|

|
| I in addition, several apparent violations were identified that are being considered for So escalated enforcement action in accordance with the " General Statement of Policy and Y Procedure for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600. As described below, the apparent violations involve the series of problems identified during

|
| On April 3,1997, your staff failed to effectively control diving activities in the Unit 2 spent fuel storage pool and as a result, a diver moved from a comprehensively surveyed area at the south end of the pool to unsurveyed areas at the north end of the pool. The diver sustained an unplanned exposure. Although no exposure in excess of regulatory limits is believed to have occurred, we are concerned that sufficient measures were not employed to provide positive contrnt of this activity which involved very high levels of radiation.

| | _ |
| | 10 CFR PART $0. APPENDIX B. CRITERION 16 Badgramm4 Near the end of the Unit 1 1994 Refbeling Outage (RTO), the block valve (1 MOVU O3 ) for PORY l ER%402 was discovered to be leaking. De leak was not expected since the velve had just been overhauled. We determined the luk rate, approximately eight gallons per hour, did not affect the valve's operability. An issue report was generated to invwtigate the leak during tlw 1996 RFO. |
|
| |
|
| Specifically, due to insufficient controls, including inadequate pre-job planning and communication, and lack of positive surveillance, the individual inadvertently came in close proximity to radiation fields in excess of 500 rads per hour.
| | The valve was disassembled and inspected during the 1996 RFO. Rubbing was found in the guide groove of the valve wedge. The rubbing was caused when the disk contacted a weld at the end of the valve's closing stroke. De contact caused the wedge to become cocked in the seat and resulted in the valveleaking. |
|
| |
|
| During the inspection period, we also noted a failure to control access to the Unit 2 containment, a high radiation area, via the emergency airlock, and a failure to properly document the problem in the corrective action system. Additionally, on May 1,1997, a worker performed maintenance for over one hour in a locked high radiation area inside the Unit 2 containment without any dosimetry. Subsequently, on May 4, two workers inadvertently gained access to a high radiation area during the construction of scaffolding in the Unit 2 auxilian :uilding. Although the last two problems occurred outside the inspection period, those issues, in conjunction with the loss of control of the diver, were considered to reflect an apparent breakdown in the applied radiation protection program, specifically the control of high radiation area access at Calvert Cliffs.
| | Valve Opwation and Test Equipment System (VOTT.S) testing at the start of the Unit 1 1996 RFO had shown an unexpected increase in disk pullout force. $1nce no unexpected increase in disk pull out force was seen in the other Unit I and 2 PORY block valves, the results of the VOTES tests supported our determination of the cause for the leak in 1 MOW 403. |
|
| |
|
| Accordingly, no Notice of Violation is presently being issued for these inspection findings.
| | To cornet the leak, the 1 MOW 403 wedge wu lapped, the wedge's guide grooves were enlarged, and excess base metal was removed. Enlarging the guide grooves and removing additional base metal were performed per the vendor technical manual. We failed to evaluate how changing the valve's internal A dirnensions would Impact the valve's operability. De "as.left" VOT1?S test did show that the disk pullout force was within expected values. |
|
| |
|
| In addition, please be advised that the number and characterization of apparent violations described in the enclosed inspection report may change as a result of further NRC review.
| | He System Engineer evaluated the valve repair. Ilowever, the evaluation was not ooordinated between the System Engineer and the Component Engineer. nc System Engineer evaluated the "as found" and |
| | "as-left" conditions of the valve. De System Engineer concluded the rubbing was limited to the seating portion of the stroke and did not affect the valve's ability to stroke shut. De Component Engineer was awwe that the valve had bwn repaired but only evaluated the "as found" and *as left" VOTES test results. De VOTES test ruults for the Unit I and 2 PORY block valves did not Indicate generic concerns. Neither the System Engineer nor the Component Engineer considered the full impact that machining the guide grooves might have on the valve's ability to function under design basis differential pressure conditions. A full evaluation would have considered the impact of changing the valve's internal dlmensions. |
|
| |
|
| A predecisional enforcement conference to discuss these apparent violations has been scheduled for June 12,1997 at 10:00 a.m. The decision to hold a predecisional enforcement conference does not mean that the NRC has determined that a violation has occurred or that enforcement action will be taken. This conference is being held to obtain information to enable the NRC to make an enforcement decision, such as a common understanding of the facts, root causes, missed opportunities to identify the apparent violation sooner, corrective actions, significance of the issues and the need for lasting and effective corrective action. In particular, we expect you to address the apparent lack of effective management oversight in both fuel handling and high radiation area access control, including the May 1 and May 4 high radiation area access problems, as well as the effectiveness of your corrective action processes in identifying and correcting problems in these areas, in addition, the conference is an opportunity for you to point out any errors in our inspection report and for you to provide any information concerning your perspectives on 1) the severity of the violations, 2) the application of the factors that the NRC considers when it determines the amount of a civil penalty that may be assessed in accordance with Section VI.B.2 of the Enforcement Policy, and 3) any other application of the Enforcement Policy to this case, including the exercise of discretion in accordance with Section Vll.
| | During May 1997, a Performanoe Prodletion Model(PPM) was run on I MOV 403 to verify the valve's satisfactory performance with its guide grooves enlarged. %c PPM determined that the valve in its curmut configuration would operate under design requirements. |
|

|
| You will be advised by separate correspondence of the results of our deliberations on these matters. No response regarding these apparent violations is required at this time.

De leak was not expected since the velve had just been overhauled. We determined the luk rate, approximately eight gallons per hour, did not affect the valve's operability. An issue report was generated to invwtigate the leak during tlw 1996 RFO.
The valve was disassembled and inspected during the 1996 RFO. Rubbing was found in the guide groove of the valve wedge. The rubbing was caused when the disk contacted a weld at the end of the valve's closing stroke. De contact caused the wedge to become cocked in the seat and resulted in the valveleaking.
Valve Opwation and Test Equipment System (VOTT.S) testing at the start of the Unit 1 1996 RFO had shown an unexpected increase in disk pullout force. $1nce no unexpected increase in disk pull out force was seen in the other Unit I and 2 PORY block valves, the results of the VOTES tests supported our determination of the cause for the leak in 1 MOW 403.
To cornet the leak, the 1 MOW 403 wedge wu lapped, the wedge's guide grooves were enlarged, and excess base metal was removed. Enlarging the guide grooves and removing additional base metal were performed per the vendor technical manual. We failed to evaluate how changing the valve's internal A dirnensions would Impact the valve's operability. De "as.left" VOT1?S test did show that the disk pullout force was within expected values.
He System Engineer evaluated the valve repair. Ilowever, the evaluation was not ooordinated between the System Engineer and the Component Engineer. nc System Engineer evaluated the "as found" and
"as-left" conditions of the valve. De System Engineer concluded the rubbing was limited to the seating portion of the stroke and did not affect the valve's ability to stroke shut. De Component Engineer was awwe that the valve had bwn repaired but only evaluated the "as found" and *as left" VOTES test results. De VOTES test ruults for the Unit I and 2 PORY block valves did not Indicate generic concerns. Neither the System Engineer nor the Component Engineer considered the full impact that machining the guide grooves might have on the valve's ability to function under design basis differential pressure conditions. A full evaluation would have considered the impact of changing the valve's internal dlmensions.
During May 1997, a Performanoe Prodletion Model(PPM) was run on I MOV 403 to verify the valve's satisfactory performance with its guide grooves enlarged. %c PPM determined that the valve in its curmut configuration would operate under design requirements.

O FA11NRE TO IMPIEMENT CORRECT!YE ACTIONS AS REQUIRED BY 10 CFR PART 50. APPENDIX D. CRITERION 16 From a review of maintenance orders of all the PORY block valves, we concluded:
A. He internal dbnensions of no other PORY block valyc had been changed; and B. Internal inspections, VOTES tests, and Motor Power Monitor tests show that one other PORV block valve had rubbing or interference. Cornetive maintenanoc was performed on that valve.
III. CORIIFMIVE STEPS W111Cll WII .T. IlE TAKEN To AY.DID FURTilER HO1AT10ES Training will be given to increase the knowledge level of selected site penonnel on MOVs:
A. Additional representatives from Engineering will attend PPM training.
D. Overview training will be given to ensure affected organizations understand the effects of maintenance and modifications on the operability of MOVs.
-
The controlling procedure for the MOV Program will be revised to require the MOV Component O Engineer to verify that perfortaanoe of MOVs is satisfactory and require an evaluation when valve internal dimensions which impact the design basis are changed.
IV. DATE WIIEN Full CSMPLIANCE WII.T. BE AcirfFVED ne PPM training is curnntly scheduled to be completed by Augu-t 1997.
The ovesview training will be completed prior to the 1998 RFO.
De controlling procedure for the MOV Program procedure will be revised by December 15,1997.
