Powers, RIV (817) 860-8195 PRIORITY ATTENTION REQUIRED MORNING REPORT - REGION IV JUNE 24, 1994 Licensee/Facility: Notification: Wolf Creek Nuclear Oper. Corp. MR Number: 4-94-0057 Wolf Creek 1 Date: 06/24/94 Burlington,Kansas Resident Inspector Dockets: 50-482 PWR/W-4-LP Subject: MARIJUANA AND PARAPHENALIA FOUND ON SITE Reportable Event Number: N/A Discussion: At 5:57 p.m. on June 23, 1994, during a routine search of a construction site, licensee security officers found a pipe which appeared to contain some marijuana lying on top of a stack of wallboard. The construction area is outside the licensee's protected area during the day, when construction activities are in progress, and becomes part of the protected area at night. The routine search was part of the process to move the security boundary to include the construction site within the protected area. Thus, the marijuana and paraphernalia remained outside the protected area. The licensee contacted management, the Resident Inspector, the construction company management, and the Coffey County Sheriff. The licensee requested the sheriff to perform a field test of the substance. The Sheriff's Deputy reported to the site and identified the pipe as typical marijuana paraphernalia available at any "head shop." A field test was not performed because Sheriff's Office budget constraints only permit a field test after a suspect is identified. The Sheriff's Deputy stated that the material appeared to be "high grade marijuana." The quantity of marijuana found was only that which was in the pipe in a volume approximately 1/8 inch in diameter and 2 inches long. The Sheriff's Deputy took possession of the material. No other material was found on the construction site. Regional Action: The resident inspector and Regional staff will monitor licensee actions.

MR Number: 4-94-0058 South Texas 2 Date: 06/24/94 Wadsworth,Texas Senior Resident Inspector Dockets: 50-499 PWR/W-4-LP Subject: REDUCTION IN POWER Reportable Event Number: N/A Discussion: On June 23, 1994, with Unit 2 operating at 100 percent power, licensed operators noted that the main turbine lubricating oil pressure had dropped to approximately 60 psig at the electrohydraulic control system interface valve. The interface valve is designed to open at 46 psig on decreasing oil pressure, dumping the electrohydraulic control hydraulic fluid, thereby actuating a main turbine-generator trip. The cause of the low oil pressure is assumed to be a failed open pressure relief valve or a malfunctioning regulator valve. Licensed operators began reducing reactor power at 1:25 p.m. on June 24. By 7 a.m. power had been reduced below the turbine trip/reactor trip permissive. The licensee intends to leave the unit operating at 45 percent power through the weekend while a turbine-generator outage plan is developed. Regional Action: Routine followup by resident inspectors.
