چکیده انگلیسی

Uncertainty and sensitivity analysis results obtained in the 1996 performance assessment for the Waste Isolation Pilot Plant are presented for two-phase flow in the vicinity of the repository under undisturbed conditions. Techniques based on Latin hypercube sampling, examination of scatterplots, stepwise regression analysis, partial correlation analysis and rank transformations are used to investigate brine inflow, gas generation, repository pressure, brine saturation, and brine and gas outflow. Of the variables under study, repository pressure is potentially the most important due to its influence on spallings and direct brine releases, with the uncertainty in its value being dominated by the extent to which the microbial degradation of cellulose takes place, the rate at which the corrosion of steel takes place, and the amount of brine that drains from the surrounding disturbed rock zone into the repository.

مقدمه انگلیسی

Uncertainty and sensitivity analysis results for fluid flow in the vicinity of the repository under undisturbed conditions obtained as part of the 1996 performance assessment (PA) for the Waste Isolation Pilot Plant (WIPP) are presented. A following paper will present results for disturbed conditions [1]. The results under study were calculated with the BRAGFLO program [2] for the three replicated Latin hypercube samples (LHSs) (i.e. R1, R2, R3) described in Ref. [3, Eq. (7)]. In particular, the results under consideration are the outcomes of the 300 E0 BRAGFLO calculations indicated in Ref. [4, Table 6]. The topics considered are brine inflow (Section 2), gas generation (Section 3), pressure (Section 4), brine saturation (Section 5), and brine and gas outflow (Section 6). In each section, a number of results calculated by BRAGFLO are examined with sensitivity analysis techniques based on examination of scatterplots, partial correlation coefficients, and stepwise regression analysis [5, Section 3.5]. The sensitivity analyses make extensive use of rank-transformed data [6], the STEPWISE program [7] and [8] for stepwise regression analysis, and the PCCSRC program [9] and [10] for the calculation of partial correlation coefficients. The specific BRAGFLO results considered are listed in Table 1, which can be used to obtain exact definitions of the individual variables under consideration; further, the uncertain analysis inputs are described in Ref. [3, Table 1]. Table 1.

Similarly, summaries of uncertainty based on box plots will also use all 300 observations. In contrast, distributions of time-dependent results will typically be shown for only replicate R1 to avoid the presentation of plots with so many individual curves that they are unreadable. However, mean and percentile curves Ref. [11, Section 5] will typically be obtained from all 300 observations. The results in this presentation were obtained in support of the U.S. Department of Energy's (DOE's) compliance certification application (CCA) for the WIPP [12] and are based on material contained in Ref. [13, chap. 7].
