This document explains the U.S. Department of Energy's (DOE) position under the Standard Compliance method of DOE's Alternative Fuel Transportation Program (the Program; 10 C.F.R. Part 490) regarding alternative fuel vehicle (AFV) credit for covered fleet acquisitions of light-duty plug-in hybrid electric vehicles (PHEVs).
A method for independent real and reactive power flow control without sensing receiving end voltage in a power flow controller (PFC) includes calculating a first reference phase angle, calculating a first reference voltage, modifying the first reference phase angle calculated using a first phasor modifier, calculating a first reference current for a first terminal, calculating a second reference phase angle for current through the first terminal, calculating a second reference voltage across a second CMI by subtracting voltages at the first terminal and a second terminal, and controlling the first CMI and the second CMI for controlling the power flow through the PFC.

The International Criticality Safety Benchmark Evaluation Projects (ICSBEP) has over two decades of experience under the auspices of the Organisation for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) to identify, evaluate, and compile a comprehensive data set of criticality safety benchmark data [1]. The activities of the ICSBEP have led to the continued success of the International Handbook of Evaluated Criticality Safety Benchmark Experiments (ICSBEP Handbook) [2]. The contents of the ICSBEP Handbook include benchmark specifications derived from nuclear facilities around the world, which have been utilized to support criticality safety efforts and also integral testing of nuclear data [3]. The 2020 edition of the ICSBEP Handbook will include data from 582 evaluations containing benchmark specifications for 5,053 critical, subcritical, or near-critical configurations. There are seven criticality-alarm-placement/shielding evaluations containing a total of 45 benchmark configurations, and ten fundamental physics evaluations containing a total of 237 measurements relevant to criticality safety applications. The purpose of this paper is to summarize those benchmarks relative to validation needs in shielding applications currently found within the ICSBEP Handbook. The current and future plans of shielding benchmarks with regards to the ICSBEP will also be discussed.
