Operational Regulations Governing Nuclear Safeguards Article 2

Definitions of terminologies used in this Regulations are as follows:1. Nuclear safeguards materials are classified below:i. Uranium or uranium-containing materials; uranium-containing materials refers to materials with a weight percentage of uranium no less than 0.05%.ii. Plutonium or plutonium-containing materials.iii.Thorium or thorium-containing materials; thorium-containing materials refers to materials with a weight percentage of thorium no less than 0.05%.iv. Deuterium or deuterium-containing materials: deuterium, heavy water (deuterium oxide), or other deuterated compounds that are used in a nuclear reactor and have been imported or exported consecutively for 12 months, which weigh more than 200 kg and have a weight percentage of deuterium and hydrogen nuclei no less than 0.02%.v. Those materials other than the above four types designated by the competent authorities to be included as nuclear safeguards materials.2. Effective kilogram, a special unit in weight used in safeguarding nuclear materials of uranium (including enriched uranium, natural uranium, or depleted uranium), plutonium, or thorium, is calculated based on the following computation formulas:i. Uranium with a weight percentage in the uranium-235 isotope of 1% or above, the quantity in effective kilograms is the product of the Uranium weight in kilograms multiplied by the square of the weight percentage in the uranium-235 isotope.ii. Uranium with a weight percentage in the uranium-235 isotope of between 1% and 0.5%, the quantity in effective kilograms is the product of the Uranium weight in kilograms multiplied by 0.0001.iii.Uranium with a weight percentage in the uranium-235 isotope of below 0.5%, the quantity in effective kilograms is the product of the Uranium weight in kilograms multiplied by 0.00005.iv. Uranium containing uranium-233, the computation formulas for effective kilograms are the same as those for uranium-235.v. Plutonium, the quantity in effective kilograms is its weight in kilograms.vi.Thorium, the quantity in effective kilograms is the product of its weight in kilograms multiplied by 0.00005.3. Nuclear safeguards facilities are defined as follows:i. Research, power generation, or other nuclear reactor facilities.ii.Production or storage facilities for nuclear source materials or nuclear fuels; facilities for management, storage, or final disposal of spent fuel.iii.Facilities storing nuclear safeguards materials in excess of one effective kilogram or any other locations designated by the competent authorities.
中文原文 核子保防作業辦法第2條
本辦法用詞,定義如下:
一、核子保防物料,指下列各目之一者:

(二)鈽或含鈽之物料。
(三)釷或含釷之物料;含釷之物料指含有釷之成分重量比在萬分之五以上者。
(四)氘或含氘之物料:指用於核子反應器,且在連續十二個月內輸入或輸出之氘、重水(氧化氘)及其他氘化合物,其重量超過二百公斤且氘原子與氫原子之重量比在萬分之二以上者。
(五)前四目以外,其他經主管機關指定應列入核子保防物料者。
二、有效公斤:指鈾(包括濃縮鈾、天然鈾或耗乏鈾)、鈽或釷按下列方法計算所得之重量。
(一)鈾二三五同位素重量比在百分之一以上之鈾:係以公斤為單位之鈾重量與鈾二三五同位素重量比平方之乘積。
(二)鈾二三五同位素重量比在千分之五以上未滿百分之一之鈾:係以公斤為單位之鈾重量乘以萬分之一。
(三)鈾二三五同位素重量比未滿千分之五之鈾:係以公斤為單位之鈾重量乘以十萬分之五。
(四)鈾二三三之有效公斤計算方法與鈾二三五相同。
(五)鈽係以公斤為單位之鈽重量。
(六)釷係以公斤為單位之釷重量乘以十萬分之五。
三、核子保防設施指下列各目之一者:
(一)研究用、動力用或其他核子反應器設施。
(二)核子原料、核子燃料生產或貯存設施,用過核子燃料之處理、貯存或最終處置設施。
(三)任何存有一有效公斤以上核子保防物料之場所或其他經主管機關指定之場所。
