    • Safety valves (100) accurately control closure and opening of fluid passage through the valve. Valves include a barrier (150) that blocks the fluid until removal only by a high-energy projectile (140). Following removal and opening, the barrier (150) or the projectile (140) can flow through the valve (100), which remains open. Bullets, pneumatic pistons, shot, coilgun pellets and any other forceful projectile (140) may impact and remove the barrier (150). The projectile (140) is actuated with any type of chemical reaction, firing pin, spring release, accelerating circuit, ignition circuit (141). Catchers (160) in the valve envelop or otherwise retain the projectile (140) or barrier pieces and enter the fluid flow of the opened valve (100) without blocking it. Disruptable barriers (150) include strong but breakable glass plates (250), thin steel sheets (350), a rotatable door (450) and other barriers that can withstand potentially over 10,000 psi (69 MPa) of fluid pressure while closing the valve (100). Valves (100) can use circuits (151) to both monitor valve open/closed status and initiate firing the projectile.
    • 安全阀(100)精确地控制通过阀的流体通道的关闭和打开。 阀包括屏障(150),其阻挡流体直到仅由高能射弹(140)去除。 在移除和打开之后,屏障(150)或射弹(140)可以流过保持打开的阀(100)。 子弹,气动活塞,弹丸,钢丝弹丸和任何其他强力射弹(140)可能会影响并移除屏障(150)。 射弹(140)以任何类型的化学反应,撞针,弹簧释放,加速电路,点火电路(141)致动。 阀中的捕集器(160)包封或以其他方式保持射弹(140)或阻挡件并且进入打开的阀(100)的流体流而不阻塞它。 可破裂的屏障(150)包括坚固但可破碎的玻璃板(250),薄钢板(350),可旋转的门(450)以及其他可以承受超过10,000 psi(69 MPa)流体压力的隔板,同时关闭阀门 100)。 阀(100)可以使用回路(151)来监测阀打开/关闭状态并开始发射射弹。

    • A nuclear reactor trip apparatus includes a remote circuit breaker trip device operatively connected to a reactor trip breaker to release a control rod into a nuclear reactor core, an active power source, a passive power source, and a local circuit breaker trip device operatively connected to the reactor trip breaker including a sensor to trigger the local circuit breaker trip device upon sensing a predefined condition. The active power source is electrically coupled to energize the remote circuit breaker trip device under normal operating conditions. The passive power source is electrically coupled to energize the remote circuit breaker trip device based on a loss of the active power source.
    • 核反应堆跳闸装置包括远程断路器跳闸装置,其可操作地连接到电抗器跳闸断路器以将控制杆释放到核反应堆堆芯中,有源电源,无源电源和本地断路器跳闸装置,其可操作地连接到 反应器跳闸断路器包括传感器以在感测到预定条件时触发本地断路器跳闸装置。 有源电源电耦合以在正常操作条件下激励远程断路器跳闸装置。 被动电源被电耦合以基于有功功率源的损失来激励远程断路器跳闸装置。
