Nuclear Non-proliferation Import and Export Control Regulations — B.2.2
.2.2.8 All types of pressure transducers capable of measuring absolute pressure and having the following characteristics: (a) pressure sensing elements made of or protected by aluminium, aluminium alloy, aluminium oxide (alumina or sapphire), nickel or nickel alloys containing more than 60% nickel by weight, or fully fluorinated hydrocarbon polymers; (b) seals, if any, essential for sealing the pressure sensing element, and in direct contact with the process medium, made of or protected by aluminium, aluminium alloy, aluminium oxide (alumina or sapphire), nickel or nickel alloys containing more than 60% nickel by weight, or fully fluorinated hydrocarbon polymers; (c) either of the following characteristics: (1) a full scale of less than 13 kPa and an accuracy of better than ±1% of full scale; or (2) a full scale of 13 kPa or greater and an accuracy of better than ±130 Pa when measuring at 13 kPa. NOTE 1 Pressure transducers are devices that convert pressure measurements into an electrical signal. 2 For the purpose of this paragraph, accuracy includes non-linearity, hysteresis and repeatability at ambient temperature. B.2.2.9 Valves 5 mm (0.2 in.) or greater in nominal size, with a bellows seal, wholly made of or lined with aluminium, aluminium alloy, nickel, or alloy containing 60% or more nickel, either manually or automatically operated. NOTE For valves with different inlet and outlet diameters, the nominal size parameter above refers to the smallest diameter. B.2.2.10 Superconducting solenoidal electromagnets with all of the following characteristics: (a) capable of creating magnetic fields of more than 2 T (20 kilogauss); (b) with an L/D (length divided by inner diameter) greater than 2; (c) with an inner diameter of more than 300 mm; and (d) with a magnetic field uniform to better than 1% over the central 50% of the inner volume. NOTE This paragraph does not cover magnets specially designed for and exported as parts of medical nuclear magnetic resonance (NMR) imaging systems. It is understood that the wording “as part of” does not necessarily mean physical part in the same shipment. Separate shipments from different sources are allowed, provided that the related export documents clearly specify the “part of” relationship. B.2.2.11 Vacuum pumps with an input throat size of 38 cm (15 in.) or greater with a pumping speed of 15,000 L/s or greater and capable of producing an ultimate vacuum better than 10 4 torrs (1.33 x 10 -4 mbar). NOTE 1 The ultimate vacuum is determined at the input of the pump with the input of the pump blocked off. 2 The pumping speed is determined at the measurement point with nitrogen gas or air. B.2.2.12 Direct current high-power supplies capable of continuously producing, over a time period of 8 hours, 100 V or greater with current output of 500 amps or greater and with current or voltage regulation better than 0.1%. B.2.2.13 High-voltage direct current power supplies capable of continuously producing, over a time period of 8 hours, 20 000 V or greater with current output of 1 amp or greater and with current or voltage regulation better than 0.1%. B.2.2.14 Electromagnetic isotope separators, designed for or equipped with, single or multiple ion sources capable of providing a total ion beam current of 50 mA or greater. NOTES 1 This paragraph includes separators capable of enriching stable isotopes as well as those for uranium. A separator capable of separating the isotopes of lead with a one-mass unit difference is inherently capable of enriching the isotope of uranium with three-unit mass difference. 2 This paragraph includes separators with the ion sources and collectors both in the magnetic field and those configurations in which they are external to the field. 3 A single 50 mA ion source will produce less than 3 g of separated HEU per year from natural abundance feed. B.2.2.15 Bellows-sealed scroll-type compressors and bellows-sealed scroll-type vacuum pumps having all of the following characteris
