personnel agreed with the inspectors comment and plan to-clarify the procedur This same procedure was recently revised to satisfy NRC concerns' expressed in NRC Inspection Report 50-302/88-2 Apparently the licensee's ef forts .to improve procedure PM-112 were unsuccessfu l Inspector Followup Item (302/89-08-01): Review the clarifications to procedure PM-11 (10) Radioactive Waste. Controls (71707) - Selected liquid releases

.and solid waste compacting were observed to verify that approved procedures were utilized, that appropriate. release approvals were obtained, and that required surveys were take No violations or deviations were identifie . Review of Nonconforming Operations Reports (71707)

The inspectors reviewed Nonconforming Operations Reports (NCORs) to verify the following: TS are complied with, corrective actions as identified in the' reports or during subsequent reviews have been accomplished or are being pursued for completion, generic items are identified and reported as required by 10 CFR Part 21, and items are reported as required by T All NCORs were reviewed in accordance with the current NRC Enforcement Polic NCOR 89-62 reported that a visual inspection of the "A" Reactor Coolant Pump (RCP-1A) motor found deficiencies. The licensee's

, inspection of the motor revealed that the rotor cage had shifted and was resting against the rotor fan. In addition, during the removal l

and inspection of the rotor a few drive end space blocks were found

! loose and had tilted slightly. An inspection of RCP-1B and RCP-1C motors revealed similar deficiencies. An inspection of RCP-10 motor showeo only that the rotor cage had shifted and was resting against i the rotor fa An analysis of these problems was performed by the vendor (General Electric Canada Inc.). The shift of the rotor was considered to be a minor problem which could result in contact between the motor's rotor cage shorting ring and the rotor f an which could result in arching during a motor star The vendor recommended this condition be repaired when convenien The loose space blocks are considered to

be a more serious problem and could result in stator damage and a motor trip if the space blocks become dislodge The vendor recommended this condition be repaired prior to starting the pump The licensee has subsequently repaired the motors for RCP-1A, RCP-1B and RCP-1C and plans to repair RCP-10 during the next refueling outage presently scheduled for Mxrch 199 Inspector Followup Item (302/89-08-02): . Review the licensee's activities to repair the motor for RCP-I b. NCOR 89-65 reported that during an inspection and repair of the "B" Nuclear Services Seawater Pump (RWP-28) excessive corrosion was noted on.the pump's tube tension adaptor. The failure of this part could cause excessive pump vibration and subsequent pump failure. This pump has been in service for approximately 15 years. The licensee-has subsequently replaced the defective parts and has discussed this problem with the pump's manufacturer (Bingham Willamette) who recommended that the other seawater pumps be inspected for similar damage. The licensee plans to inspect the other pumps (RWP-3A and RWP-38) during the next refueling outage. The pump manufacturer concurred that.the pumps could be operated without problems for this interva Inspector Followup Item (302/89-08-03): Follow the licensee's activities to inspect and repair RWP-3A/3B for corrosion damag c. NCOR 89-77 reported that the trip setpoint associated with radiation monitor RMA-2, Auxiliary Building (AB) and Fuel Handling Area Exhaust Duct Ponitor, was found above the limit required by TS 3.3.3.9. This condition was identified by the licensee on April 13, 1989 during the generation of a routine weekly AB release permit. The monitor's trip setpoint was found to be off scale high (greater than 1,000,000 counts per minute (CPM)) whereas the required setpoint was approximately 5,200 CPM. The licensee's preliminary investigation revealed that this condition had probably existed since approximately April 8 when the monitor was calibrated. The higher trip setpoint

, would not have alerted operators to a potential release in excess of the radiation limits allowed at the site boundar The licensee has experienced previous problems with establit,hing correct radiation monitor trip setpoint On March 25, 1988 the licensee reported (LER 88-10) that the trip setpoint for radiation monitor RMA-2 was set too high. The licensee attributed the cause for this event to be a deficient procedure and implemented corrective action to revise the procedure. This event was discussed in NRC Inspection Report 50-302/88-14 and was considered by the NRC to be.'a Licensee Identified Violation (LIV 88-05). In September, 1988 o effluent monitor setpoints for a liquid release were round to be set l improperly. The licensee attributed the causes for this event to be personnel error and a lack of procedural guidance. The licensee's

corrective action for- this event included revising the specific procedure to provide more guidance. This event was discussed in NRC l Inspection Report 50-302/88-29 and was considered to be a LIV (LIV 88-10).

Althot.gh the licenset nas taken corrective action for each of the specific events discussed above, this corrective action was insufficient to encompass the general overall. problem of deficien procedures for establishing correct radiation monitor trip setpoints and resulted in another recurrence of the nonconformance on April 1 Failure to take sufficient corrective action to prevent recurrence of a nonconformance is contrary to the requirements of 10 CFR Part 50 Appendix B, Criterion XVI and is considered to be a violatio Violation (302/89-08-04); Failure to take adequate corrective action to establish correct radiation monitor trip setpoint . Installation and Testing of Modifications (37828)

Installation of new or modified systems were reviewed te verify that the changes were reviewed and approved in accordance with 10 CFR 50.59, that the changes were performed in accordance with technically adequate and approved procedures, that subsequent testing and test results met acceptance criteria or deviations were resolved in an acceptable manner, and that appropriate drawings and facility procedures were revised as necessary. This review included selected observations of modifications and/or testing in progres During a review of modification package MAR 87-01-19-01, Reactor Building Depressurization, the inspector noticed that an attachment to the modification safety evaluation included proposed revisions needed to the Technical Specifications and the Final Safety Analysis Report (FSAR).

This modification changed the engineered safeguards Reactor Building (RB)

isolation close signals from the RB purge 48 inch butterfly valves (AHV-1A/1B/1C/1D) to 6 inch hydrogen vent valves (LRV-70/71/72/73). The smaller vent line is to be used to allow RB depressurizction during operating modes 1 through 4 when the RB purge valves are locked in the

, closed position. Upon reviewing the proposed FSAR change, the inspector noted that the description of the RB depressurization system was not included. A review of FSAR Section 5.5, Reactor Building Venti 11ation a% Purge Systems, revealed that the hydrogen vent system was also not deu ribed.. Further, the inspector noted that the RB vent 111ation and ext.au>t flowrates assumed while the reactor is operating in paragraph 5.5.1.2.d would be deminished by the use of the smaller depressurization system, yet no proposed change for this paragraph was include These matters were discussed with licensee personnel. Although the proposed FSAR. revision had not yet been reviewed and approved for submittal to the NRC, licensee personnel agreed that clarifications needed to be made to the FSAR to adequately describe the RB ventilation syste . _ _ _ _ _ - _ _ _ _ _ _ _ - _ - _ _ _ _ _ _ - _ _ -
