e ENCLOSURE 1
NOTICE OF VIOLATION Arizona Public Service Company Docket Nos.:
50-529 Palo Verde Nuclear Generating Station 50-530 License Nos.:
NPF-51 NPF-74 During an NRC inspection conducted on April 21 through 0une 1,
- 1996, two violations of NRC requirements were identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
NUREG-1600, the violations are listed below:
A.
Technical Specification 6.8. 1 requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Regulatory Guide 1,33, Appendix A, Revision 2, requires, in part, written procedures for procedural adherence.
Procedure 01OP-OAPOI, "Procedure Process,"
Revision 1, Step 6.2,
- requires, in part, that procedure users are responsible for adhering to the requirements of the procedure.
Contrary to the above, the inspectors identified two examples where licensee personnel, on different occasions, failed to adhere to the requirements of the procedure as evidenced by the following:
1.
Procedure 40AL-9RK28, "Panel 8028 Alarm Responses,"
Revision 26, Window Number 28098, page 3 of 12, Step 3, prescribes, in part, that if the indicated pressure on SIN-PI-319 is greater than 1540 psig, then declare low pressure safety injection (LPSI) 8 inoperable; and page 7 of 12, Step 3, prescribes, in part, that if the indicated pressure on SIN-PI-339 is greater than 1540 psig, then declare LPSI A inoperable.
On April 30,
- 1996, in Unit 2, when pressure on SIN-PI-319 exceeded 1540 psig, operators failed to declare LPSI 8 inoperable, and when pressure on SIN-PI-339 exceeded 1540 psig, operators failed to declare LPSI A inoperable.
As a result, both trains of LPSI were inoperable for approximately 15 minutes, 2.
Procedure 420P-2SG03, "Operating the Steam Generator (SG)
Blowdown System,"
Revision 21, Section 6.3, "Performing High Rate Blowdown on SG 1 to the Hain Condenser,"
provides instructions for realigning the blowdown system to the blowdown flash tank.
On Hay 11,
- 1996, in Unit 2, the procedure was not used by an operator when realigning the blowdown system, and the system was left isolated.
As a result, actual reactor power was slightly greater than indicated power and exceeded the licensed thermal limit by a
small amount.
This is a Severity Level IV violation (Supplement I) applicable to Unit 2

Technical Specification 6.8. 1 requires, in part, that written procedures
'hall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Regulatory Guide 1.33, Appendix A, Revision 2, requires, in part, written radiation protection procedures for contamination control.
Procedure 75RP-ORP01, "Radiological Posting," Revision 13, Step 3.4. 1,
- requires, in part, that areas identified as having contamination levels greater than 1000 disintegrations per minute per 100 square centimeters shall be posted with radiological warning sign(s) bearing the words "caution, contaminated area."
Contrary to the above, the inspectors identified three areas as having contamination levels greater than 1000 disintegrations per minute per 100 square centimeters that were not posted with radiological warning signs bearing the words "caution, contamination area."
The examples were the following:
~
On May 9, 1996, the floor under Unit 2 valve SIA-UV-655 had contamination levels as high as 15,000 disintegrations per minute per 100 square centimeters.
~
On May 9, 1996, the floor under Unit 2 drain valve SIB-V555 had contamination levels as high as 70,000 disintegrations per minute per 100 square centimeters.
In addition, the pipe cap downstream of valve SIB-V555 had contamination levels as high as 30,000 disintegrations per minute per 100 square centimeters.
~
On May 16,
- 1996, the floor under Unit 1 valve SIA-UV-655 had contamination levels as high as 40,000 disintegrations per minute per 100 square centimeters.
This is a Severity Level IV violation (Supplement IV) applicable to Units 1 and 2.
Pursuant to the provisions of 10 CFR 2.201, Arizona Public Service Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN:

- 76011, and a copy to the NRC Resident Inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice).
This reply should be clearly marked as a "Reply to a Notice of Violation" and should include for each violation:
(1) the reason for the violation, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results
- achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full
