H. FORDOW FUEL ENRICHMENT PLANT
44. The Fordow Fuel Enrichment Plant (FFEP) will be converted into a
nuclear, physics, and technology centre and international collaboration will be
encouraged in agreed areas of research. The Joint Commission will be informed
in advance of the specific projects that will be undertaken at Fordow.
45. Iran will not conduct any uranium enrichment or any uranium
enrichment related R&D and will have no nuclear material at the Fordow Fuel
Enrichment Plant (FFEP) for 15 years.
46.
For 15
years, Iran will maintain no more than 1044 IR-1 centrifuge machines at one
wing of the FFEP of which:
46. Two cascades that have not experienced UF6 before will be
modified for the production of stable isotopes. The transition to stable
isotope production of these cascades at FFEP will be conducted in joint
partnership between the Russian Federation and Iran on the basis of
arrangements to be mutually agreed upon. To prepare these two cascades for
installation of a new cascade architecture appropriate for stable isotope
production by the joint partnership, Iran will remove the connection to the UF6
feed main header, and move cascade UF6 pipework (except for the dump line in
order to maintain vacuum) to storage in Fordow under IAEA continuous
monitoring. The Joint Commission will be informed about the conceptual
framework of stable isotope production at FFEP.
46. For four cascades with all associated infrastructure remaining
except for pipework that enables crossover tandem connections, two will be
placed in an idle state, not spinning. The other two cascades will continue to
spin until the transition to stable isotope production described in the
previous subparagraph has been completed. Upon completion of the transition to
stable isotope production described in the previous
subparagraph, these two
spinning cascades will be placed in an idle state, not
spinning.
47. Iran will:
47. remove the other 2 cascades of IR-1 centrifuges from this wing,
by removing all centrifuges and cascade UF6 pipework, including sub headers,
valves and pressure transducers at cascade level, and frequency inverters.
47. also subsequently remove cascade electrical cabling, individual
cascade control cabinets and vacuum pumps. All these excess centrifuges and
infrastructure will be stored at Natanz in Hall B of FEP under IAEA continuous
monitoring.
48. Iran will:
48. remove all excess centrifuges and uranium enrichment related
infrastructure from the other wing of the FFEP. This will include removal of
all centrifuges and UF6 pipework, including sub headers, valves and pressure
gauges and transducers, and frequency inverters and converters, and UF6 feed
and withdrawal stations.
48. also subsequently remove cascade electrical cabling, individual
cascade control cabinets, vacuum pumps and centrifuge mounting blocks. All
these excess centrifuges and infrastructure will be stored at Natanz in Hall B
of FEP under IAEA continuous monitoring.
49. Centrifuges from the four idle cascades may be used for the
replacement of failed or damaged centrifuges in stable isotope production at
Fordow.
50. Iran will limit its stable isotope production activities with
gas centrifuges to the FFEP for 15 years and will use no more than 348 IR-1
centrifuges for these activities at the FFEP. The associated R&D activities
in Iran will occur at the FFEP and at Iran's declared and monitored centrifuge
manufacturing facilities for testing, modification and balancing these IR-1
centrifuges.
51. The IAEA will establish a baseline for the amount of uranium
legacy from past enrichment operations that will remain in Fordow. Iran will
permit the IAEA regular access, including daily as requested by the IAEA,
access to the FFEP in order to monitor Iran's production of stable isotopes and
the absence of undeclared nuclear material and activities at the FFEP for 15
years.
I. OTHER ASPECTS OF ENRICHMENT
52. Iran will abide by its voluntary commitments as expressed in its
own long term enrichment and enrichment R&D plan to be submitted as part of
the initial declaration described in Article 2 of the Additional Protocol.[1] The IAEA will confirm on an
annual basis, for the duration of the plan that the nature and scope and scale
of Iran's enrichment and enrichment R&D activities are in line with this
plan.
53. Iran will start to install necessary infrastructure for the IR-8
at Natanz in Hall B of FEP after year 10.
54. An agreed template for describing different centrifuge types
(IR-1, IR-2m, IR-4, IR-5, IR-6, IR-6s, IR-7, IR-8) and the associated
definitions need to be accomplished by implementation day.
55.
An
agreed procedure for measuring IR-1, IR-2m and IR-4 centrifuge performance data
needs to be accomplished by implementation day.
