In accordance with 10 CFR 50, Appendix A, General Design Criteria 4, the Nuclear Management Company, LLC, (NMC) requests Nuclear Regulatory Commission (NRC) review and approval to exclude the dynamic effects associated with postulated pipe ruptures from the Kewaunee Nuclear Power Plant (KNPP) licensing basis. This request is for portions of the KNPP Residual Heat Removal (RHR), Accumulator Inje...

Ferric oxide, hematite, "red rust" , it has a lot of names but there is no argument that it is undesirable. It is a loosely adhering oxide layer which has poor heat transfer capabilities. It also tends to deposit elsewhere in the system. It can deposit in the coil, in steam traps and piping downstream, and can eventually reach the boiler. In the boiler it can form further deposits, which in tur...

—Piping Plovers (Charadrius melodus) are primarily monogamous birds that usually raise only one brood per season, but rare instances of double brooding have been documented. Piping Plovers breeding in the northern Great Plains, USA were studied in two locations: the Missouri River near the Gavins Point Dam (20052013) and the lower Platte River (2008-2013). There were 25 confirmed instances of d...

[1] This paper presents, for the first time, evidence to show that Calluna species are one causative factor of piping in blanket peat catchments. Ground-penetrating radar survey on 960 plots illustrated that piping was prevalent throughout blanket peats. However, soil pipe occurrence was significantly higher where bare peat (149 pipes/km) or Calluna (87 pipes/km) were present compared to other ...

Mechanical seals are the most common means of sealing industrial centrifugal pumps. There are a wide variety of seal options including the use of single or dual seal arrangements. While dual seals provide benefits in leakage containment and monitoring, single seals continue to be widely used due to their lower cost and simpler designs. Newer piping plans however offer options to increase leakag...

In this paper a new method of microwave nondestructive testing based on electromagnetic guided waves is applied to detect circumferential crack in the piping system of nuclear power plants. Microwaves as continues wave are generated by a network analyzer and amplitude of the reflection coefficient is measured by this network. For detection of any type of crack with any orientation in the pipe, ...

Quite often traditional specifications for temperature maintenance of sulfur piping and equipment call for the use of a steam jacket as a requirement for the proper handling of sulfur. This is usually based on historical practice which has not considered the availability of newer more economical methods such as the Thermon SnapTrace system which has also been proven to be an effective method fo...

We describe the implementation of a cellular-phone based speech translation system without telephone quality speech database or special CT hardware. The purpose is to quickly build a prototype service system that can be used for data collection with real users. To train the acoustic model for the speech recognition system, available high-quality databases were made usable by 1.) appropriate dow...

Abstract Piping systems are common in many architectures and designing such is often a complex task. Design automation of piping therefore universal research subject. Nonetheless, these still designed by hand as result their complexity. Consequently, costs associated with design high, especially for large-scale like ships chemical plants. The goal automatic pipe routing to reduce the time syste...

Birds frequently interact with people when they occur in coupled human-ecological or anthropogenic environments, which makes the protection of legally protected species a challenge. Flight initiation distances (FIDs) are often used to inform development of appropriate buffer distances required for human exclusion zones used to protect birds nesting in anthropogenic landscapes. Piping Plovers (C...
