Balance of Plant (BOP) Evaluations

ILD has extensive experience with the operation, performance and maintenance of all BOP components as well as an understanding of how individual components may affect the entire thermal performance cycle. ILD has the necessary expertise to identify, diagnose and correct many abnormal plant operating conditions. Analysis examples include:

Equipment Out-of-Service

Using an analysis technique based on the same principles as heat balance development, ILD can provide Equipment Out of Service Evaluations including MSR OOS and Feedwater Heater OOS evaluations. Removing a heater from service can impact other equipment including the main turbine, system pumps and the remaining in service heaters. For this reason, ILD has developed a simplified method to determine the impact on other plant equipment, and in turn, determine the reduced operating thermal power level required to avoid equipment damage while maintaining unit output.

Heat Balance Development

ILD can develop a cycle heat balance diagram based on actual plant operating data to show how your cycle is performing compared to baseline vendor performance predictions. This type of “as-built” diagram is particulary helpful when planning for modifications such as power uprate and/or main turbine rotor replacements.

Heat Exchanger Tube Vibration Analysis

ILD is one of the few companies that can perform the complex Connors Fluid-elastic analysis for heat exchanger bundles to determine if your equipment is susceptible to flow induced vibration. ILD has incorporated industry standard analytical techniques in standard calculation methods to simplify this analysis.

On-line Condenser/Cooling Tower Model

The ILD Condenser and Cooling Tower Model was developed by ILD more than 20 years ago and continuously improved. The model is tailored to your plant’s specific condenser and cooling tower configuration. It can be used to predict the MW effect of varying parameters such as weather conditions, inlet water temperature, circulating water flow and tube plugging.

Steam Jet Air Ejector Performance Assessment and Improvement

Degraded Steam Jet Air Ejector (SJAE) performance can cause undue loss of power generation. It is therefore important to quickly analyze the system and take action to correct any issues. ILD has experience and analytical tools necessary to trouble-shoot the SJAE system from the condensers to the hydrogen recombiners.
