NOTICE OF VIOLATION Arizona Public Service Company Palo Verde Nuclear Generating Station Unit 1 Docket No.
50-528 License No.
NPF-41 EA 91-025 During an inspection aaiduzt~tl
'.on%ay 14 - June 24, 1988, violations of NRC requirements were identified.
In accordance with the "General Statement of Policy and,Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C
(1990), the violations a~ ~'"+"': '~:
A.
Technical Specification (TS) 3.1.3.6 provides that, when reactivity is greater than or equal to 1.0 (Mode 1 or 2, with the reactor critical) and reactor power is less, than 27K, regulating CEA group 3 shall not be at a
position lower than 60 inches withdrawn.
Technical Specification 3.0.4 states that entry into an operational mode
-" ~~
~a+ h~ m~6.
sonless the conditions of the Limiting Condition for ii,. wltI<.:>t rel.%ance en qmvisions contained in the action requirements of the applicable Technical Specification.
Contrary to the above, on Hay 14, 1988, the Palo Verde Unit 1 reactor entered Mode 2 and went critical with CA+ ~a~"1-.,'.:ing CEA group 3 lower than 60 inches withdrawn.
S.
Technical Specifica.',o.
G.H.I.
requires written procedures to be established and implemented to include the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February, 1978.
Appendix A, Item 2b, General Plant Operating Procedures, Plant Startup from Hot Standby to Minimum Load (Nuclear Startup), is implemented by procedure 410P-lZK3, Revision,7 reactor Startup.
Step 4.3.21 of 410P-lZZ03 requires the operator to "continue Regulating group withdrawal until the 'reactor is slightly supercritical, approximately
.2 DPM SUR j.decades per minute startup ratej."
Limitation and Precaution 3.6 of 410P-1ZZ03 requires that "criticality shall be anticipated any time CEA's are being withdrawn or boron dilution operations are being performed."
Contrary to the above, during the startup of Palo Verde Unit 1 on May 14, 1988, criticality was not adequately anticipated, and regulating group withdrawal was continued until a startup rate'f approximately-.7-DPH was reached.
C.
,Technical Specification 6.8.1.a requires that written procedures shall be established and implemented to include the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Reoulatory Guide 3 39, R~rrsCeri Z,, 4'p~..
.~ A, Section lh recottmends procedures covering log entries.
PVNGS"Procedure No. 40AC-9ZZ02 Revision 81, Sections 8.2 and 8.3, in part, implement the above require-ments.
Section 8.2 requires that a unit log be maintained by the on-shift Shift Supervisor and it is to include a broad overview of shift activities 9104160062 910408 PDR ABOCK 05000528 6
and
- c. a t:iia.al evant to safe, efficient oper ation.
Section 8.3 requires that a control room log shall document actions taken by the Control Room Operator that are significant or unusual.
Contrary to the above,'or the Nay 14, 1988 reactor startup, neither the unit log nor the control room log contained entries documenting reactor criticality or possible violation of the Power Dependent Insertion Limits, significant events which were also relevant to safe efficient operation.
D.
10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," requires 3icensees to establish measures to ensure that significant conditions adverse to quality are documented.
The ey".-~ved quality assurance program in FSAR Section 17.2 states that p j+erjon IF>
"Cnrrer~~>>o >f'tenn." is implemented by gA Procedure 03.02, QA T'rocedure D3.02 requires that "individuals identifying conditions
. adverse to quality shall document the condition... in accordance with the appropriate nonconformance procedure, e.g., work request, Operations NCR, EER, etc."
Contrary to the above, as of June 29, 1988, at Palo Verde Unit 1, an appropriate nonconformance report concerning an improper xenon decay constant in celcula..'".-
~'A-PV1-C02-87-54-00, "Response to EER-87-RX-019, U1C2 XE-OAP Tables amo Coefficients,"
a condition adverse to quality, had not been prepared.
This condition was identified prior to June 6, 1988.
These violations im the aggregate are categorized as a Severity Level III problem (Supplement I).
No <<esponse is required;
