Morning Report for March 8, 1999
Headquarters Daily Report MARCH 08, 1999 *************************************************************************** REPORT NEGATIVE NO INPUT ATTACHED INPUT RECEIVED RECEIVED HEADQUARTERS X REGION I X REGION II X REGION III X REGION IV X PRIORITY ATTENTION REQUIRED MORNING REPORT - HEADQUARTERS MARCH 8, 1999 Licensee/Facility: Notification: Part 21 Database MR Number: H-99-0024 Pyco Date: 03/08/99 Subject: Part 21 - Unqualified sensors fabricated into resistance temperature detector (RTD) assemblies Discussion: VENDOR: PYCO PT21 FILE NO: 99-13-0 DATE OF DOCUMENT: 02/25/99 ACCESSION NUMBER: SOURCE DOCUMENT: EN 35406 REVIEWER: PECB, V. Hodge NEW ISSUE. The vendor, PYCO, reports that a limited number of 200-ohm duplex resistance temperature detector (RTD) assemblies were fabricated by PYCO using thin-film sensors instead of wire-wound sensors specified for the assemblies. The vendor tested and qualified the wire-wound assemblies but not the thin-film assemblies. Both sensors have the same physical appearance and electrical characteristics and both sensors meet the requirements of the International Industrial Standard IEC-75 1, "Industrial Platinum Resistance Thermometer Sensors." The vendor supplied these thin-film assemblies to the licensees of the Robinson, Brunswick, and Summer nuclear power plants. The vendor notified these licensees. _ REGION III MORNING REPORT PAGE 2 MARCH 8, 1999 Licensee/Facility: Notification: Indiana MR Number: 3-99-0016 Michigan Electric Co. Date: 03/08/99 Cook 1 2 SRI via Telecon Bridgman,Michigan Dockets: 50-315,50-316 PWR/W-4-LP,PWR/W-4-LP Subject: D.C. COOK EXPANDED SYSTEM READINESS REVIEWS Discussion: On February 10, 1999, D.C. Cook Initiated an Expanded System Readiness Review (ESRR) initiative. The ESRR process consists of Safety System Functional Inspection type engineering evaluations, and system walkdowns to verify that key systems are capable of meeting their safety and accident mitigation functions. The systems that will be reviewed were divided into two categories, Level 1 and Level 2. The Level 1 systems were to be reviewed first and included Maintenance Rule risk significant systems and safe shutdown support systems including attendant/support systems. The Level 1 reviews include the evaluation of 56 systems. The scope of the less in-depth Level 2 reviews will include all remaining systems except the security systems. The ESRR process is expected to disclose design and licensing basis concerns. The licensee plans to complete the ESRR process by late May 1999, and a new integrated restart schedule will be published by June 1, 1999. The restart schedule will include the work scope needed to correct any deficiencies identified as a result of the ESRRs. The ESRR is currently in progress and issues are being identified regarding the ability of some systems to perform their design basis function. For example, on February 27, 1999, the licensee made a 10 CFR 50.72 notification (Event No. 35416) regarding potentially excessive thermal stress on two containment penetrations due to blocked cooling flow. The licensee expects that additional design issues will be identified as a result of the ESRR. Regional Action: Regional Inspectors are monitoring ESRR activities. Contact: A.

MR Number: 3-99-0017 Point Beach 2 Date: 03/08/99 Two Rivers,Wisconsin Resident Inspector Observation Dockets: 50-301 PWR/W-2-LP Subject: UNIT 2 REACTOR STARTUP Discussion: The Point Beach Nuclear Plant Unit 2 was placed online at 1:33 a.m. on March 7, 1999, ending the 23rd refueling outage. The reactor had been made critical on February 26, 1999. The outage, which began on December 4, 1998, included reactor vessel baffle former bolt inspections, loading of the Unit's first 18-month fuel core, and retrofit of the two low pressure turbine rotors. The Unit is scheduled to remain online until the fall of 2000. Regional Action: None Contact: R.D. Lanksbury (630)829-9631 _
