI_TCE.mdb 1 Same 2 3 9

  10. To remove the progeny chain, choose <none>. 10

  11. Branching Degradation Chain 11

  12. BranchingDegradationChain A 1 2 B C • A. TCE branches to • 1,2-Dichloroethylene trans (78%) • 1,1-Dichloroethylene (22%) • B. 1,2-Dichloroethylene trans degrades to VC • C. 1,1-Dichloroethylene degrades to VC 12

  13. 1 2 Under the Degradation Chain tab: 1. Straight Degradation identifies the predominate degradation chain 2. Branch Degradation identifies all chains 13
