Dear Hr. Byram:
Pennsylvania Power and NRR staff met in Rockville, Maryland, on Thursday, March 30, 1995, to discuss PP&L's report NE-92-01, "Technical Basis for PP&L's Approach to ATWS Procedural Guidance."
During the meeting, the staff indicated that it would send to PP&L a limited set of questions regarding the analysis discussed in that report.
Accordingly, I have attached them to this letter.
Please provide a response not later than the end of April.
This information will help the staff to prepare for the upcoming meeting with the Advisory Committee on Reacto}
Safeguards to be held in Hay on the subject of EPGs.
The requirement affects nine or fewer respondents and, therefore, is not subject to the Office of Management and Budget review under P.L.96-511.
Sincerely,
/S/

RE U ST FOR ADDITIONAL INFORMATION CONC RN G AN SIS SUPPORTING D V AT 0 FROM BWROG EPGS R
V 4 (1)
What is the time required to inject the hot shutdown boron weight (HSBW) at Susquehanna2 Please provide the following data:
(a)
Target boron concentration in ppm (e.g.,
495 ppm hot)
(b)
Volume to be borated (c)
Injectipn rate (d)
Time to inject HSBW (2)
Provide data from SABRE runs for an MSIV closure ATWS with SLC at different water levels.
The data that we are looking for is:
(a)
Power, flow, water level, and in-core boron concentration versus time (b)
Time to reach the stagnation flow (c)
Suppression pool temperature (3)
Provide data for a run similar to the one documented in figures 2.1.2.4-1 of the old 1992 document (NE-92-001) - Water level at TAF with large power oscillations attributed to SRV cycling, or provide any other data.
which shows that the large power oscillations are no longer observed with level at TAF using the improve models in SABRE.
(4)
Describe the PPSL specific deviations from the standard BWROG EPG's.
Ignore this question if the October 1992 letter is still your position on deviations.
