Outages & Emergent

Structural Integrity has dedicated response teams available to assist with emergent issues that arise during a plant outage.

Structural Integrity’s value helps power plant owners save time and money on issues that are difficult to solve and require the responsiveness and expertise that we uniquely provide. Examples of outage and emergent support include chemistry excursions to fuel failures, repair/replacement designs to third-party reviews, including modifications.

Flaw Evaluation/Operability

Structural Integrity is experienced in dealing with regulator reviews, and has a long track record of successfully defending our work to our clients’ benefit.

NDE data can be used to support engineering disposition of flaws according to ASME (American Society of Mechanical Engineers) Code, Section XI requirements, which can be used to support operability evaluations, justifications for continued operation, and relief requests, as required.

Flaw Characterization

Structural Integrity can quickly deploy situation-appropriate NDE technologies to site, including those that can be coupled with our new LATITUDE^TM non-mechanized, position-encoding technology, for accurate, initial characterization of flaws that are leaking or for confirmation of third-party examination results for suspected flaws.

With LATITUDE, we can rapidly confirm and characterize flaws. In some instances, we can also harvest field samples for detailed failure analysis at our Materials Science Center in Austin, Texas.

Repair/Replacement

Structural Integrity provides repair/replacement designs and supporting analyses commensurate with design requirements, as well as licensing documents and regulatory interface support when needed.

This support can be planned/long-term or be provided on an emergent basis when least anticipated or prepared. Structural Integrity’s 24/7/365 availability in these situations is a key and can be relied upon.

COMPONENT LIFE EXTENSION

VESSEL
INTEGRITY

The effects of radiation on vessel materials impact heatup/cooldown limits for PWRs, and increase hydrostatic test temperatures for BWRs, significantly limiting plant operation.

Structural Integrity manages reactor vessel integrity, with technical support including pressure-temperature curve development; reviews of RPV materials surveillance programs; setpoint evaluations; pressurized thermal shock evaluations; vessel fluence evaluations; and evaluations of projected vessel properties.

SERVICE
WATER

Service water systems, especially those that are safety related, are required to be redundant; they are subjected to a wide variety of operating conditions (e.g., intermittent flows, extended periods of stagnation) such that many systems spend most of their lives in wet lay-up that make water treatments difficult and corrosion problematic.

Structural Integrity is highly adept at characterizing and evaluating degradation and damage to justify continued operation until mitigative measures or planned repairs can be implemented.
