- Denotes those attending the exit meeting on November 19, 1993. Containment local Leak Rate Testina-(61720) Purpose l The purpose of this inspection was to: ,
- Ascertain whether the licensee's containment local leak rate test (LLRT) program was being properly conducte * Independently verify the acceptability of the LLRT result Backaround Section 4.6.1.1 of the Palo Verde Nuclear Generating Station (PVNGS).- -t Units 1, 2, and 3 Technical Specifications (TS) requires that~ :
primary containment integrity shall be demonstrated periodicall *
To meet this commitment the licensee' established a LLRT program to-provide a means of testing to verify actual leakage rates of _
!
containment isolation valves and penetrations.- The purpose of the LLRT program was to provide a continually updated evaluation for-the
.
..
,
'
-
.
,
.
integrity of each unit's containment penetrations and of the containment as a whole. Unit I- was completing its fourth refueling outage (IR4) during this inspection. A Unit I containment ;
integrated leak rate test (CILRT) was initially scheduled to be performed during the IR4 outage,.but was cancelled prior to this inspection. As a result of lengthy past outages, the. licensee was -
preparing a submittal to revise Unit 1 TS to take advantage of the more flexible schedule allowed by Appendix J of 10 CFR Part 5 .
This proposed TS change would reschedule the Unit 1 CILRT to a future outage, c. LtRT Proaram The inspector sampled the licensee's containment LLRT. programs for Units 1, 2, and The requirements for local leak rate testing ^
were outlined in Nuclear Administrative and Technical Manual Procedures 73AC-9ZZ04, Rev. 09.05, " Surveillance Testing" and 73ST-ICL01, Rev. 4, " Containment Leakage Type 'B' and 'C' Testing." ,
Procedure 73ST-lCL01 defined the types of containment penetration testing as follows:
lype "A" Test - A test intended to measure the containment building overall integrated leakage rate; (1) after the containment building has been completed and is ready for operation and (2) at periodic intervals thereafte Tvoe "B" Test - A test intended to detect and measure local leakage across each pressure containing or leakage limiting boundary for the following containment building penetrations:
- Penetrations whose design incorporates resilient seals, .
r gaskets, or sealant compounds, expansion bellows or flexible :
metal seal ,
- Air lock door seals, including door operation mechanism penetrations which are part of the containment pressure boundar * Doors with resilient seals or gaskets (except seal welded). . As ,
'
an example, the containment equipment hatc Type "C" Test - A test intended to measure containment isolation valve (CIV) leakage rates. CIV's included were those that:
- Provide direct communication between inside and outside atmospheres of the containment building under normal operatio * Were required to close automatically upon receipt of a -
containment isolation signal intended to effect containment ,
isolatio ,
,
.'
-
i .,
,
- Were required to operate intermittently under post accident-condition d. Sample and Criteria The inspector selected the IR4 LLRT procedures and data for review during this inspection. A sample review of local leak rate summary '
test data from the last outages of Units 2 and 3 was also performe '
Procedures
,
The inspector reviewed the following licensee procedures:
- 73ST-ICL01, Rev. 4, " Containment Leakage Type "B" and "C" Testing" -
- 73ST-9CLO3, Rev. 04.01, "140' Containment Air lock Seal Leak Test"
Emergency Air lock Overall Leak Test and Interlock Test" ,
- 73ST-9CLO6, Rev. 3, " Containment Ventilation Purge Isolation Valve (42") - Penetration 56"
- 73ST-9CLO7, Rev. 3, " Containment Ventilation Purge Isolation Valves (8") - Penetration 78' and 79"
- 73ST-9CLO8, Rev. 00.01, "100'- Emergency Air lock Seal Leak
"
Test"
- 73ST-9CL10, Rev. O, " Containment Ventilation Purge Isolation Valves (42") - Penetration 57" l Test Data The inspector reviewed approximately 237 associated test data sheets .
completed for the IR4 outage, and surveillance test schedules to ensure: ,
- That all applicable containment penetrations boundaries (CPBs) and CIVs were local leak rate tested at the <
required TS frequency since the previous Type "A" ..
'
containment integrated. leak rate test (CILRT).
That the sum of the current local leak rates for all boundaries and valves subject to LLRTs met the acceptance criteri * That the licensee performed the actions required by the ,
TS, if the combination of the local leak rates was in j
.
'
-
.
.
excess of the acceptance criteri .
- The LLRTs were performed at containment integrated leak rate test (CILRT) peak pressure except where reduced pressure tests had received prior NRR approval in the T ,
- Penetration leakage rates were determined using the maximum pathway leakage. Maximum pathway leakage was defined in Inspection Procedure 6172 * Licensee criteria and response for LLRT and combined leakage rate failures were identifie * Licensee criteria and response for the leakage rate failures of components specifically cited in the TS were identifie .
Maintenance Reauest
>
The inspector reviewed lists of work orders issued for maintenance work performed on CPBs and CIVs since the last CILRT, for both the Unit I and the Unit 2 fourth refueling outages, along with six completed' work order packages for those outages. This review was performed to verify that the repairs and modifications performed on the penetrations were preceded and followed by LLRTs on the '
applicable penetrations. The tests for the following penetrations were verified:
Unit 1 (a) Penetration 28 - Safety Injection' Tank Drain (b) Penetration 40 - Regenerative Heat Exchanger ;
(c) Penetration 42A - Pressurizer Surge Sample (d) Penetration 43 - Reactor Coolant Pump Bleedoff (e) Penetration 50 - Refueling Cavity Drain Unit 2 (a) Penetration 09 - Radwaste Drain (b) Penetration 21 - Containment Spray

as required by the check valve progra No additional -
t actions were taken.
L The Part 21 report identified similar conditions that could result in a stuck open valve. The inspector l considered that the licensee actions in response to CRDR 1-3-0584 may have not-sufficiently taken into account the recommendation of the Part 21 report, including examination of the. valve internal Additional NRC review of the licensee's basis for this action is required. This concern is considered an unresolved ite i (Unresolved'50-528/93-49-01).
The inspector discussed this concern with the licensee on December 9, 199 .
The licensee stated they would review the Part 21 report and ;
their previous actions for this ite As-Left Leakaae The final the as-left maximum pathway leakage was identified by i the licensee as 29,918 plus or minus 808 SCCM on November 17, 199 ;
The inspector reviewed the performance of LLRTs to verify licensee actions were in accordance with the required action ;
of TS and licensee procedures. The inspector found that all Unit 1 CPBs and CIVs reviewed, except for the air lock inner-door equalizing valves discussed below, were tested using the acceptable inflow method. The testing reviewed was performed at'a containment integrated leak rate test (CILRT) peak pressure of approximately 51.5-52.0 pounds per square inch gauge (PSIG) except where reduced pressure tests had received prior NRR approval in the TS (e.g., air lock-door seals).
The inspector found that all penetrations listed in the TS were incorporated into the LLRT program. However the' inspector ,
noted that the inner door equalizing valves for both the'140'
containment air lock and the 100' emergency air lock (penetrations L1 and L3) in all three units,- were~ not being individually tested. The inboard door equalizing valves were:
clamped shut to prevent the valves from opening at the 51.5-52.0 PSIG test pressure applied to the entire air lock penetration. Due. to.the design of the equalizing valve it -
cannot be tested at pressure (from the air lock side) greater that the spring force which holds the valve closed.(i.e., -
approximately 10 to 15 PSIG), nor can it be readily tested in-the direction of flow from accident conditions. Therefore clamping was necessary. ' The test as performed only verified '.
that' one of the two o ring seals was sealing. The licensee stated that their existing method of ter+ing of the inner door equalizing valves sa',isfied the testin3 requirements of 10 CFR
.

-
.
Part 50, Appendix In discussions with the licensee, the inspector noted _that another Regi_on V licensee who had similarly clamped the inner door equalizing valves shut had interpreted that they were not testing their similar equalizing valves in accordance with the requirements of 10 CFR Part 50, Appendix J. That' licensee had taken the following actions:
- Classified their equalizing valve as subject to Type "B" testing requirements in that it was a part of the air lock mechanism (but not part of the door seal).
- Conservatively declared the inner containment air lock doors inoperable due to the untested equalizing valve * Elected to request an exemption to Appendix J, from the NRC, to test the equalizing valves by pressurizing between the valve seals at a reduced pressure (i.e., 5 to 10-
,
PSIG). This exemption was issued by the NRC on June 8, 1990, and those valves were tested satisfactorily. .
,
The inspector asked the licensee if they could identify if the-inner air lock door equalizing valves in all three units had a -
test port that would allow testing' between the' two o-ring seals installed in the valve disk. On' December 2, 1993, the licensee stated that the drawings for the six valves -(two per unit)
installed in all three units, showed that the valves contained ;
a test port. However the licensee had not been able to verify ,
that each valve actually contained a test port. The' licensee committed to take the following actions:
- Research maintenance and testing history on these valves :
to determine if there had been any identified valve leakage problem * Inspect available valves to verify the presence of a valve body seat test port. Unit 3 was shut down, however, the
'
valves in the other units may not be readily available for-inspection until the next scheduled containment entr The licensee stated that they would provide available information on the inner door equalizing valves to the inspector by approximately December 13, 199 On December 14, 1993, additional information on the LLRT of air lock inner door ,
equalizing valves was provided 'to the inspector. A December 10, 1993, memorandum ( No. 315-00397-TCC-WGW) identified that although the licensee maintained'the position that their current testing assured the ' operability of the equalizing :
valves in accordance with TS and their commitments to Appendix J, they planned to examine more rigorous testing of indiv_idual

The inspector noted that the current air lock testing had ,
verified the acceptable leakage of the air lock outer door and ,
its associated equalizing valve, for penetrations L1 and L3 in :

Oriainal NRC Violation NRC inspectors identified that the licensee had not included boric acid make-up pump discharge check valves CHN-V154 and CHN-V155 in their IST program. These valves were in the boron injection flow ,
path described in Technical Specification 3.1.2.2.c. This flow path was tested per procedure 41ST-ICH04,' Revision 2.03, " Boron Injection Flow Test 4.1.2.2.1.b". The flow path of this test utilized gravit feed from the refueling water tank through valve CHV-164 (boric acid filter bypass valve) and a charging pump to the reactor coolant system. However, the flow path was paralleled through ' check valves CHN-V154 and CHN-V155, and these valves were not individually teste Since these check valves were required to open, they were active check valves which required individual testing in accordance with Section XI of the ASME Boiler and Pressure Vessel Cod Licensee's Actions In Response To The Violation The licensee, in their December 31, 1992, response to the violation,-
