RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION REGARDING EXCESS FLOW CHECK VALVE SURVEILLANCE TEST FREQUENCY (TAC NO. MC4659)
This letter provides TVA's responses to the NRC request for additional information (Reference 1) regarding proposed Technical Specification (TS) 438.
On October 12, 2004 (Reference 2), TVA requested a TS change (TS 438) to revise the frequency of Surveillance Requirement 3.6.1.3.8 by testing a representative sample (approximately 20 percent) of Excess Flow Check Valves (EFCVs) every 24 months, so each EFCV is tested once every 120 months.
NRC requested additional information to support the review of the submittal.
The NRC requests and TVA's responses are enclosed.
TVA has determined that the additional information provided does not affect the no significant hazards considerations associated with the proposed amendment and TS changes.
The proposed amendment and TS changes still qualify for a categorical exclusion from environmental review pursuant to the provisions of 10 CFR 51.22(c) (9).

EXCESS FLOW CHECK VALVE (EFCV)
SURVEILLANCE TEST FREQUENCY NRC REQUEST
- 1.
"Page E1-7 under Section B, "EFCV Failure rate" states that TVA will address crud build up and valve sticking by flushing lines and inspection 100 percent of the EFCVs.
The application does not address the time period between performance of the testing and startup of the plant.
How will EFCV operability be maintained/assured during the time period between completion of the testing and startup of the plant?"
TVA RESPONSE All Unit 1 excess flow check valves will be inspected, cleaned, and tested prior to Unit 1 restart.
The testing will be accomplished during plant hydrostatic testing, which occurs just prior to restart.
The time period between hydrostatic testing and restart is currently scheduled for approximately four weeks.
This testing is sufficient to demonstrate operability until the next scheduled surveillance test.
NRC REQUEST
- 2.
"For EFCV refueling testing it is not clear what action the licensee will take if an EFCV failure is identified within the "representative sample" or if a repeat EFCV failure is noted.
For example, will another "representative sample" be tested?"
El-l
TVA RESPONSE At BFN, EFCVs are included within the scope of 10CFR50.65, Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants.
Technical Instruction 0-TI-346, Maintenance Rule, specifies no more than two EFCV failures are allowed over a 24 month rolling interval.
Investigations and evaluations would be performed in accordance with TVAN Standard Programs and Processes SPP 6.6, Maintenance Rule Performance Indicator Monitoring, Trending and Reporting.
Additional surveillances or corrective actions would be determined based on the evaluation of the specific failures.

- 1. INTRODUCTION The purpose of the CONAC code Is to evaluate the dose consequences of the four design basis accidents In accordance with NRC Regulatory Guides.. As originally written and described," the method of analysis required that containment and buliding parameters(i.e., leakrates, recircrates, purge rates, and filter efficiencies) remain constant during the entire accident tme. Unfortunately, as system modermg requirements became more demanding and buiding ventilation and purge system designs became more complex, It was necessary to evaluate the accident with variations In these parameters during the accident period. To make this analysis easier, the CONAC code was modified to allow modeling with such parameter changes.
.2.
DESCRIPTION The CONAC user models the plant as a system of compartments connected In serles.2 In the original version. the variables used to describe these compartments consisted of six arrays Indexed by compartment. These arrays have now been converted to two-dimensional arrays, indexed by compartment and time. An additional array and a new variable have been created to Identify the time periods. The new variable list for describing compartment behavior is as follows:
UTCHAN number of time Intervals TCHAN(IT) time at beginning of time interval IT; the first interval must always begin at time zero (hr)
RLEAK(ICMP,rr) leak rate from compartment ICMP to next compartmnent during time Interval IT (0%
per day)
FLEAK(ICMP,iT) leakage filter efficiency from compartment ICMP during Interval IT (%)
RECIRC(ICMP,1r) recirculatlon rate In compartment ICMP during Interval IT (V. per day)
FRECIR(ICMPrfl) recirculation filter efficiency for compartment ICMP during Interval IT (%)
purge rate to environment fromn compartment ICMP during Interval IT (% per day)
purge filter efficiency from compartment ICMP during Interval IT (0/%)
In addition to the above changes in Inputvalues, the outputtables were modified so the compartment variations with time can be printed In the output.
- 3. METHODS The only portion of the code which was changed was the section that calculates the Inventories and releases as a
,function of time. The sections which generate source terms, atmospheric diffusion factors (X/0) and doses were not modified.
In the originalversion.the compartment activityand release values were determined by calling the subroutine RELES, once for each Isotope. One call of RELES generated the values at all the times of Interest (typically 1 minute, 30 minutes, 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, etc;).

- oiticAccidednt Evauaton - The CONACO0 Code, March 1976 (NEDO-21 149).
See Reference 1, page 25 for an luatratkon.
NEDO-21 143-01 The modification consisted of reprogramming so that, for each time interval IT, RELES Is called once per isotope. The Inventories at the end of one interval became the Initial Inventories for the beginning of the nexd Interval. The program sorts through the times of interest and arranges them in the appropriate time intervals. For each interval, the values calculated at the times of Interest are then stored as the program moves on to the next Interval. Alter all the time Intervals have been processed, the tables of Inventories and releases at the t11es of interest are frnmed In the same format as the previous version of the code. Those tables are then used by the code to calculate the dose.
3.1 SAMPLE CASES Two sample cases are shown. The first (able 1) shows the Input only for running a case when parameters do not
- change with time. Note that NTCiiAN and TCHAN (1) default to the values of 1 and 0, respectively. Thus, they need not be Input for this case.
The second sample (Table 2) with output shows the method for a system that does vary with time.
- 4.
DESIGN VERIFICATION To assure that the code accurately calculates the desired values, several design verification runs were made.
- 1.
Run 2981 S -
This run compares the resuft of proviilng Identical Input to the old and new versions of CONAC or all four ccidents. The results were identical
- 2.
Run'2520S -
This run models the Black Fox LOCA. The Stack Fox containment has parameters that vary three imes. An analysis had previouslybeen performo and design verified for the Black Fox PSAR The previous analysis used the older version of CONAC. Each Uime Interval was run separately with output from the previous cases used to provide inputtothe next step. The results were summedby hand. The new version of CONAC dupicated the previous results.
- 3.
Run 2886S This run modeled the Phipps Send site. The parameters here changed five times. Results were compared with similar results obtained using the ORDOS code (unverilied code). These results agreed to two significant figures.
