When using the Right-Hand Rules, it is important to remember that the rules assume charges move in a conventional current (the hypthetical flow of positive charges). In order to apply either Right-Hand Rule to a moving negative charge, the velocity (v) of that charge must be reversed--to represent the analogous conventional current.

2018年8月8日 · The direction your fingers curl represents the direction of the magnetic field. So, when you use this rule, you'd see that no matter what part of the loop you use the right hand rule on, your fingers will be pointing towards you to the left of the current, which tells you the answer should be out of the page.

similar heat transfer loops connected in parallel to the reactor vessel. Each loop contains a steam generator, a reactor coolant pump, penetrations for connection with auxiliary and emergency systems, and appropriate instrumentation. In addition, a pressurizer is connected by a surge line to one loop for pressure control. A

the condenser. The shutdown cooling mode of the residual heat removal (RHR) system is used to complete the cooldown process when pressure decreases to approximately 50 psig. Water is pumped from the reactor recirculation loop through a heat exch anger and back to the reactor via the recirculation loop.

2017年1月11日 · The residual heat removal system (RHR) is a low-pressure loop in parallel with the reactor coolant system. During the cold shutdown of reactor, the residual heat removal system is put into operation in order to remove the heat of the reactor and reactor coolant system (RCS) when the pressure and the temperature of the primary coolant drop to 2. ...

2021年3月9日 · As an interim corrective action, the licensee modified its operating procedures to allow only one loop of RHR at a time to be operated in the suppression pool cooling mode of operation. In addition, the licensee planned to revise plant procedures to address restart of an RHR pump if it trips while operating in the suppression pool cooling mode.

During mid-loop operation, vortexing at the junction of the RHR system suction line and the hot leg can occur and the air entrained into the RHR pump suction line can degrade or interrupt pump performance. Consequently, it may cause an event of the loss of RHR resulting in the core uncovery and severe core damage [1].

余热排出系统 (RHR)的主要功能是在电厂停堆期间，在经蒸汽发生器初步冷却和降压后，从堆芯和反应堆冷却剂系统 (RCS排出热量，将反应堆冷却剂温度降至冷停堆值;维持RCS的冷停堆温度;维持冷却剂通过堆芯的强制循环。 免责声明：本网转载自合作媒体、机构或其他网站的信息，登载此文出于传递更多信息之目的，并不意味着赞同其观点或证实其内容的真实性。 本网所有信息仅供参考，不做交易和服务的根据。 本网内容如有侵权或其它问题请及时告之，本网将及时修改或删 …

2023年6月12日 · The answer provided for this question: From the RHR for loops, place the heel of the right hand in the plane of the loop so that the fingers are curled in the direction of the current. The extended thumb points in the direction of the B-field. Since it is anti-parallel to the external B-field, the loop will flip over and then remain at rest.

Both the direction and the magnitude of the magnetic field produced by a current-carrying loop are complex. RHR-2 can be used to give the direction of the field near the loop, but mapping with compasses and the rules about field lines given in Chapter 22.3 Magnetic Fields and Magnetic Field Lines are needed for more detail
