Update on Impact Effects in Nuclear Plants Part III?Review of Heavy Object Drop
The consequences of an accidental drop of a heavy component from a lifting device in a nuclear power plant are required to be evaluated even though the device may have been designed using...
Computer-Aided Load Monitoring System for Nuclear Power Plant Steel Framing Structures
The design of nuclear power plant steel framing structures is a long and involved process. It is often complicated by numerous changes in design loads as a result of additions, deletions...
Reliability Assessment of Indian Point Unit 3 Containment Structure Under Combined Loads
In the current design criteria, the load combinations specified for design of concrete containment structures are in the deterministic format. However, by applying the probability-based...
A Study of the Correlation of the Components of Instructure Motions During Earthquakes
Thirty-two buildings are selected that have all three components of motion recorded in the basement, midheight and top of the structure. The correlation coefficients of these motions,...
Tension Tests of Containment Wall Isolated Liner Plates
Two tests were conducted using an approximate 2:1 ratio of hoop to meridional load. This simple load ratio is a gross approximation of the liner plate loading in a containment subjected...
Preliminary Analysis of Large Penetration Enclosures for Containment Vessels Subject to Beyond Design Basis Loadings
Numerical simulations of the macro-deformations of the sealing surfaces (gasketed junctures) of a PWR steel containment vessel's equipment hatch subjected to accident loadings...
Modeling Techniques for Seismic Analysis of Supported Systems
An automated seismic qualification process is presented which integrates the modeling and evaluation aspects of supported system design. Emphasis is placed on baseplate and joint design....
A Pseudo Response Spectrum Method for Mark I Loads
A pseudo base motion response spectrum method is developed to uniquely evaluate the periodic condensation oscillation and chugging drag loads that may occur on submerged structures within...
Development of Concrete Nuclear Containment (ACI 359) Code Requirements as they Relate to Probability Based Load
The historical development of the load combinations used in concrete containment is presented in the paper. These load combinations are examined and identified in the light of the reasonable,...
Containment Integrity of SEP Plants under Combined Loads
The containment designs analyzed consisted of three inverted light-bulb shaped drywells used in boiling water reactor (BWR) systems, and three steel-lines concrete containments and a spherical...
Bayesian Procedure for Evaluation of Containment Capability
The functional requirements of a steel or concrete containment is to maintain the structural integrity as well as the leak-tight integrity of its pressure boundary under specified design...
Structural Performance Predictions for Liner Plates on Nuclear Facilities
The history of the use of liner plates is presented. It is shown that the liner plate can be buckled, and can be bonded or not bonded to the concrete. The buckled plate usually has bending...
Santa Clara Valley Weather Modification Program
This report describes a significant advancement in the Santa Clara Valley Water District's knowledge and understanding of its weather modification (cloudseeding) program,...
Security of Unattended Pipeline Stations
The ultimate purpose of a security system is to maintain equipment and service in a normal operating condition or to restore the equipment and service to normal operating condition as...
Economics of Groundwater-Pumping Level Statutes
Pumping from one well may lower the water table in another to the point where pumping from it becomes unfeasible. Problems exist in allocating the increased costs of pumping caused by...
Ground Water Economics in the San Joaquin Valley
Ground water pumping in the San Joaquin Valley to supplement surface water supplies has increased from about 200 thousand acre-feet per year at the beginning of this century to nine million...
Drip Irrigated Cotton: Economics and Water Savings
Groundwater withdrawals for cotton production in the arid Southwest account for about 15 percent of all groundwater withdrawals. In Arizona, cotton's proportion of groundwater...
Computer-Automated Limit-States-Design of Steel Frameworks
The paper concerns the computer-automated synthesis of minimum-weight planar steel frameworks. For any number of applied loading cases, the design of the structure may be constrained by...
Reliability-Based LRFD for Transmission Structures
A simple reliability-based Load and Resistance Factor Design (LRFD) method is proposed for the structural design of electric transmission lines. With the proposed method, the designer...
Plastic Design Requirements of the AISC Proposed LRFD Specification
The American Institute of Steel Construction proposed LRFD Specification (1) has recently completed a one year period of trial use and review. This paper discusses the background of the...
