摘要： A spacer for a fuel bundle is disclosed in which a grid type construction provides an approximation to a traditional ferrule spacer. First and second sets of diagonally extending strips of Zircaloy are utilized extending along opposite diagonals across a square sectioned spacer. One set of strips is disposed in a first parallel array along a first diagonal, with each strip of the set being spaced from other strips of the set at rod width spaced intervals along the second and remaining diagonal. The other set of strips is disposed in a second parallel array along an second diagonal, with each strip of the set being spaced from the other strips of the set at rod width spaced intervals along the first diagonal. The strips of both arrays are bent in a zigzag configuration as they extend diagonally across each fuel bundle with successive legs defined between bends in the strip including a diagonal leg, a horizontal leg, a diagonal leg (in the same diagonal direction), and a vertical leg with the secession being repeated to form the required diagonal length. The diagonal elements are provided with opposing protruding tabs, these tabs defining interlocking cell boundaries diagonally around each individual fuel rod. The strips are engaged one towards another with the opposed protruding tabs interleaved to connect the diagonally extending strips together into a mutually interlocking grid. There results an eight sided cell around each fuel rod with the tabs of the strips along a first diagonal forming first opposite diagonal cell boundaries, the tabs of strips along the second diagonal forming second opposite diagonal cell boundaries, and the horizontal and vertical legs closing the eight sided cell between the cell diagonals.

摘要： This is a process for producing material for lining reactor fuel element claddings. Rather than using unalloyed zirconium, this invention provides for an alloy liner for the cladding. The process uses ultra-slow electron beam melting of zirconium, to give very low metallic impurities to reduce solid solution strengthening and second phase formation and property variability from lot to lot, while using alloying to reduce the susceptibility to steam corrosion. Oxygen is controlled to a very low level as well, and preferably only 0.1-0.4 tin is added to provide a low, but fabricable, hardness in the alloyed liner material.

摘要： The invention relates to a method of producing a zirconium alloy semi-finished product for the production of an elongated product and to the use thereof. According to the invention, a large ingot (1) is produced by means of zirconium alloy casting and, subsequently, the ingot is forged in order to produce the semi-finished product (3) in two steps. The first ingot (1) forging step is performed at a temperature at which the zirconium alloy is in a state comprising crystalline phases A and B, for example, said forging temperature can be between 850 DEG C and 950 DEG C.

摘要： 본 발명은 수냉식 원자로의 스테인리스강 또는 다른 금속 구성 요소 표면 상의 균열의 성장을 완화시키는 방법에 관한 것이다. 예를 들어 팔라듐과 같은 귀금속을 함유하는 화합물이 상기 원자로의 물 속에 용액 또는 현탁액의 형태로 주입된다. 이 화합물은 원자로의 열 조건 하에서 분해되어 상기 귀금속의 이온/원자를 해리시켜 균열부의 내부 표면에 결합 또는 그 위에 적층시키는 성질을 가지고 있다. 상기 화합물은 유기적, 유기 금속적(예를 들어, 팔라듐 아세틸아세톤염) 또는 무기적 성질을 가질 수 있다. 균열부의 내부에 적층된 팔라듐은 대부분 표면의 팔라듐이고 유체 유동 조건 하에서 고갈되는 경우라도 촉매 성질을 나타내야 한다. 결과적으로, 균열부 내부의 전기 화학적 포텐셜은 입간 응력 부식 균열을 방지하는 임계 포텐셜 이하 수준으로 감소된다.
