The monitoring of site specific parameters will be undertaken in conjunction with the monitoring that is required as part of the environmental management system for environmental protection purposes (see Chapter 14.4 of this PCSR). With regard to the SSA and other site specific criteria noted above, the parameters to be monitored should include, but not be restricted to ... 

As shown in Table 3.4, acceptance criteria for stabilization parameters may have a range of recommended values. Because some are more stringent than others, they should be used with caution and be adjusted as necessary based on the knowledge of site-specific conditions. For example, the criterion for turbidity of + 10 percent may be too stringent for some hydrogeological conditions or for the conventional sampling method. On the other hand, this criterion may be easily achieved for wells with dedicated submersible pumps and non-turbid, clear groundwater. 

Coastal processes (D2 - discretionary). This criterion relates to coastal erosion or other landscape changes. This criterion is site specific and is not addressed by the generic APIOOO design. Further consideration of this issue will be necessary at the site specific planning/design stages. 

On the other hand. Biggins examined various benzo-, naphtho- and anthraquinones and found a more stringent structural requirement for areplacement quinone to be functional at the A i site. It was specifically noted that among the many types of quinones, only naphthoquinones possessing a hydrocarbon chain at the 3-position, namely, 2-methyl-3-decyl-, 2-methyl-3-(isoprenyl)2- and 2-methyl-3-(isoprenyl)4-naphthoquinones, similar to phylloquinone with the 3-phytyl chain, could provide the required molecular structure for interaction with the hydrophobic domain at the A site, as confirmed by the criterion of P700 /P430 recombination kinetics. All other quinones presumably could oxidize Aq but the reduced quinone then recombined directly with P700. It was also noted that 2,3-dimethyl-1,4-naphthoquinone,... 

The specific steps in performing a reptation move are as follows. First, one end of the chain, either the head or the tail, is chosen randomly to be the lead end of the reptation. A site is then chosen randomly from the five, potentially available, nearest neighbors of the lead end (the sixth site is occupied hy the bead adjacent to the end and is not considered). If this site is vacant (i.e., not occupied by a bead from another chain), then the end is moved to this new site and all other beads of the chain follow the end otherwise, no move is made. Either way, the reptation move is completed, the new configuration is temporarily recorded, and the Monte Carlo acceptance criterion described above is used to determine whether this move is to be kept or not.
