Dear l'r. Curtis:
Ul!JECT:
TYI TASK ACTION ITEM I.G.l SPECIAL LOl.'Gl'ER TL'ST PFOGPN'.
FO..
Bl"PS By letter dated October 31, 1980, we sent ou a copy of YUPEG-0737, "Clarification of TMI hctfcn Plan Acquirer.erts."
Enclosure 2 cf NUPFO-0737 constitutes a ccmpilation cf those items that have been specifically approved by the Commission for frrplementatfon as operating license requirements.
The purpose of this letter is to prnvirfe additional guidance vjith regard to TMI Task Action Plan I.G.l as it applies tc O'L'R OL applications.
The basic require-ments for a special low power test program vere provided in NUREC-0694 (referenced as being issued 6/26/80 in Enclosure 2 to NUREG-0737).
NUPEG-0694 requires applicants to "deffne and cornrft tc a special low power testing pronram approved hy I'RC to be conducted at power levels no greater than 5 percent for the purposes of providing meaningful technical information beyond that obtained in the normal startup test program and to provide supplemental training".
A low peter test pror rarr. similar to the one developed by TVA for Sequoyah and and ccnsisting of demonstraticns of sfr ulated decay heat removal under degraded plant conditions has been approved for Pl"R applicants.
The "degraded conditions" tn which PRRs are being subjected include varfous combinations of natural circulation and reduced saturation margin operations with actual and simulated
- a. c.
power losses, steam generator isolaticns and boraticn and cooldcwn.
In view of the fact that natural circulation and reduced=saturation margin conditions are routine tc P~P. operations,l the PMR prograr s cannct be used for Bl'Rs in their entirety.
It v ould he possible to use the standby boron system to perform a boron mixing test similar to one of the Ph'P. tests,
- however, the experience gained would not justify the cleanup problem.
!'e consider one of the Pl".R tests, a sir.ulated less of all'a. c.
pcvher, to he feasible and one that should he performed on El~Ps.
The objective of +t>fs test is to familiarize operators with plant response and determine plant limitations in a blackout.
To perfcrm such a test, a real or simulated scurce of decay heat is necessary.

(In the PMR programs decay heat is simulated by input of fission heat or coolant pump heat.)
To use decay heat it will be necessary to defer the tes. until decay heat is avai'lable (as is permitted for one of the PRR tests in which reactivity control would be difficult). If you decide to perform this simulated loss of a. c. pcwer test with decay heat, you should perform this test within the first 1500 tiPD/T core exposure and itrmediately following 7 days of operation at 80 percent rated power or above.
If you decide to use a simulated source cf decay heat (such as steam from an external source or actual reactor power), you shculd perfcrm this test during the initial test program.
You should ccrrmit to the special low power test program for ycur facility now.
Cetai!ed test prccedures and safety analyses should be submitted for our review fcur weeks prior tc licensing.
In addition to the above, you should also commit to augmented operator training by participation in the pre-op and startup test programs.
Guidelines for the latter will be provided by the BPR Owners'roup.
The format for your test procedures should be ccnsistant with Regulatory Guide 1.68.
The results of the test program should be documented as part of the "Start-up Test Report" (see Regulatory Guide 1.16).
Taking the above actions will constitute a basis for your satisfactorv ccmt'liance with Item I.G.1.
Sincerely, cc:
