Igneous Consequence Modeling for the TSPA-SR
The purpose of this technical report is to develop credible, defendable, substantiated models for the consequences of igneous activity for the TSPA-SR Model. The effort will build on the TSPA-VA and improve the quality of scenarios and depth of the technical basis underlying disruptive events modeling. Computational models for both volcanic eruptive releases (this is an event that results in ash containing waste being ejected from Yucca Mountain) and igneous intrusion groundwater releases (this is an event that reaches the repository level, impacts the waste packages, and produces releases from waste packages damaged by igneous activity) will be included directly in the TSPA calculations as part of the TSPA-SR Model. This Analysis Model Report (AMR) is limited to development of the conceptual models for these two scenarios. The mathematical implementation of these conceptual models will be done within the TSPA-SR Model. Thus, this AMR will not include any model results or sensitivity analyses. Calculation of any doses resulting from igneous releases will also be done within the TSPA-SR model, as will the probabilistic weighting of these doses. Calculation and analysis of the TSPA-SR Model results for igneous disruption are, therefore, outside the scope of this activity. The reason for not running the mathematical models as part of this AMR is that the models are integrated within the TSPA-SR model and, thus, any model simulations and the corresponding results are out of the scope of this AMR. The scope of this work as defined in the development plan (CRWMS M&O 2000j) involves using data that has been extracted from existing sources to design and support the TSPA-SR models for the transport of radionuclides following igneous disruption of the repository. The development plan states ''applications of the code in this analysis will be limited to testing of the code and sensitivity analyses during analysis design.'' In contrast to the development plan, the ASHPLUME code is not run within this AMR and any sensitivity runs will be performed within the TSPA-SR. This change has no impact on the technical output from this AMR. The objectives of the work are to: (1) Develop TSPA-SR conceptual models for volcanic eruptive and igneous intrusion groundwater transport releases from igneous activity consistent with the available conceptual models and data; (2) Document support from conceptual models and data; (3) Deliver conceptual model parameter inputs to the TSPA-SR Model; (4) Provide appropriate documentation for conceptual models, data, and parameters to relevant project databases; and (5) Recommend an appropriate mathematical model for the volcanic eruption release scenario and provide appropriate parameter values for this model which will be run within the TSPA-SR Model.
