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...

Stress Distribution Around the Equipment Hatch Opening of a Prestressed Concrete Containment for a PWR Power Station
Results are reported of a finite element stress analysis for the linear elastic deformation around the equipment hatch opening in prestressed concrete containment. The dimensions and form...

A Case Study in Low-Level Radioactive Waste Storage
Capital funds have been appropriated for the design, engineering, and construction of an interim low-level radioactive waste storage facility. This project is currently in the preliminary...

Safety Investigations of Existing Spent Fuel Storage Structures for Increased Spent Fuel Storage Capacity
Delays in the solution of disposal problems continue to create the need for additional on-site spent fuel storage capacity at commercial nuclear power generating facilities. Rod consolidation...

Simplified Design of Flexible Expansion Anchored Plates for Nuclear Structures
The following two phases of the design of expansion anchored plates are discussed in this paper. a) Initial Design. b) Reassessment of as-built conditions. Initial design refers to the...

Evaluation of Non-Ductile Drilled-in Expansion Bolts
This paper provides background and justification for the design of closely spaced non-ductile drilled-in expansion bolts (bolts). It describes testing used to establish allowable design...

A Computer Integrated Engineering System for Nuclear Plant Design
The design, construction, and licensing of nuclear power facilities is a long and complicated process which can span a time period of over ten years. This tremendous lead time to plant...

An Estimate and Evaluation of Design Error Effects on Nuclear Power Plant Design Adequacy
An estimate by the author is found of typical error levels contained in Structural-Mechanical-Civil Design and Stress Reports. Based on the original analysis performed to demonstrate design...

Limit State Analysis of Lattice Steel Transmission Towers
The background and present status for limit state analysis of lattice steel towers at the Bonneville Power Administration is presented. Conceptual development, a computer program, and...

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...

Evaluating Data Collectors as a Surveying Tool
Data collectors play an increasingly important role in surveying. The data collector serves as an interface between the total station and the computer and as an electronic assistant to...

Database Management
Computer aided design systems have found widespread acceptance from Engineering companies as drafting/detailing/drawing tools. While this has brought a dramatic productivity improvement...

Automated Walking Cycle for Swinging Ladder Dredge
The unique application of a Swinging Ladder Dredge to perform maintenance dredging in the cooling canal system of the Turkey Point Power Plant demanded the design of a semi-automated dredge...

Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...

Numerical Modeling of Flow in Hydropower Intakes
To reduce high mortality of downstream migrating juvenile salmon at hydraulic turbines, traveling screens are used to guide the juveniles into a bypass channel for safe passage. However,...

Hydraulic Testing of a Large Make-Up Pipeline
A 37 mile pipeline which consists of sections of 114 inch, 96 inch and 66 inch pipes was constructed for delivering secondary sewage effluents for power plant makeup. During initial operations,...

Hydraulic Analysis of Water Transmission Flowing Party Full
The hydraulic behavior of a transmission line that flows full along only part of its length is more difficult to analyze than a completely full line. Unsteady open-channel and closed-conduit...

Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...

Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...

Valuable Design Insights Derived from Construction and Operation of Kinzua Dam
A number of design alternatives have surfaced during more than 17 years of operating experience at Kinzua Dam which should be useful in the design, construction, and operation of other...
