PRIORITY ATTENTION REQUIRED MORNING REPORT - REGION I JANUARY 31, 1995 Licensee/Facility: Notification: Connecticut Yankee Atomic Power Co. MR Number: 1-95-0014 Haddam Neck 1 Date: 01/31/95 Hartford,Connecticut SRI E-Mail Dockets: 50-213 PWR/W-4-LP Subject: Inoperable Pressurizer Relief Valves Reportable Event Number: N/A Discussion: While shutting down for a refueling outage, plant personnel performed a routine surveillance test on the pressurizer power operated relief valves (PORVs) with the reactor operating in Mode 4 on January 29. Both valves (RC- 568 & 570) failed the test in that they would not operate to the full open position, and did not operate within the time required by the IST program. The PORVs are Copes-Vulcan model 080813 air operated valves. This was the third test failure of both valves in about two years. The licensee reported past failures as LER 94-05 (caused by excessive air leakage out of the air actuator due to improper assembly of the diaphragm/cover); and LER 93-07 (caused by inadequate sealing of the diaphragm assembly and corrosion failure of the regulator supplying air to the valves). At Haddam Neck, the PORVS do not perform the LTOP function (different valves are used), but the valves are required to be operable by Technical Specification 3.4.4 and are (i) designed to minimize the challenges to the pressurizer code safety valves for overpressure events; and (ii) credited for use in the EOP network as the feed and bleed path for loss of feedwater and steam generator tube rupture events. The licensee's preliminary investigation noted that both valves stroke smoothly and do not appear to have the excessive external leakage problems noted in past LERs. Licensee investigation is in progress and will continue during the performance of the pressure drop test for the PORV air supply header. Regional Action: Routine resident followup.

Region II contacted Nuclear Fuel Services (NFS) an NRC licensed fuel processor located in Erwin, Tennessee, and provided NFS the name and phone number of the citizen. NRC also contacted the State of Tennessee, which began direct coordination with the NFS representative. A health physics technician from NFS responded to the residence and performed a survey of the material. The material was found packaged in a paper towel inside two sealed plastic bags. On the front of the package the label "Uranium - I think" and on the reverse "from Arizona." Surveys performed by the licensee's health physics technician on the outside surface of the plastic bags indicated about 1.5 mr/hr (open window) and 0.02 mr/hr closed window. A spectrographic analysis of the material by NFS appears to confirm the material to be natural uranium ore. There was no detectable loose contamination present on the plastic bags or on any objects stored near the package. At the request of the resident, other objects and areas of the house were surveyed; no radiation or radioactivity was detected. The package, with the resident's permission, was removed from the house and is now at the NFS facility. A discussion with the resident appears to tie this package to an Arizona Uranium Mine Partnership of her deceased husband. This partnership existed about 1956. Above actions were coordinated with the State of Tennessee. Regional Action: None. Contact: Edward McAlpine (404)331-5547 Eldan Testa (404)331-6152
