## Integrating Nuclear Safety 

**Into Design**

**Chip Lagdon,  Chief of Nuclear Safety**
**Jim McConnell,  Chief of Defense Nuclear Safety**

- Presented to OECM’s Project
- Director’s Workshop
- November 14, 2006

**Notes:**
“Better focus departmental awareness and management of issues related to nuclear safety.” Secretary Bodman, April 26, 2005. 
Prevent high-consequence nuclear accidents. 

## Authorities of the CTA

***Concurs with the determination of the applicability of DOE Directives involving nuclear safety included in contracts pursuant to DEAR 970.5204-2(b);***** **
***Concurs with nuclear safety requirements included in contracts pursuant to DEAR 970.5204-2(c); ***
***Concurs with all exemptions to nuclear safety requirements in contracts that were added to the contract pursuant to DEAR 970.5204-2;***** **
***Recommends to the Chief of HSS issues and proposed resolutions concerning DOE safety requirements, concurs in the adoption or revision of nuclear safety requirements (including supplemental requirements), and provides expectations and guidance for implementing nuclear safety requirements as necessary for use by DOE employees and contractors;***

## Authorities of the CTA

***Maintains operational awareness of the implementation of nuclear safety requirements and guidance, consistent with the principles of Integrated Safety Management across the DOE ESE/NNSA complex (including, for example, reviewing Documented Safety Analyses, Authorization Agreements and readiness reviews as necessary to evaluate the adequacy of safety controls and implementation);***** **
***Periodically reviews and assesses whether DOE ESE/NNSA is maintaining adequate numbers of technically competent personnel necessary to fulfill nuclear safety responsibilities; and,***
***Provides inputs to, reviews, and concurs with DOE-wide nuclear safety related research and development activities proposed by the Chief of Health, Safety and Security***

## Safety Integration into the Design Process

**“*****I expect safety to be fully integrated in the project.  Specifically, by the start of the preliminary design, I expect a hazard analysis of alternatives to be complete and the safety  requirements for the design to be established.  I expect both the project management and the safety directives to lead project on the right path so that safety issues are identified and addressed adequately early in the project design*****.” Deputy Secretary Clay Sell’s memorandum dated December 5, 2005**

## Safety Philosophy

**Safety controls must be conservatively established early in the design to avoid negative implications of having to modify design to accommodate additional controls or higher design pedigrees at later design phases**
**Safety controls can be refined or reduced with maturity of hazard/accident analyses in subsequent design phases**
**Potential “downgrading” of safety controls can be made through formal DOE review and approval and, if necessary, through the exemption process**

## EM Interim Guidance

**Interim guidance to EM acquisition projects (new and major modifications) on integrating safety early into the nuclear facility design in support of DOE O 413.3A implementation while DOE-STD-1189 is being developed**
**Released on July 18, 2006**
**Chief of Nuclear Safety endorsed the EM Interim Guidance**
**NNSA is reviewing EM interim guidance**
**DOE-STD-1189 is still being developed**

## Technical Guidance

**The Conceptual Safety Design Report (old PHA) at Critical Decision-1 should include initial scoping calculations of unmitigated radioactive and hazardous chemical releases and associated consequences to onsite workers and the public**** **
**For safety control determination for onsite workers, use 100 rem (TEDE) at 100 meter per DOE-STD-1120 and current site practices**** **
**For safety control determination for public protection, use criteria from DOE-STD-3009**

## Technical Guidance (continued)

**Dispersion modeling for dose calculation should use  conservative assumptions (95****th**** percentile meteorological data for both onsite workers and public, F Stability Class for atmospheric stability, and wind speed of 1.0 meter per second)**
**As hazard/accident analyses mature with the design, these modeling assumptions may be refined based on local site characteristics with sound technical justification**
**Use DOE published Toolbox Box safety analysis codes**
