Units 1 & 2 Docket Nos. 50-416 and 50-417 File 0260/L-334.0/L-350.0 Response to SER ltem 1.11(17)
AECM-82/153 Attached are responses or clarifications pertaining to issues discussed in either the Grand Gulf Nuclear Station Safety Evaluation Report (SER),
NUREG-0831, or the Final Safety Analysis Report (FSAR). The attachments address the final item pertaining to question 281.9 on post-accident sampling.
The attached procedure represents Mississippi Power and Light Company's final draft of the chemistry procedure for Estimation of Core Damage which was hased on the guidance provided by the Chemical Engineering Branch.
In addition, the last paragraph of NRC question 281.9 asked for documentation demonstrating the applicability of analytical procedures. At Grand Gulf, chemical parameters will be monitored by performing the grab sample analyses in the method as identified in the General Electric document NEDC-24889 entitled, " Post LOCA Sample Statistics-Compilation of Technical Information." It is our understanding, based on conversations with your Mr. F. Witt, that the analytical procedures identified in NEDC 24889 have been approved for use, therefore, no further documentation concerning the applicability of analytical procedures is deemed necessary.
If your generic review determines that the procedures and or nethods of l specific procedures are proven to be unacceptabic, please notify this office of your findings and the appropriate corrective actions will be made. As discussed with your Mr. F. Witt (CEB) and Mr. R. Phares of our staff on April 14, 1982, this concludes the information necessary to close the Grand Gulf Safety Evaluation Report, NUREG 0831, (SER) Iten 1.11(17) Post-accident sampling capability.
Should you have any questions or require additional information, please contact this office.

6.3 Cesium and Krypton, due to their longhalf lives, will be corrected by multiplyirg by the average capacity factor for the previ'ous three years.
6.4 l'easurements of Cs-137 and Kr-85 activitien may not be possible until the ,
i reactor has been shut down for several weeks to allow the decay of the shorter lived isotopes.
- 6.5 All values given are normalized to volumes of coolant at normal reactor
. coolant system pressure end temperature. To correct data, use At tachment II to determine factor X. -
- 6.6 The determination of percent failed fuel is biphly dependent on core
[ tenperature reached during the accident condition. Core tenperatures in excess of 1600*F indicate possible cladding damage. Temperatures in excess of 4000*F indicate possibl,e fuel nelt ing.
6.7 If the isotopic analyses show the absence of Ruthenium and Tellurium, then assume that fuel melting has not occurred . However, the presence of these nuclides does not necessarily confirm fuel melting.
6.8 Core damage below 1% is assumed to be a non-accident condition.

- b. If the hydrogen igniters have been energized, or there is evidence of a hydrogen burn, then the containment oxygen concentration must be obt ained from the Pos t Accident Sample Panel Oxygen Monitor (to be installed) or performed by grab sample analysis and entered in the calculations.
6.11 Iodine 131 6.11.1 Due to analysis of past reactor accidents, all released iodine is assumed to remain in the reactor coolant and/cr the suppression pool; therefore, the total iodine rele as ed is the summation of the two volumes and activities i f the suppression pool was used during the accident. ,
6.11.2 Iodine concentrations day increase by a factor of 2 to 25 times above the eauilibrium level due to spiking rollowing a large power change or shutdown.

Grand Gulf, the 100% Cesium activity nust be adjusted based on'a non-equilibrium maximum operational concentration. This adjustment assumes three years operation at 100% power.
6.12.3 Cesium test result s performed by on-line ins t rumentation or laboratory analysis will be entered on 4dtachawnf 1V. If the suppression pool was used as an extension of the reactor system, then test results of both systems should be included. Convert the measured act ivitiy to a total Cesium concentration released.
