SUBJECT:

GENERIC ISSUE MANAGEMENT CONTROL SYSTEM REPORT FOR PERIOD ENDING JUNE 30,1999

)

in accordance with the FY-1999 RES Operating Plan, the update of the Generic issue Management Control System (GIMCS) is attached for your information. Since the last GIMCS report issued on May 4,1998, covered the status of the open generic issues as of December 1997, this report reflects all progress made in addressing open reactor and non-reactor generic issues between January 1,1998, and June 30,1999. The following is a summary of the activities that occurred during this reporting period:

(

i REACTOR GSis Two new generic safety issues (GSis) were identified and are scheduled for prioritization by the end of 1999 (see Table 5):

185 Control of Recriticality Following Small-Break LOCA in PWRs 186 Potential Risk and Consequences cf Heavy Load Drops in Nuclear Power Plants 1

One GSI was prioritized (see Table 7):

169 BWR MSIV Common Mode Failure Due to Loss of Accumulator Pressure (DROP).

Three GSis were reprioritized (see Table 7):

107 Main Transformer Failures (DROP) 1.F.2(1)

QA - Assure the Independence of the Organization Performing the Checking Function (LOW)

II.D.2 Research on Relief and Safety Valve Test Requirements (DROP)

Three GSIs were resolved with no new requirements (see Table 3):

165 Spring-Actuated Safety and Relief Valve Reliability (HlGH)

At the end of the reporting period, three GSIs remained to be prioritized (see Table 5), three GSis remained to be reprioritized (see Table 6), and twelve GSis remained to be resolved (see Table 1).

NON-REACTOR GSis Ten new GSis were identified and prioritized by NMSS (see Table 12):

7 Criticality Benchmarks Greater Than 5% Enrichment (LOW) 8 Year 2000 Computer Problem - Nonreactor Licensees (HIGH) 9 Amersham Radiography Source Cable Failures (HIGH) 10 Troxler Gauge Source Rod Weld Failures (MEDIUM) 11 Spent Fuel Dry Cask Weld Crack; (MEDIUM) 12 Inadequate Transportation Packaging Puncture Testing (MEDIUM) 13 Use of Different Dose Models to Demonstrate Compliance (MEDIUM) 14 Surety Estimates for Groundwater Restoration at In-Situ Leach Fields (MEDIUM) 15 Adequacy of Part 150 Criticality Requirements (MEDIUM) 16 Adequacy of 0.05 Weight Percent Limit in Part 40 (MEDIUM)

Five GSis were resolved with no new requirements:

6 Criticality Concems with Unusual Moderators in Low-Level Waste (MEDIUM) 9 Amersham Radiography Source Cable Failures (HIGH) 11 Spent Fuel Dry Cask Weld Cracks (MEDIUM) 12 Inadequate Transportation Packaging Puncture Testing (MEDIUM) l 13 Use of Different Dose Models to Demonstrate Compliance (MEDIUM)

At the end of the reporting period, six GSis remained to be resolved (see Table 15).

During the past year, increased attention was focused on the unresolved reactor GSis, as a result of the request by the U.S. Senate Subcommittee on Energy and Water Development for monthly status reports. This increased reporting frequency has placed a heavy reliance on GIMCS as a vehicle for collecting accurate, up-to-date summary information for use in i

preparing the reports to Congress. Therefore, in the future, GIMCS reports will be provided to f

you quarterly so that you can be kept abreast of the progress in completing the milestones that have been set for resolving the open reactor GSis.

I will continue to keep you informed of progress in resolving the remaining 24 unresolved reactor and non-reactor GSis as well as any major problems that might surface during the course of their resolution.
