TI 2515 193 HCVS and SAWM Inspection
It’s been seven years since the Fukushima Daiichi Nuclear Disaster. Since then, US Boiling Water Reactors (BWRs) have installed Hardened Containment Vent Systems (HCVS) and implemented Severe Accident Water Management (SAWM) strategies. The NRC will soon inspect licensee implementation using recently developed guidance in TI 2515/193. This inspection is a first-time evolution for both the licensee and the NRC.
Attributes of a Successful 2515/193 Inspection:
- Organization: Between, TI-2515/193, NEI 13-02 and EA-13-109, there are over 400 embedded requirements. A site needs to verify that each requirement has been met and correlate each requirement with an associated basis document.
- Preparation: Utilities have invested thousands of manhours in the design, installation and testing of the HCVS and SAWM strategies. The level of inspection preparation must be commensurate with the implementation effort.
- Responsiveness: Inspections are successful when licensees can provide timely resolutions to inspector questions. A site must ensure timely resolution of questions, when many of the project implementation staff have moved on to other positions.
- Benchmarking of Other Utilities: The sharing of information among sites is unique to the commercial nuclear industry. Often issues are identified and resolved as a result of peer-to-peer benchmarking and discussions. The assessment should have knowledge across multiple sites and incorporate best practices.
Our Focused TI 2515/193 Compliance Assessment
Building upon our experience with FLEX Compliance Assessments, XCEED Engineering, has expanded its offerings to include TI 2515/193 Compliance Assessments. XCEED’s proven compliance assessments have been completed as inspections preparation at multiple utilities across all NRC Regions. To-date, sites that completed an XCEED Compliance Assessment in preparation for NRC inspection activities have not received a single finding. Our compliance assessment process ensures a successful TI 2515/193 inspection:
- Organization: Our compliance matrix extracts each of the individual, embedded requirements into a Microsoft Access Database. Our Compliance Assessment correlates each extracted requirement with a documented basis for compliance. Through the database, the site is assured that all requirements have been met.
- Preparation: The XCEED Compliance Assessment covers all facets of the guidance documents. Our thorough assessment typically involves over 300 manhours and the review of over 200 documents. Resource-conscious utilities benefit from a rigorous, independent, objective assessment.
- Responsiveness: The database is a compilation of all requirements and associated compliance documentation. During an inspection, the database can be interrogated to resolve any inspection question. The database removes tribal knowledge requirement of inspection, and allows “green” staff to support the inspection
- Benchmarking of Other Utilities: XCEED has conducted FLEX assessments for multiple utilities and all NRC regions. Our staff compare site performance to other utilities and proactively suggest best practices.
