Plant Design Modification Engineering

ILD provides services for plant modification including design modification engineering analysis, design modification package development, and technical procedure writing.

Piping Analysis

ILD has piping stress and support analysis capabilities for performing ASME Section III Class 1, 2, and 3, ASME B31.1, and ASME B31.3 piping stress analyses. ILD capabilities include the ability to quickly and efficiently model and organize complex, multi-system piping, allowing for ease of analysis. ILD can model existing piping systems for depiction in 3D CAD software for ease of analysis.

Thermal/Hydraulic Analysis

ILD has been involved in system fluid transient analyses for more than 25 years. ILD has access to industry standard analytical tools to quickly and accurately evaluate, diagnose, and correct abnormal transient system behavior. Our experience includes line break mass energy release models, main steam turbine stop valve closure transient models, feedwater pump trip models, void collapse, and other scenarios.

Turbine Cycle Heat Balance

ILD is capable of developing turbine cycle heat balances to illustrate expected power cycle performance due to power uprate, component replacement, or degraded operating conditions.

Equipment Failure Evaluation (Root Cause Analysis)

ILD is able to quickly identify the cause of troublesome performance issues that may not be directly evident. Our experience allows us to understand the cause of degraded conditions and the proper procedure to mitigate further problems.

Operator Training and Operations Support

ILD maintains a training staff that includes certified SRO and RO training personnel, including previously licensed Senior Reactor and Reactor Operators.

ILD can also provide outage staff augmentation services, including:

• qualified operations outage co-ordination
• outage project management capabilities
• BWR fuel moving personnel
