By June 1, 1985, a detailed study of the need for and feasibility of construction of one or more Monitored Retrievable Storage (MRS) facilities is required. The study is to include a proposal for the construction of one or more MRS facilities and to contain at least five alternative site-specific designs at a minimum of three different sites. 

An alternative to permanent isolation of the spent nuclear fuel is monitored, retrievable storage. This method has an advantage since, if reprocessing to remove potentially useful materials such as plutonium becomes feasible, the wastes are still accessible. The argument for this plan is that the technologies and alternatives available to society a few hundred years...

Archived electronic data are to be treated no differently to archived paper data. An archivist should be assigned, access should be limited to authorized personnel, data should be archived at the completion of the study, and all material should be indexed to permit expedient retrieval. Depending on the medium used for storage, an area within the facility may be needed with specific environmental controls to maintain the integrity of electronic data. This should be specified in the data storage SOPs. Environmental conditions need to be monitored in the archives where electronic media are stored. 

Promising new analytical tools are further enzymatic analysis, coated wire electrodes, high-pressure liquid chromotography, sulfide electrode use, and use of computers for data storage and retrieval and for monitoring laboratory instrumentation. 

Calculations were made for the initial and final states of the waste, and also year by year to show the impact of radioactive decay. Modelling of any short-term increases in hazard potential arising from retrieval, immobilisation and store management operations is outside the scope of the RHP, which is intended to be a measure of progress towards passively safe storage rather than a continuous hazard monitor . The RHP is normally calculated either annually or upon work-stream completion. 

Large Data Sets. We have discussed data acquisition problems that must be addressed, but we have not yet considered the question of managing the resultant data. The use of automated aerosol monitors and ancillary instruments will result in massive quantities of data. A typical 4-week experiment in which 10 parameters are monitored at 10-min intervals would require about 0.25 Mbytes of storage. The problems of data storage, organization, and retrieval are likely to be comparable to or greater than the difficulties of data analysis. 

A PACS is maintained by a server that provides storage, informatics, etc. for communication among members of the PACS, and also as many workstations as necessary to connect to the server. As already mentioned, at workstations one can retrieve reports and images of patients from the PACS and manipulate them to interpret as needed. A PACS is run by software designed for a particular operating system, such as Windows, Mac OS, Unix, or Linux, although most PACS workstations run on a PC platform. All PACS software can perform some standard functions, but ease of operation may vary. They differ at times in limitation of the number of the patient studies that can be displayed on a monitor screen. The software provides different protocols to access the PACS at the workstation. For example, a protocol may be based on a modality and body part combination, such as CT abdomen/pelvis, or on a secondary descriptor such as gallbladder stone...
