Cold Climate Building Research at Wasa Base, Antarctica
During the Antarctic summer season of 1988-89 a permanent Swedish research station was erected at Dronning Maud Land, Antarctica. The station, named Wasa, is situated on a nunatak. A corresponding...
Minnesota Road Research Project - An Overview
The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research...
Spray and Ice Measurement Instrumentation for Ships
Bow slamming is the primary water delivery mechanism for ship superstructure icing. Spray flux is largely dependent upon hull dynamics, and cannot be computed numerically with current...
New Support for Pin-Hanger Bridges
To promote safety of their bridges, many state highway departments are considering ways to add auxiliary support to existing pin-hanger bridges. The Pennsylvania DOT and its open-end consultant...
Privatization Takes Flight
The number of air travelers in the U.S. is projected to double by early in the next century. Delays have also been mounting rapidly. Major airports around the world are facing the same...
Precipitator Retrofit and Repair: A Case Study
Described is a difficult fossil power station retrofit project performed on a tight schedule at a congested site. Installation of a new supplementary precipitator and structural repairs...
Anchoring?A New Generation
During the time period of NRC Bulletin 79-02, and certainly afterwards, the use and application of wedge type anchors in Nuclear Power Plants took on a new perspective. The data gathered...
Interim Spent-Fuel Storage Options at Commercial Nuclear Power Plants
Although spent fuel can be stored safely in waterfilled pools at reactor sites, some utilities may not possess sufficient space for life-of-plant storage capability. In-pool storage capability...
Properties and Environmental Impact of Stabilized Fly Ash
This paper summarizes the results of two research studies aimed at evaluating the properties and possible environmental effects of bituminous and lignite coal based fly ashes stabilized...
Stabilized Fly Ash Cover for a Municipal Waste Landfill
The study reported herein and several recently related projects have been aimed at reducing the hydraulic conductivity of fly ash and physiochemically fixing any potential leachable metals....
Environmental Aspects and Compliance Costs of Hydropower Regulation
Recent experiences by American Electric Power with respect to mitigation at hydroelectric project sites on the upper Ohio River indicate that compliance with environmental regulations...
Dam, Spillway and Hydropower Rehabilitation
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Current deficiencies include deterioration of original construction...
Hydro Rehabilitation?Innovative Solutions
Most hydro facilities have been in operation for many years and, consequently, must periodically have been rehabilitated. The high cost of energy, labor, materials, and financing dictate...
Fly Ash in Roller Compacted Concrete Pavement
This paper presents the state of practice on the use of fly ash in roller compacted concrete (RCC) pavements. Placed using asphalt pavers and compacted using asphalt rollers, RCC pavement...
Superplasticized High-Volume Fly Ash Structural Concrete
This research was carried out to develop structural grade concrete containing high-volumes of ASTM Class C fly ash. A Portland cement concrete, proportioned to have 28-day compressive...
