2. Unirradiated separated plutonium in the course of manufacture or fabrication and plutonium contained in unirradiated semi-fabricated or unfinished products at fuel or other fabricating plants or elsewhere	0.8 (0.8)
3. Plutonium contained in unirradiated MOX fuel or other fabricated products at reactor sites or elsewhere	1.9 (1.9)
4. Unirradiated separated plutonium held elsewhere.	1.5 (1.5)
Total	126.3 (123.0)
Note
1. Plutonium included in lines 1-4 above belonging to foreign bodies.	23.0 (23.4)
2. Plutonium in any of the forms in lines 1-4 above held in locations in other countries and therefore not included above	0.0 (0.9)

Estimated amounts of plutonium contained in spent civil reactor fuel - United Kingdom

National totals as of 31 December 2014	(Previous year's figures in brackets) Rounded to 1000 kg plutonium with quantities less than 500 kg reported as such Tonnes
1. Plutonium contained in spent fuel at civil reactor sites	8 (8)
2. Plutonium contained in spent fuel at reprocessing plants.	22 (23)
3. Plutonium contained in spent fuel held elsewhere.	Less than 500 kg (Less than 500 kg)

The treatment of material sent for direct disposal will need further consideration when specific plans for direct disposal have taken concrete form.

Line 1: Covers estimated amounts of plutonium contained in fuel discharged from civil reactors;
Line 2: Covers estimated amounts of plutonium contained in fuel received at reprocessing plants but not yet reprocessed.

National totals as of 31 December 2014	(Previous year's figures in brackets)
1. HEU stored at enrichment plants	0 kg (0 kg)
2. HEU at fabricating plants or at other reprocessing facilities	348 kg (342 kg)
3. HEU at civil reactor sites	0 kg (0 kg)
4. HEU at locations other than civil reactor sites, enrichment fabricating and reprocessing plants (e.g. laboratories, research centres)	913 kg (914 kg)
