Appendix CRF - Part 3 - Northamptonshire County Council

I5 How much radioactive waste do you intend to accumulate?
• Where one or a few radionuclides dominate the waste you should detail each of them.
• You must detail all alpha-emitting radionuclides.
• If you use just a few megabecquerels of similar radionuclides, you can list them as a group.
Examples could be ‘Tritium/Carbon 14’ or ‘total other radionuclides excluding alpha emitters’. This will
give you flexibility.
Radionuclide Maximum activity in becquerels
I6 What is the maximum volume you intend to accumulate at any one time?
Disposal of aqueous waste
Cubic metres
I7 Do you intend to dispose of radioactive aqueous waste?
Yes Please continue with the rest of this section
No Please go to next section
I8 What is the chemical and physical nature of the waste you intend to dispose of?
The aqueous waste will be leachate collected from the operating landfill and will have the
chemical properties typically associated with landfill leachate from a hazardous waste site. The
leachate could conceivably contain leached radioactivity.
I9 How do you intend to measure or estimate the activity of the discharge? Please explain
The maximum activity of the discharge has been estimated for risk assessment purposes in Application for “
Disposal of LLW including HV-VLLW Under the Radioactive Substances Act 1993, for the East Northants
Resource Management Facility, Supporting Information. The estimate is based upon conservative assumptions
for overall risk assessment purposes. The actual amount of the discharge is uncertain and will depend on the
actual amount of waste disposed in the void at any one time and the fraction of the inventory which transfers to
the leachate. The activity in the leachate will be monitored.
I10 Where will you dispose of the radioactive aqueous waste?
Please tick all that apply and answer the questions in the relevant section.
to a public sewer
direct to a watercourse or water body
to your premises’ own sewage treatment works
other method(s) Leachate is currently tankered to an offsite treatment works
Disposal to a public sewer
I11 What is the name of your sewerage undertaker?
I12 What is the OS national grid reference of the sewage treatment works discharge point?
For example SJ 123 456
