Hi buddy here I have come to get Excel File (dated March 2012) that having info status of NDA/RWMD work in responding to each of NWAA’s 101 issues, so would you plz tell me form where I can get it ??

As you asking here, I am providing Excel File (dated March 2012) showing the status of NDA/RWMD work in responding to each of NWAA’s 101 issues in Nuclear Waste Advisory Associates issues register. The table shows whether or not work is ongoing to address the issue, inactive or planned for future stages of the GDF process.

Raised Issues
Inadequate research exists on intermediate level waste wasteform lifetimes.
The relationship between waste form and repository design is a ‘major knowledge limitation’.
The selection of appropriate treatment for reactive metals is required.
A response to the ‘expansive fracturing’ that has taken place in waste packages in storage is required.
Work on container failure – specifically corrosion rates of steel and copper is required.
Research into mechanisms and probabilities of canister failure is required.
Particular problems due to new data on copper corrosion have arisen.
The impact of steel corrosion products on repository performance needs further work.
The interaction of repository components and the resultant impact on the safety case requires further research.
The interaction of waste fuel with other repository components requires further research.
The assumption that the corrosion of iron would use up the available oxygen must be demonstrated.
The impact of restoration on the facility is poorly known.
Proof is required that the ‘chemical containment’ approach put forward by nuclear industry would be effective in isolating waste.
It is difficult to predict the interaction of the glass of vitrified high level waste and clay.
The chemical, mechanical and flow behaviour of clay would be affected by the high temperature of high level waste.
Clay behaviour is difficult to quantify.
The capacity of clay to retain radionuclides can be damaged by salty or alkaline water.
Radionuclide retention by clay can also be damaged by corrosion products.
The impact of salty groundwater on repository/rock interaction is difficult to predict.
It is not clear what effects the chemicals in groundwater would have on the facility.
The development of methodologies for establishing flow over geographical regions.
Resolution of uncertainties in flow prediction.
