  During a station blackout (SBO) accident reactor coolant pump (RCP) seals experience conditions that may cause seal degradation that can lead to a small loss of coolant accident (LOCA). The original models used in NUREG to quantify the likelihood and impact of a RCP seal LOCA were based on expert elicitation.   Seismic analysis of the primary system in nuclear plant design is very important. The change of reactor coolant pump has some impact on the support seismic loads of primary equipment. Using the numerical calculation method, preliminary analysis was completed and some valuable results are Author: Ye Xianhui, Cai Fengchun, Lan Bin, Zhang Yixiong.

  Westinghouse awarded a contract to Curtiss-Wright for four Generation II reactor coolant pumps and pump seals for the Tennessee Valley Authority deal. Those pumps will be built in : Kim Lyons. The reason for this last high risk is now recognized and is being corrected — this requires redesign of the reactor cooling water pump seal. For the two reactors where external events are included in the study, earthquakes add 40 chances per million for the BWR and 70 for the PWR, and fires add 20 for the BWR and 12 for the PWR.

The Reactor Coolant System (RCS) of a typical four loop MW(e) PWR consists of the reactor core within its pressure vessel, four coolant loops with pumps, the primary side of the steam generators and a pressuriser. In addition there are a number of auxiliary and safety systems which can interface with the RCS and these are discussed later.

The RCS Reactor Coolant Pump Seals book filled with high quality demineralised. @article{osti_, title = {Reliable reactor coolant pump seal performance - the station's role}, author = {Pothier, N E and Metcalfe, R}, abstractNote = {During the early days of the Canada deuterium uranium (CANDU) power reactor program, operators and designers learned that close attention to reactor coolant pump (RCP) seals was imperative for achieving high-capacity factors.

Westinghouse Electric Co. and project manufacturers are working to redesign a coolant pump for the plant. (Emphasis added.) The pump being redesigned is a reactor coolant pump manufactured by the EMD division of the Curtiss-Wright company.

There are four of these pumps in each Westinghouse AP® pressurized water reactor. Wetnhos ecn •~ Manal {eactor Coolant System General Description The RCS consists of several similar heat transfer loops connected in parallel to the reactor vessel (Figure ).

Reactor Coolant Pumps (RCPs) of various types are used to circulate the primary coolant through the reactor in most reactor designs. RCPs generally contain mechanical seals to limit the leakage of pressurized reactor coolant along the pump drive shaft into the containment. Subject: Impact of Reactor Coolant Pump No.

This seal has been rigorously developed and tested to provide up to a year life in order to reduce your seal maintenance cost, decrease refueling outage dose, eliminate seal installation issues, and.

The Reactor Coolant System pressure is trying to push the pump up, out of the system, while the pumping action of the impellor is trying to pull the pump down. Both the pump and motor have radial bearings, with the pump radial bearing being water lubricated, supplied from either the Seal Injection (SI) flow when available or Reactor Coolant.

When seal injection is lost, seal flow is supplied by reactor coolant leaking up along the pump shaft. Causes a loss of RCS inventory. Reactor coolant is not as clean as seal injection, potentially causing debris clogging the seals.

Reactor coolant is at higher temp (> °F) and must be cooled by the thermal barrier heat exchanger. Get this from a library. Determination of Westinghouse reactor coolant pump seal failure. [U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation,;].

Commission decision on the resolution of generic issue 23 " Reactor coolant pump seal failure.". The SmartSignal eCM system has been used to give early warning of seal degradation on a reactor coolant pump, by identifying a shift of 35 kPa in the first stage sealing pressure.

These seals are a different arrangement to most, and comprise three sections with water flowing through each in series, with coolers in between. This paper describes the results of a laboratory analysis performed on a reactor coolant pump (RCP) seal that experienced elevated leak-off temperatures after three months in service.

This article will explain what a mechanical seal is and the key design features that make them work. Basics of fluid pump sealing. A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.
