: 4. MACCS2 is executed in three steps. The first module, ATMOS, calculates air and ground concentrations, plume size, and timing information for all plume segments as a function of downwind distance. The next module, EARLY, calculates the consequences due to exposure to radiation in the first seven days, which is the emergency phase of the accident. The last module, CHRONC, calculates the consequence of the long-term effects of radiation and computes the decontamination and economic impacts incurred due to the accident. | : 4.

- 1. I am a professional engineer with a Ph.D. in Physics of Nuclear Reactors from the University of Birmingham, United Kingdom, with 27 years of experience in safety analysis, emergency response plans, procedures and systems, radiation protection, radi ation transport, risk assessment, environmental impact assessment, st andards and guidelines, audits and evaluations, emergency exercises, courses and training and international project
- s. As discussed in my pre-filed testimony (Exhibit NYS0000241), I currently offer an advanced level course on MELCOR Accident Consequence Code Systems 2 ("MACCS2") and COSYMA, a code from the European Union that is similar to MACCS, for health physicists and engineers.
I have extensive experience with the MACCS and MACCS2 codes, including using the codes to calculate the consequences to the population for several accidents scenarios in the context of the Nanticoke 2 New Build Project for Bruce Power in Ontario. I also have extensive experience with COSYMA, a code from the European Union that is similar to MACCS, and have performed similar calculations for ESKOM in South Afri ca, Hydro-Quebec and New Brunswick Power in Canada, and the Canadian Navy. My education, professional qualifications, and experience are provided in Exhibit NYS000291.
- 2. I am currently Vice President of International Safety Research Inc. ("ISR"). ISR has been retained by the State of New York to provide expert assistance in the Nuclear Regulatory Commission ("NRC") relicensing proceeding for Indian Point 2 and 3.
- 3. To perform the consequence portion of its SAMA analysis, Entergy used the MACCS2 computer model, which was develope d by Sandia National Laboratories. Entergy used the MACCS2 code to estimate the cost of decontamination and cleanup after a severe accident at Indian Point.

The first module, ATMOS, calculates air and ground concentrations, plume size, and timing information for all plume segments as a function of downwind distance. The next module, EARLY, calculates the consequences due to exposure to radiation in the first seven days, which is the emergency phase of the accident. The last module, CHRONC, calculates the consequence of the long-term effects of radiation and computes the decontamination and economic impacts incurred due to the accident.
- 5. All of the MACCS2 inputs used by Entergy in its SAMA analysis that are associated with decontamination and cleanup costs, i.e. economic costs, are found in the CHRONC module.
- 6. In our December 21, 2011, report titled Revi ew of Indian Point Severe Accident 3 Off Site Consequence Analysis (NYS000242), ISR c onducted a sensitivity analysis to determine which CHRONC input parameters have the greatest effect on the offsite economic cost risk ("OECR"), which is the per year total economic cost of a severe accid ent used in the SAMA analysis.

For each of the sensitive parameters thus determined, ISR identified: the definition of the parameter; the input values chosen by Entergy; the explicit or implicit rationales for Entergy's selection of those values; a range of more appropriate values (where applicable) based on available data and relevance to curren t site-specific conditions of the area surrounding Indian Point; and a re-calculation of the OECR using the more appropriate value(s).

In our report, there are two references to a modification of the MACCS2 source code: Page 22: "The MACCS2 code restricts decontamination costs (CDNFRM) to a maximum of $100,000/person; therefore, ISR mo dified the source code to allow for the greater decontaminati on costs proposed here."

Providing the source c ode and test files is standard practice for nuclear codes since these programs need to be maintained and ported to different compilers and operating systems. Computer technology evolves quickly while the regulatory-accepted models change slowly. In addition, providing the source code allows the analysts to 4 scrutinize the calculation models and to make modifications wh en changes that had not been anticipated by the code designers become necessary.

In order to determine the overall costs as a result of ISR's proposed ranges of CDNFRM, ISR modified the source code to increase the upper bound of CDNFRM to $2,000,000/person.
