Based on the EPR, ENDOR, ESEEM and some other spectroscopic results models for Yz function in PS II have been developed (see references 385, 386 for recent reviews). There seems to be consensus that this amino acid is involved in proton-coupled electron-transfer. As proton acceptor His (Dl-190) was identified which is also found to be close to Yz in the recent X-ray structure.19 The postulated direct involvement of Yz in the water splitting process as a hydrogen atom abstractor or in separate or coupled proton/electron-transfer is still controversially discussed.385 386...

Tennessee. He worked on the processing and fabrication of fresh and irradiated nuclear fuels materials at Oak Ridge National Laboratory and at the General Atomic Company for 20 years. For the past five years he has done conceptual and bench-role process design for hydrogen production processes, principally for thermochemical water-splitting processes. 

The sulfur-iodine (S-I) cycle is a thermochemical water-splitting process that utilizes thermal energy from a high-temperature heat source to produce hydrogen (H2). It is comprised of three coupled chemical reactions, as shown in figure 4.1. First, the central low-temperature Bunsen reaction (Section I) is employed to produce two... 

In tire hydrogen production by nuclear heat, there is the limitation by thermodynamic law (the Carnot efficiency at the highest), because either the electrolysis or the thermochemical water splitting process has to go through the "heat engine path. 

Recent evaluations have shown hydrogen can be produced with high efficiency, safely, economically, and without the emission of greenhouse gases using the modular helium reactor (MHR) coupled to the SI thermochemical water splitting process and HTE [2]. These concepts are referred to as the Sl-based H2-MHR and the HTE-based H2-MHR, respectively, and are described in this paper.
