Fourth quarter of 1999
UK does not intend to return to foreign clients MOX production wastes
; UK Government Reply dated 11 November 1999 to a Question by MP Llew
WISE-Paris, 17 November 1999
Mr. Llew Smith:
To ask the Secretary of State for the Environment,
Transport and the Regions what quantities of plutonium contaminated
waste have been created to date in the production of MOX fuel for export
at Sellafield; and what arrangements exist for the storage or disposal
of plutonium contaminated radioactive wastes from MOX production. 
I have been asked to reply.
of total plutonium contaminated waste arisings at Sellafield to date
are provided in the 1998 UK Radioactive Waste Inventory which was published
in July 1999. I understand from BNFL that, to date, around 80 200-litre
drums of plutonium contaminated material can be attributed to the operation
of the MOX Demonstration Facility at Sellafield. It is not possible
to identify how much of this total amount is attributable to the production
of MOX for export.
understand that plutonium contaminated material at Sellafield will be
compacted, and then encapsulated, prior to storage and ultimate disposal
in an intermediate level waste facility. The latter will be subject
to a consultation which my right hon. Friend the Minister for the Environment
announced on 25 October.
