81 142 i _ i _ .. TP 370/1 - Heat Tracing - Functional Test The licensee representative stated that this test will be completed with TP 230/3, described above. These items will be reviewed on a routine inspection, when completed. (78-19-02) c. Tests to be Continued at Hicher Power Levels The licensee had completed the following tests at zero power or low power, but more tests are scheduled at higher power plateaus. TP 500/3 - Initial Radiochemistry Test TP 800/3 - Biological Shield Survey TP 800/35 - Effiuent and Effluent Monitoring System Test No problems were identified with these items. These items will be routinely reviewed as further tests are performed. (78-19-03) - d. Comoleted Tests The inspector reviewed the following test documents which the licensee has accepted as complete on the dates shown. SP 2 - Filter Efficiency Test (3/22/78) TP 171/2 - Control Building Ventilation Functional Test (& TCN-1) (1/17/78) TP 173/2 - Auxiliary Building Ventilation Functional Test (3/24/78) TP 230/1 - Radwaste Disposal, Miscellaneous Liquid - Functional ~~ Test (1/17/78) TP 230/2 - Radwaste Disposal, Reactor Coolant System - Func-tional Test (12/22/77) TP 231/3 - Radwaste Disposal, Gas - Functional Test (3/24/78) . a 81 143 l _ . . - .- . TP 232/1 - Radwaste Disposal, Solid - Functional Test (3/24/78) - TP 360/lC - RMS Test - Area Monitors (3/22/78) The inspector had no further questions on these items. e. Other Items The inspector observed the following conditions which will be examined again in a subsequent routine inspection to review their disposition. (78-19-04) (1) Unit 2 Secondary Chemistry Laboratory Fume Hood - face flow velocity The licensee representative stated that the exhaust blower needed maintenance, and the face flow velocity could not be checked on this inspection. (2) Decontamination Room - floor opening The inspector observed a (roughly 5" X 12") floor cpen-ing under the decontamination sinks. The ir.spector noted that any drips or spills could run through and contaminate the level below the decontamination rooin. (3) Decontamination Room Shower The inspector noted that some miscellaneous hardware would have to be moved to clear this shower space for use. The licensee representative stated that other showers were to be used instead for decontamination (see next item). (4) Other Shower Facilities (at Control Point) The inspector noted that no shower curtain or wall was installed and there was no threshhold to prevent water spreading across the floor into the control point. Nor-mal use of a shower appeared likely to splatter a hand and foot monitor and any personnel passing through the con-trol point. . 81 144 i l . - - - (5) Multi-Point Recorder Scale The licensee had ordered a dual scale to be installed . on a multi-point recorder. This recorder receives in-put from instruments requiring two different scales, only one of which was supplied. The disposition of these items will be reviewed on subse-quent routine inspections. 4. Respiratory Protection Program Part of the inspection effort was to verify that the respiratory protection program has been implemented with respect to Unit 2. Inspection indicated that the same program has been implemented in Unit 2 as in Unit 1. Personnel who have been qualified to wear respirators, where required to comply with 10 CFR 20.103(c), are identified on the records used to control their exposures. These individuals have a physician's approval to wear respirators and have been trained, fitted, and checked in a respirator test booth. No items of noncompliance were identified. 5. Radioactive Waste Systems Radioactivity levels had not reached those anticipated at full power operation. As described in paragraph 3.b, the reactor coolant evaporator for Unit 2 was not quite ready for use and the Unit 1 evaporator was processing coolant from both units, with no antici-pated problen. Three valves in the Unit 1 - Unit 2 liquid waste tie lines are being operated manually pending the installation of renote controls (WDL V 1169,1170, and 1171). The licuid waste system preoperational tests and the gaseous waste system preoperational tests were reviewed in paragraphs 3.c and 3.d. To the extent that the tests have been completed, the radioactive waste systems appeared to conform to the FSAR description and to the design bases given in the Technical Specifications. The identified inspector follow items (Paragraph 3) and the completion of the above controllers will be reviewed on a subsequent inspection. (78-19-05) .81-145 i l . - . _. 6. Ventilation Systems - Part of the inspection effcrt was to observe the operation and the upkeep of the ventilatio ' systems and to review the filter test results. The preoperational test at. eptance criteria for the in situ tests were 99.97% particulate fi' m' efficiency (DOP test) and 99.95% charcoal filter efficiency reon test). The filters were tested, .llowing any upkeep, between January and retested as necessar; ) 12 and March 9,1978. l /ollowing filters were tested. Control Building Ventilation Radwaste Disposal System Service Building Ventilation Auxiliary Building Ventilation Reactor Building Hydrogen Control System Reactor Building Purge System Revicw of the filter tests and observation of the upkeep of these systems did not identify any items of noncompliance. The inspector had no further questions on these items. 7. Exit Interview The inspector met with the licensee representatives (denoted in para-graph 1) at the conclusion of the inspection. The inspector reviewed the scope and findings of the inspection, t 81-146 , I .
