KRUSTY Experiment: Reactivity Insertion Accident Analysis

Reactivity of methacrylates in insertion polymerization.

Polymerization of ethylene by complexes [{(P^O)PdMe(L)}] (P^O = κ(2)-(P,O)-2-(2-MeOC(6)H(4))(2)PC(6)H(4)SO(3))) affords homopolyethylene free of any methyl methacrylate (MMA)-derived units, even in the presence of substantial concentrations of MMA. In stoichiometric studies, reactive {(P^O)Pd(Me)L} fragments generated by halide abstraction from [({(P^O)Pd(Me)Cl}μ-Na)(2)] insert MMA in a 1,2- as...

Comparative Analysis of Accident and Non-Accident Pilots

The purpose of this study was to investigate potential differences between two pilot groups; the first was a sample of individuals who have not been involved in an accident and the second was a sample of pilots from the National Transportation Safety Board (NTSB) accident database. Factors investigated included flight time, pilot flight review status, pilot certification, employment as a profes...

Applying STAMP in Accident Analysis∗

Accident models play a critical role in accident investigation and analysis. Most traditional models are based on an underlying chain of events. These models, however, have serious limitations when used for complex, socio-technical systems. Previously, Leveson proposed a new accident model (STAMP) based on system theory where the basic concept is not an event but a constraint. This paper shows ...

Monte Calrlo Modelling of Void Coefficient of Reactivity Experiment

The Atominstitute (ATI) of the Vienna University of Technology utilizes a TRIGA Mark II research reactor for last fourty eight years at a nominal reactor power of 250 kW (thermal). It has a completely mixed core and employing three different types of fuels i.e. aluminium clad fuel with 20% enrichment, stainless steel (SS) clad fuel with 20% enrichment and SS clad FLIP fuel with 70% enrichment. ...
