The NRC issued this bulletin to accomplish the following: (1) Alert addressees to the importance of complying with existing regulatory guidelines associated with the control and handling of heavy loads at nuclear power plants while the plant is operating (in all modes other than cold shutdown, refueling, and defueled) and remind addressees of their responsibilities for ensuring that heavy load activities carried out under their license are performed safely and within the requirements specified under Title 10 of the Code of Federal Regulations. (2) Request that addressees review their plans and capabilities for handling heavy loads (e.g., spent fuel dry storage casks, reactor cavity biological shield blocks) in accordance with existing regulatory guidelines [specifically NUREG-0612 (Phase I) and Generic Letter (GL) 85-11] and within their licensing basis as previously analyzed in the final safety analysis report (FSAR). (3) Require addressees to report to the NRC whether and to what extent they have complied with the requested actions contained in this bulletin. Technical contact: Brian E.

MR Number: 3-96-0043 Dresden 2 Date: 04/12/96 Morris,Illinois N/A Dockets: 50-237 BWR/GE-3 Subject: REFEULING OUTAGE UPDATE AND PLANT RESTART Discussion: Unit 2 started its current refueling outage in June 1995. In November 1995 the licensee stopped work efforts on the Unit 2 outage and initiated a refueling outage "replan" effort to improve the planning, allocation and management of resources. On January 22, 1996, the Unit 2 refueling outage was restarted. At the time of this report, the licensee was in the final stages of completing all required prerequisites to enter into the STARTUP mode expected to occur the weekend of April 13. During the ten-month refueling outage a significant amount of work was accomplished. In addition to the normal refueling work, safety related material condition issues addressed included:  Overhaul of low pressure coolant injection and core spray motors.  Overhaul of high pressure coolant injection main, aux and booster pump.  Feedwater modifications to allow 3-element control.  Replaced all Scram Solenoid Pilot valve assemblies.  Reactor Water Cleanup Heat Exchanger and piping replacement.  Cleared Reactor Vessel Bottom Head Drain.  Implemented a Core Shroud repair.  Significantly reduced the number of operator work-arounds and control room deficiencies.  Modified structural steel in LPCI Heat Exchanger corner rooms. Regional Action: Following the outage restart in January 1996, inspections continued to focus on field activities with additional emphasis on the station's readiness for restart. In addition to inspecting specific work activities, a review of the licensee's engineering backlog identified several specific areas where the licensee had not fully justified deferring work past the outage restart. Most notable was a LPCI corner room steel modifications the licensee subsequently added to the outage work scope. The licensee reviewed other backlogs and found some additional examples of items that needed to be addressed prior to restart. Inspections of the resolutions indicated a strong licensee effort to assure the station's engineering backlogs did not contain any safety issue that was not adequately addressed prior to startup. Inspections in the area of configuration control identified weak implementation of "checklists" used for initial system lineups, and poor control of the station's "locked valve" program. For both of those issues the licensee completed extensive corrective actions which included a 100 percent reperformance of all 83 system lineup checklists. A number of UFSAR deviations were identified during routine inspections and by the licensee as part of their UFSAR "rebaseline" effort. All known significant deviations were resolved through the station's UFSAR change process, procedural revisions, or hardware changes. REGION III MORNING REPORT PAGE 3 APRIL 12, 1996 MR Number: 3-96-0043 (cont.) Inspections planned for restart include shiftly observations of control room activities and inspections of accessible areas of the plant as heatup progresses with particular emphasis on equipment and/or items worked during the outage. The resident inspection staff has been, and will continue to be augmented by specialist inspectors from the Regional offices (III and IV) and Headquarters technical staff.
