SUMMARY
OF THE DECEMBER 15, 2004 MEETING WITH NUCLEAR ENERGY INSTITUTE (NEI), ELECTRIC POWER RESEARCH INSTITUTE (EPRI) AND INDUSTRY REPRESENTATIVES ON REQUESTS FOR ADDITIONAL INFORMATION (RAIs) ON RISK MANAGEMENT TECHNICAL SPECIFICATIONS INITIATIVE 4b SUBMITTALS The NRC staff met with Industry representatives on December 15, 2004, from 9:00 a.m. to 5:00 p.m. The meeting attendees are listed in Enclosure 2.
The meeting consisted of discussions of: the Risk Management Technical Specifications (RMTS) Guidelines for RMTS Initiative 4b, Risk-Informed Completion Times (Enclosure 3), staff RAIs and industry responses (Enclosure 4) on the RMTS Guidelines; the staff RAIs and industry responses on South Texas Pilot (STP) RMTS Initiative 4b Pilot Proposal (Enclosure 5),
and the staff RAIs and industry responses on CE TSTF-424 RMTS Initiative 4b Pilot Proposal (Enclosure 6). An overview of the discussions is provided. In general, the RAI responses are good and the RMTS Guidelines are better. While significant progress was made, some work remains. A brief sense of the RAI discussion follows.
1.
PRA Quality and Configuration Risk Management Tools
- PRA Quality (scope, technical adequacy, level of detail) is not adequately defined.
The RMTS Guidelines state that it and RG 1.200 will address all PRA scope and capability requirements; minimum PRA attributes are not defined therein. The implication is that any level PRA is acceptable with a corresponding acceptable qualitative bounding assessment. The RMTS Guidance must explain that a plants ability to apply RMTS Initiative 4b must be commensurate with its PRA Quality.
- Licensee PRA Quality will need to be assessed for adequacy to implement the RMTS Initiative 4b process, including the adequacy of the PRA models to: calculate LERF increases, model degradation, model external events, and model various plant configurations.
- Licensee QA processes with respect to PRA maintenance and CRMP tools will need to be assessed.
- Uncertainties in the CRM tools and processes need to be evaluated and considered.
2.
Emergent Conditions
- The time to conduct risk assessments and account for potential common cause failures after an emergent condition is now proposed to be 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Worst case examples are to be provided to demonstrate that 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is appropriate; bounding for one additional TS inoperability.
- When within a TS action statement and its associated completion time (whether it is the front stop CT or a calculated RICT), subsequent risk assessments for emergent conditions shall be conducted with a purpose to confirm or establish an acceptable RICT. The RMTS Guidelines do not reflect this requirement.
- The industry intends to apply RMTS Initiative 4b to emergent plants conditions that will include complete loss of system function; Initiative 4b will subsume Initiative 6 on LCO 3.0.3 entry. The industry needs to address the nexus between Initiative 4b and Initiative 6.
3.
Examples
- The pilot plant and NRC staffs will meet to select a suitable set of plant configurations to apply the proposed Initiative 4b process, in order to appropriately evaluate the licensees PRA and Configuration Risk Management process.
4.
Documentation
- The documentation outlined in the CE response #47, along with some additional information such as ICDP, ILERP, and associated justifications (e.g., for compensatory measures), are appropriate for determining a RICT. This detail needs to be incorporated into the RMTS Guidance document.
5.
RMTS Guidelines
- RAIs on the updated RMTS Guidelines will be prepared by the staff and sent to the NEI RITSTF by the end of April 2005.
- An LCO exit strategy/shutdown must be addressed.
- The RMTS Guidance must be consistent with the processes described in the STP and CE pilot plant proposals.
- The RMTS Guidance must address: credit for contingency actions and compensatory measures, the treatment of potential common cause failures for emergent conditions, the acceptability of qualitative or bounding arguments used in the risk assessments; the tracking of accumulated risks, and the interface with NRC's reactor oversight program.
- The information and level of detail contained in the RMTS Guidelines will determine whether Initiative 4b will be a candidate for the Consolidated Line Item Improvement Process (CLIIP), and to a greater degree, whether exportable guidance will be provided to the follow-on plants to the pilot plants. The RMTS Guidelines needs to provide exportable guidance that is applicable, reliable and repeatable in other follow-on plants.
The NRC staff looks forward to receiving updated official responses to the RAIs, along with updated RMTS Guidelines and pilot plant proposals.
