    • Monitor-guide-tube fixing sections are fixed to portions on a core support plate side of a plurality of in-core monitor guide tubes disposed in a reactor vessel. The monitor-guide-tube fixing sections are fixed to the core support plate disposed in the reactor vessel to fix the in-core monitor guide tubes to the core support plate. This makes it possible to realize improvement of rigidity of the fixed sections of the in-core monitor guide tubes. A tie plate is fixed to the in-core monitor guide tubes. The in-core monitor guide tubes are coupled by the tie plate. This makes it possible to realize improvement of rigidity of the entire in-core monitor guide tubes. As a result, it is possible to realize vibration damping for the in-core monitor guide tubes.

    • To provide a virtual tape device to reduce power consumption by utilizing a disk array device conforming to MAID. Two or more disk devices are divided into an information managing disk group whose power is kept on at all times and to two or more recording disk groups whose power is turned on/off as necessary when managing data. The virtual tape device includes: a volume information managing part which manages positions of virtual tapes allotted to storage areas of the recording disk groups; and a data managing part which rearranges, in the recording disk group whose power is on, the virtual tape for storing the data to the recording disk group whose power is off based on writing/reading information stored in the information managing disk group and positional information of the virtual tapes, and executes a control to write backup data to the recording disk group whose power is on.
    • 通过利用符合MAID的磁盘阵列设备来提供虚拟磁带设备以降低功耗。 两个或更多个磁盘设备被分成一直保持功率的信息管理磁盘组,并且在管理数据时,根据需要将其功率打开/关闭的两个或更多个记录磁盘组分配。 虚拟磁带装置包括:卷信息管理部,其管理分配给记录盘组的存储区域的虚拟磁带的位置; 以及数据管理部,其根据存储在信息管理盘组中的写入/读取信息,在存储在信息管理盘组中的写入/读取信息的情况下,重新排列在电源打开的记录盘组中,将用于存储数据的虚拟磁带重新排列到电源关闭的记录盘组上, 的虚拟磁带,并且执行控制以将备份数据写入到其打开电源的记录盘组。
